Introduction
WARNING: THIS APPARATUS MUST BE EARTHED
The CPS250/CPS275 are linear power supplies which, like other linear supplies, produce DC voltages by rectifying, smoothing and regulating AC voltages from the secondary windings of a mains transformer. Soundcraft mixing consoles employ a number of dc voltage supply levels in their op eration and these are all provide d at the output of each supply unit.
The CPS275 provides higher currents than the CPS250. The CPS275 also has the capability of being linked to a second CPS275 to provide a utomatic power backup in the event of one of the units failing.
In regulating these voltages there is considerable heat generated, the dissipation of which is achieved through a substan tial internal heat sink. A fan is incorporated which draws air over the heatsinks to provide adequate heat dissipation for the regulators and reduce the outer case tempera ture .
The CPS250/CPS275 is designed for installation in a 19" rack unit, oc cupyin g 2U of rack height. Refer to the section "RECOMMENDATIONS FOR INSTALLATION" on Page 5.
LED indication is provided on the front panel to show operation of the regulating circuits.
SHORT-CIRCUIT PROTECTION
The +/-17V rails can withstand a short to ground or each other for up to one second; if the short circuit remains for longer than one second then both of the 17V ra ils will be shut down. To reset them the supply must be switched off for 6 seconds and then switched on again.
The +5V and +48V are current limited and will self rec over whe n any short ci rcuit is removed.
2 Introduction
MAINS VOLTAGE SELECTION
Special attention should be paid to the fo llowing infor m atio n:
Do not change the voltage setting without first turning the unit off and unplugging the mains lead.
This unit is capable of operating over a range of mains voltages by means of a 4-position mains input fuse carrier. It is important to ensure that the correct voltage setting is selected for the level of local mains voltage supply, for safe, uninterrupted operation of the unit. Voltage selection is achieved by positioning the fuse carrier so that the required voltage appears next to the arro w which is moulded in the conne ctor. In this way the unit is set up for operation at one of the following ranges of mains supply:
NOMINAL VOLTAGE OPERATING VOLTAGE RANGE
(+10/-15%)
Vrms AC Vrms AC
230 196 - 253 115 98 - 126 100 85 - 110 85 73 - 93
To remove the fuse use a small screwdriver to prise the fuse carrier from its location in the connector.
To avoid risk of fire use the correct value fuse, as indicated on the unit.
REPLACING MAINS FUSE
Switch the ON/OFF switch to the OFF position. Remove the mains lead from the connector. Use a small screwdriver to prise th e fuse carrier from its location i n the connector. Check the fuse and replace if necessary; also check that the voltage selection is correct for the mains supply level be fore switc hin g the unit ON agai n.
In the event of repeated failure of t he mains fuse co nsult the Sound craft dealer from where the unit was purchased.
This unit contains no user serviceable parts. Refer all servicing to a qualified service engineer, through the appropriate Soundcraft dealer.

Recommendations for Installation
The CPS250/CPS275 power supply is provided with front panel fixing hol e s for 19" rack-mounting and will occupy 2U of rack space.
As with any power supply that contains a large mains-voltage transformer, it is preferable to provide a degree of physical isolation of the unit from other electronic equipment, particularly that which carries low level audio signals, to avoid any possible hum pick-up. For this reason the unit is used with a long (7 metres) output cable to enable it to be positioned away from the m ixin g con sole.
For the same reason, when rack-mounting it is preferable to avoid locating the unit adjacent to signal processing equipment.
It should be noted that if a complete rack containing a CPS250/CPS275 unit is to be operated from a different mains supply level, then the unit should b e withdrawn from the rack in order to reselect the mains voltage setting, at the same time as resetting a ny other equipment.
The other important consideration when rack-mounting the unit is the need for natural convection of air over the case and an unrestricted air flow through the unit. Note that air is drawn in at the rear of the unit and expelled through the fron t pa nel.
Good ventilation BELOW the unit, in the floor or back of the rack, and similarly ABOVE the unit, at the top of the rack, will ensure a path for c ont inuou s ai r flow.
Other equipment in the rack which is known NOT to produce a signific ant amount of heat should be mounted BELOW the unit. Equipmen t that also relies on good air flow within the rack (ie. most power amplifiers a nd other power supplie s) should be given due consideration and some space should be provid ed between such units and between these and the CPS250/CPS275 unit. Forced convection, by means of a fan-tray, ma y be desirable in this situation.
The CPS250/CPS275 will operate as a free-standing unit without requiring any special cooling arrangement, but should not be allowed to be accidentally or deliberately covered over in any way.
Do not operate the unit with the top cover removed.
The air intake and outflow holes must be inspected regularly and cleaned if necessary to maintain good airflow through the unit. This will be particularly important if the unit is used in a dusty environment.
Finally, some consideration should be given to the ea rthing arrangement of the system at the centre of which are the console and the CPS250/CPS275 (and any other Soundcraft power supply units). The console chassis is earthed, through the mains earth, via the power supply. When rack-mounting the CPS250/CPS275(and any othe r Soundcraft power supply units) care should be taken to avoid any possible ‘ground loops’ in the system which would introduce audible hum to otherwise clean audio signals. Ground loops may occur where signal proces sing equi pment, pa tche d to the console, has its signal earth commoned to the equipment c hassis. The gro und loop is
6 Installation
formed if this chassis and the power supply chassis are in electrical contact through the fixing rails they share in the rack. To avoid this situation, standard isolating washers may be employed when fixing the power supply (or supplies) or any other unit into the rack.
W A R N I N G : THIS APPARATUS MUST BE EARTHED. Under no circumstances should the mains earth be disconnected from the CPS250/CPS275 power supply unit.
GENERAL
As with all electrical/electronic equipment care should be taken when handling this unit. Avoid general mishandling and do not drop. Avoid storage and operation in dusty locations and do not expose to corrosive atmosphere s.
To avoid risk of fire do not expose this unit to rain or moisture.
Retain all packaging for transportation in the event of the unit requiring servicing. Retain this manual safely, along with a ll oth er rel ev an t doc ume nt s .
For touring/mobile transportation it is advisable to install the CPS250/CPS275 in a flight case to provide mechanical protection. Refer to your Soundcraft dealer for a suitable case.
Where the CPS250/CPS275 is enclosed in a touring case, provision must be made for adequate ventilation to the rear of the unit to ensu re unre stri ct ed s upply o f a ir fo r th e cooling fan.
Use only the high-current mains lead supplied, not the more common 5A type supplied with other equipment.

Circuit Description
The CPS250 and CPS275 power supplies provide +/-17V at 4 Amps an d 5 .25 Am ps respectively. Both give +5V at 1 Amp, and +48 V at 0. 3 Amp. The PCB is SC3803.
THE +/- 17V RAILS.
This consists of two identical +17V supplies connected together to give +/-17V. Each 17V supply is a linear regulator with conventional fullwave rectification and 20,000uF reservoir capacitors. This is combine d with a second powe r supply that sits on top to power the driver transistors and the control IC; this reduces the minimum voltage drop across the series-pass device a nd so improve s effic ie nc y.
The main series-pass element is a 250W discrete bipolar transistor mounted on a fan-cooled heatsink. The voltage reference and servo control amplifier are provided by a 723 regulator IC.
The circuitry of the +17V regulator is described in detail below:
The +17V Supply.
The transformer secondary is fused by F1. Secondary fuses will normally only blow in the event of serious failure, such as a maj or short in the AC wiring or a failed bridge rectifier.
The fullwave bridge rectifier is mounted on the heat sink, at the ho ttest end as i t is the most heat-tolerant of the semiconductors. For safety reasons, the reservoir capacitor is discharged by bleeder resistors R39,40 at switchoff; this takes about 10 seconds. The unregulated DC voltage is approx +26 to +29V.
The 723 IC contains a 7.15V nominal Zener diode, defining the voltage that appears at Pin 6. R5 is in series with the positive in put of the serv o opamp (Pin 5 ) and is mad e roughly equal in resistance to the feedba ck divider R7,11 etc to minimise bias -current offsets.
The feedback divider R7,8,11, & PR1 derives a fraction of the output voltage and delivers it to the negative input of the servo opamp. (Pin 4) The negative feedback keeps this point also at 17.15V, so the actual output voltage is determined by the feedback divider ratio, which is trimmed over a narrow range by PR1.
The output of the servo opamp controls the output through TR1, an emitter follower driving the series-pass device TR3. The power supply to TR1 is take n from the +12V supply developed across C23. This has its 0V side connected to the positive unregulated DC supply of 26 - 29V, (at nominal mains) giving a total v oltage of approx 38 - 41V for the driver; this also powers the 723 IC via R1. This subrail markedly reduces the minimum drop across the pass elements and therefore increases the efficiency.
10 Amp Schottky diode D25 on the output allows supplies to be paralleled for redundancy. This is only fitted for the CPS275 option.
Overcurrent Protection.
The power supply is protected against short-circuits and overload by a dual-mode protection system; brief overloads are deal t with by constant-current protection, while prolonged overload causes both 17V rails to shutdown. Reset is by turning the mains power off for not less than 6 seconds.
14 Technical Description
The constant-current prot ectio n syst em wo rks in t he stan dard w ay; wh en an attemp t is made to draw excessive current, the output voltage is reduced so that no more than a fixed maximum can be drawn. However, the high current capability of this PSU means that long-term constant-current protection alone is not practical as the dissipation in the pass devices is too high for the cooling system to deal with, and in time they will overheat.
The constant-current system meas ures the outpu t curre nt by sen sing the volt age drop across resistors R18,19 in parallel. When it reaches approx 0.60 V the internal protection transistor in IC1 is turned via R41, and the output voltage on pin 10 pulled down to limit the current supplied.
If this condition persists for longer than one second, then both rails of the +/-17V supply are shut down by the Mutual Shutdown System, described belo w.
The Mutual Shutdown System.
Equipment containing some kinds of op-amp is vulnerable t o damage when only one of the +/-17V rails fails, as in this case excessive supply currents can be drawn, damaging fuse resistors on the modules.
When both 17V supplies are working normally, DZ1,DZ2 are conducting, LED1 is on and opto-couplers OP1,2 have their photo- transist ors c onducti ng. The ref ore TR5 does not conduct, and the supply works normally.
If the -17V rail collapses, there is no longer e nough voltage to kee p DZ1,DZ2 on, and OP1 switches off. TR5 is turned on by R16, with R28,30 and C40 providing a time-delay to prevent spurious operation on transients, or brief overloads which are dealt with by the constant-current protection s ystem . TR5 now pulls down an interna l node of IC1 via pin 13, and the +17V supply is shut down.
In the same way, if the +17V supply fa ils, OP2 switches off, TR6 is turned on by R17, and the -17V supply is shut down.
The -17V Supply.
This is identical in operation to the +17V section de sc ribed above.
The +48V Supply.
Max current rating is 0.3 Amps. The +48V phantom supply is based on the special high-voltage regulator TL783C. (REG1) The AC input is fused by F3 and fullwave rectified by D15-18; C31 is the reservoir capa citor. C32 ensures HF stability of REG1. The TL783C maintains a fixed 1.27 V between its ADJ and OUT pins, so the adjustable voltage-divider R22-PR3-R23 gives an output of approx 48V. Thi s can b e finely adjusted by PR3. C33 minimises output ri pple. Rail indicator LED2 is powered through DZ3,4, which total 30V, so even a partial fall in rail voltage will extinguish it.
Two protection diodes are inc luded. D13 protec ts t he regul ator from reve rse voltage if there is a charged capacitor across the output but the voltage on C31 has collap sed. D20 prevents the ADJ pin from rising above the OUT pin (due to the char ge on C33) if the output is shorted.
Diode D22 on the output (CPS275 only) allows supplies to be paralleled for redundancy.
Technical Description 15
The +5V Supply.
Max current rating 1.0 Amps. This supply is primarily inte nded for powering console internal computers; it also powers the cooling fan.
The AC input is fused by F4 and fullwave rec tified by D9-12, with C36 as the rese rvoir capacitor. The LM340 regulator has a fixed 5.0V output. C35 ensures regulator stability.
A protection diode is included; D14 protects the regula tor from reverse voltage if there is a charged capacitor across the output but the volta ge on C36 has coll a pse d.
Diode D23 on the output (CPS275 only) allows supplies to be paralleled for redundancy.
16 Technical Description
Servicing
SAFETY.
These safety notes are directed to those te s ting and re pai r ing thi s powe r s uppl y.
Legal requirements mean that we must not encourage untrained personnel to take the lid off.
Servicing should only be carried out by a competent service engineer.
This supply contains mains voltages on the voltage select PCB, the mains switch, etc, and the usual precautions must be taken.
The main reservoir capacitors have a capacity of 20,000 uF, and are charged to +26V.
THIS CAN BE DANGEROUS.
The danger lies not in the voltage, but in the la rge currents that will flow if the capa citor terminals are shorted. A small screwdriver will simply disappear in a violent explosion. The main bodily danger is from metal watchstraps, etc. Serious burns are very likely if these contact the capacitor.
For safety reasons, the reservoir capacitors are discharged by bleeder resistors at switchoff; this takes about 10 seconds.
The unregulated supply to the + 48V regulator can reach +90V on high mains, and should be treated with some respect.
Initial operational tests on the power supply can be carried out by switching the unit ON and checking the voltages prese nt on the output connectors on the ba ck of the unit. While the unit remains disconnect ed from the mixing console some of the DC voltage rails are floating with respect to each other, that is they do not all have a commo n reference within the unit. When connection is made to the mixing console various output pins become earthed to a common star-point, which has a mains earth return in the power supply cable itself.
An indication of obvious fault condition is the failure of one or more of the front-panel LED’s to light.
Any fault condition, with the excep tion of simple mains fuse failure due to underrating or an unusual mains input condition, will require removal of the top cover to enable fault correction. This is achieved using a cross-head screwdriver to remove the six retaining screws and washers. Carefully lift the co ver to avoid the earth co nnectin g lead to the cover from snagging. Place the cove r fac e down behi nd the unit .
WARNING: At the front of the unit just behind the front panel is the MAINS SWITCH, which carries HIGH VOLTAGES directly from the mains input. Similarly on the rear panel is the MAINS INPUT SOCKET/MAINS VOLTAGE SELECTOR. Care MUST be taken when carrying out any servicing operation with the top cover removed.
Technical Description 17
FAULTFINDING NOTES.
+/- 17V RAILS.
If one side of the +/-17V supply is not working, the mutual shutdown system will close down both sides of the supply. This m akes faultfinding diffic ult as it is o ften not obvious which side has failed. The mutual shutdown can be disabled by linking pins 4 and 5 on BOTH opto-isolators
IT IS ESSENTIAL THAT THIS IS REMOVED AFTER SERVICING IS COMPLETED! FAILURE TO DO THIS MAY CAUSE SEVERE CONSOLE DAMAGE IF ONLY ONE 17V RAIL SHUTS DOWN.
If there is no power to the 723 IC (eg if R1 or R2 is open- circuit) the output will remain low, but no damage occurs.
+8V SUPPLY.
This is a completely standard IC regulator c ircuit. The regulator REG3 is the only part that is likely to fail.
REPLACING COMPONENTS
Replacement of any components should be undertaken only after switching the power supply unit OFF and disconnecting the mains supply lead from the power supply unit.
Replacement of any of the fuses in the power supply units is possible without the removal of the circuit board.
The fuses are held in open fuseholders on the top of the boa rd. These can be car efully removed by hand. Ensure that the insulating fuse covers are replaced with the new fuses.
Various components are mounted along the heatsink extrusion. The extrusion/pcb assembly must be removed from the case to gai n access to the unders ide of the pcb in order to unsolder and/or undo the appropriate component. They can be removed by desoldering the pins, where appropriate , and unsc re wing the fixing nuts or the fi xing screws, taking care to retain the small insulating bush(es).
Retain carefully the mounting pads and plastic insulating bushes where fitted.
THESE MUST BE CORRECTLY REFITTED TO AVOID DAMAGE TO THE
.
UNIT
The correct high efficiency mounting pad must be used, and this should be replaced if it appears to be damaged (see the Parts Lists for the relevant Soundcraft Part Numbers). When refixing or replacing the device, it is important to screw the device down before resoldering the pins to avoid stressing the pads on the c ircu it boa rd.
NOTE : The heatsink bracket is earthed through its mechanical contact with the rest of the chassis and so a faulty mounting pad may cause the output of its regulator to be connected to earth.
Take care not to bend the pins on the regulators, or to strain the corresponding pads on the circuit board
18 Technical Description
Reassembly is simply a reverse of the procedure above. Particular care should be taken when fixing the regulators, ens uring that the pins are not bent or the circuit board pads strained when the fixing screws are tightened. The regulator screws are tapped into a relatively soft aluminium heatsi n k . strip the thread in the heatsink. High performance mounting pads must be fitted between the regulators and the heatsink. The re gulators must be check ed for isolation from the heatsink using a multimeter.
Re-dress cable forms in their original pos itions and secure where applicable with cable ties.
DO NOT OVER-TIGHTEN
or you will
OUTPUT VOLTAGE ADJUSTMENTS
The +/-17V and +48V rails are adjustable via trimpots on the pcb. After any repair these should be checked +/- 0.1V, and the 48V rail to 48.3 +/- 0.1V. The 5V rail is not adjustable.

and adjusted if necessary. Set the 17V rails to 17 .5V
GENERAL
Before replacing the top cover on the unit, carefully remove any dust from surfaces within the unit.
Carefully check all wiring connections and ensure that there are no loose parts lying around inside the unit.
