WARNIN
G
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance equipment
must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/use r must ensure
that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact
with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses
during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary sales
organizations can accept any responsibility for personnel, material or inconsequential injury, loss or
damage that results from improper use of the equipment and accessories.
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might

provide a precise output with low distortion. Available voltage ranges are 0-150 Vac, 0-300 Vac and 0400 Vac in AC mode. Various models are available that can provide either single or three phase output
power levels in an AC only mode of operation.
All BPS models provide interface features such as a standard RS232C, USB, IEEE-488 interfaces and an
available LAN option.
The BPS Series units are contained in a floor standing enclosure on casters. This allows the units to be
moved around more easily.
Read the installation instructions carefully before attempting to install and operate the BPS Series power
systems. If you have any questions or concerns please contact the factory prior to applying power to the
system.

Repetitive Peak Current:
Note: Maximum Peak Current shown. Value shown reflects absolute peak current protection level. This level may not be reached
under all load conditions. Depending on load conditions, peak current may max out at lower levels due to amplifier output impedance.
Note: A repetitive peak current limit function is provided which will generate a fault and shut off the power supply if the peak
current drawn by the load exceeds the maximum level for more than 30 seconds. During this time, the amplifier will limit the peak
current at a somewhat level above the maximum level but it is not allowable to run in this mode indefinitely. This should provide
sufficient time to ride through any startup/inrush load conditions.

2.6 Special Features and Options
Controller Features
Parallel Operation: Two BPS75 or BPS90 units can be paralleled in a three-phase configuration (with one
master controller and one auxiliary unit) for 150KVA and 180KVA systems. Only the
master unit requires a controller in this setup. The auxiliary units are controlled through
the system interface connector.
Controller: Programmable controller front panel assembly.
Output Relay: Standard output relay feature to isolate power source from the load.
Output On/Off: The output relay can be used to quickly disconnect the load. A green status indicator
displays the status of the output relay.
Firmware / Software / Hardware Options
- HV Adds 400 V AC only output range.
-ES Emergency Shut off switch. This option key lock push button is installed on the front
panel of the master BPS if ordered with the BPS system. When pushed in, the main AC
contactor is opened disconnecting the AC input power to the BPS input transformer.
Note that the controller (and LCD display) will still be powered up but no power is
available to the amplifiers and there will be no output power either. The controller runs
off the LV supply, which must be turned off with the front panel breaker.
After the ES has been pushed, the provided key will be required to release it. Once the
ES button has been released, the BPS must be powered down using the front panel
circuit breaker and turned back on to start up again.
Note: Do not misplace the 2 keys provided, as no duplicates are available from CI. If
lost, the ES switch must be replaced. In that case, contact AMETEK Programmable
Power customer service. (service.ppd@ametek.com

3.3 Mechanical Installation
The BPS power source is completely self-contained power sources. They are to be used free standing on
a solid surface. The units are fan cooled, drawing air in from the front and exhausting at the rear. The
front and back of each unit must be kept clear of obstruction and a 6” clearance must be maintained to the
rear. Special consideration of overall airflow characteristics and the resultant internal heat rise must be
considered at all times to avoid self heating and over temperature problems.
3.4 AC Input Connections and Wiring
Three-phase Delta or Y AC input voltage of suffici ent amperage (consult AC input specifications for
maximum AC current per phase) is required to power the BPS Series.
Note: AC power should be routed through a properly sized and rated three-phase PROTECTIVE
CIRCUIT BREAKER or similar branch circuit protection device with disconnect capability.
This will protect building wiring and other circuits from possible damage or shutdown in case
of a system problem. It will also facilitate removing AC input power to the BPS system in case
of service or reconfiguration requirements.
Note: AC input wiring and connections must conform to local electrical safety codes that apply.
Always consult a qualified electrician prior to installation of any BPS System.
AC input connections are to be made directly to the input fuse block. The input fuse block is located on
the lower left hand corner of the front of the BPS30 and BPS45 chassis. To access the input fuse
connection block, the protective front cover needs to be removed first.
CAUTION: Always disconnect any input power completely when removing any
protective cover and allow the internal capacitors to fully discharge (minimum of 15
mins) before removing any cover.) See Figure 4-2 for details.
No wiring for AC input connections is provided with the BPS Series and must be provided by the end
user or installer. Input wiring should be entered through the right hand side (when facing the back of the
BPS cabinet, see Figure 4-4) wire access opening located at the rear bottom of the BPS chassis. A wire
channel (marked as [2] in figure below) is provided below the input transformer to allow the input wiring
to be routed to the front of the unit where the connections are to be made.
WARNING: The power source's input connection wiring gage (size)
must be sized for the maximum input current rating to ensure user safety and
avoid possible power source damage, regardless of the actual output load.

Note: To comply with product safety requirements, EARTH GROUND must be connected to the
chassis of the AC power system using the ground stud located directly below the AC input fuse
block. Use a Green/Yellow ground wire.
Note: DO NOT USE THE NEUTRAL CONNECTION OF A 3 PHASE Y AC POWER
CONNECTION IN PLACE OF A TRUE EARTH GROUND CONNECTION. AC power
system neutrals cannot be used for protective earth ground.
The mains source must have a current rating equal to or greater than the input fuses and the input wiring
must be sized to satisfy the applicable electrical codes. The front cover must be re-installed prior to use
and the strain relief provisions located at the rear bottom of the unit must be used to maintain protection
against hazardous conditions.

The input power cables and protective circuit breaker used must be large enough to handle the input
current and input voltage of the power source and must conform to local electrical codes. Consult a
qualified electrician prior to installation. Table 3-1 shows the size of the cables that may be used per BPS
cabinet. Note that wires must be sized to accommodate the worst-case maximum current that may occur
under low line conditions. Local electrical codes may also require different wire types and sizes. These
ratings should also be used when selecting a circuit breaker or equivalent disconnect device.
Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate the
voltage drop from the following formula:
2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP

* Using high temperature rated wire. Always consult the National Electrical Code and local code regulations for
proper rating and size of wire cabling prior to installation.
CAUTION: Capacitors in the power source may hold a hazardous electrical charge even if the
power source has been disconnected from the mains supply. Allow capacitors to discharge to a
safe voltage before touching exposed pins of mains sup ply connectors.
Power modules need at least 15 Minutes to discharge to safe levels before they can be removed.
3.5 AC On/Off Circuit Breaker on BPS Series front panel.
It is important to understand the purpose and operation of the On/Off circuit breaker of the BPS Series
located on the lower left side of the front panel. This is a 2A rated breaker that is used to engage and
protect the LV Power supply of the BPS chassis only. The LV Power supply provides DC bias power to
the entire BPS system. The AC input power is routed through a set of three AC line fuses (F1, F2 and F3)
located in the lower left bottom corner of the BPS. (See Figure 4-2 for fuse locations). These fuses
protect the three BPS amplifiers and the AC input transformer from excessive input currents. The AC
input power is connected to the input transformer through a large three-pole contactor. Removing AC
power to the LV Power Supply by opening the front panel circuit breaker (moving the lever to the down
(OFF) position) will cause this contactor to lose its coil voltage and will result in it opening and
disconnecting the input transformer and amplifier from AC mains input.
Note: If any system failure has occurred on any part of the BPS system, AC input power must be
removed immediately and not restored until the system has been inspected by a qualifier
service technician. Repeatedly applying power may cause further damage.
Always turn off the On/Off Circuit breaker before re-applying AC input power .
CAUTION: The AC input fuses can only be checked is the BPS unit is completely de-
energized and disconnected from any AC power input.

Note: Under no circumstances should AC input power be applied if one or more of the AC input
line fuses have failed and opened up.

3.6 Output Connections
3.6.1 Output Wiring
The output terminal blocks, TB1A and TB1B are located at the front of the unit behind the bottom access
panel. See Figure 4-2 for details.
Three phase output line connections are made to terminal block TB1A. The phase outputs are labeled A,
B and C. The neutral connection (if needed) can be made on terminal block TB1B. If the model used is
a BPS30-1 or BPS45-1 with single-phase capability, the single phase A output connection is available on
TB1B as well. Note that the neutral for either single or three-phase mode is always located on TB1B.
The neutral connection is always required for single-phase output BPS30-1 or BPS30-3 and may be used
if needed for the EUT for BPS30-3 and BPS45-3 models with three-phase output modes.
The external sense inputs allow the power system output voltages to be monitored directly at the load and
must be connected at TB2 when the sense is programmed for external. The external sense input does not
have to be connected when Internal Sense is programmed. The external sense wires are to be connected
to TB2 on the rear panel and should be run using a twisted shielded cable. See Figure 4-4 for location of
TB2 and Figure 4-5 for shield connection detail.
Note: For External Sense connection, a shielded cable MUST be used with the shield connected to
chassis ground at the Ext. Sense connector. (See Figure 4-5).
External sense is recommended for multi-cabinet systems is the output wiring from the cabinets to the
common output terminal block supplied is not of equal length.
Figure 3-5: External sense cable shield connection to chassis ground
Note: The output of the power source is isolated from the input line and floating with respect to
chassis ground. If needed, either side (HI or LO) may be grounded.
If the EUT changes frequently, you may want to consider using some quick disconnect scheme external
to the BPS so it will not be necessary to power down the BPS and remove the front covers. This can take
the form of a panel-mounted socket (1 or 3 phase) of sufficient current and voltage rating. (Not supplied
with BPS)
The output power cables must be large enough to prevent a total voltage drop exceeding 1% of the rated
output voltage between the power source and the load. Table 4-2 shows the size of the cables that may
be used. Note that wires must be sized to accommodate the maximum current that is available. This may
