The Go ld Lin e 50-A a nd 9 0-A powe r su ppli es are p art o f a radi o pag ing t ransm it ter. The
50-A v ersion is u sed in t he GL-T 8500 transmitter; the 90-A version is used in the GLT8600 transmitter. The supplies provide power to other assemblies within the rack,
including cooling fans.

3.2 Physical Description
The supp ly c hass is m us t acc om mod ate m ore t ha n one typ e of eq uip ment ra ck. A ccor d ingl y ,
the assembly may vary sl ightly for proper cooling and mo unting requirements. Weight
varies with supply configuration. Also refer to T able 2-1. Figure 3-1, Front View of Gold
Line 50-A Power Supply shows the front of the p ower supply , and Figure 3-2, Top View
of Gold Line 50A Power Supply s ho w s a v iew of th e po w er supply from the to p.
The power supply i s mounted in a stand a r d 19-inch rac k. Some rack cabinets do n ot hav e
equipmen t access f rom the back ; others do. Th e steel sup ply chassis has no top or si des.
The protective front cover attaches to the front rail of the rack cabinet. The chassis is folded
on the bottom to allow it to slide between the rack-cabinet floor and two floor-mounted
bars. The chassis is held in place with two bolts tha t attach to the rack cabin et throu gh the
lower f r ont ed g e of the c has s is . Th e s upp l y i s mo unt e d a t the bottom of the equi pment r ack
in all single-transmitter configurations.
The suppl y requires little cabin et space . Refer to F igure 3-1, Front View of Gold Line
50-A Power Supply for detail. The front panel of five RUs (8.75 in) in height contains a
circuit breaker and fuses. Figure 5-1, Gold Line 50-A Power Supply Front-Panel
Controls and Indicators shows and describes thei r function s.

4 INSTALLATION AND SETUP
4.1 Precautions and Hazards
DANGER
The power supply chassis is not protected by
interlocks. Disconnect ac power before removing
any covers.
DANGER
The power transformer is heavy. Follow
precautions for heavy lifting.
4.2 Test Equipment and T ools Required
4.3 Component and Adjustment Locations
4.4 Installation
4.4.1 Inspection
4.4.2 Power Requirement
Common hand tools are required for assembly and disassembly. An RFI-immune voltmeter
is required for voltage measurement. Also refer to the system manual.
Figure 5-1, Gold Line 50-A Power Supply Front-Panel Controls and Indicators, shows the
location s of circuit breaker CB1 and the fuses. The only user-setup option is the powertransformer-input-voltage jumpering.
Ref e r to th e system m anual f o r insp ect ion in formation.
Refer to Section 2 for power speci f i cation s.

4.4.3 Input/Output Connections
Table 4-1, Input/Output Connect ions, shows the connections and functions of I/O connections for the power supply. The power transformer input must be jumpered for the expected
ac input voltage . Ref er to the proc ed ure in this paragra ph.

Power supply output connec tions are made on the filter capacitor assembly inside the
supply. Dc output is cabled directly to the power amplifier chassis. Dc output also goes to
other equ ipment via a co nnector and c able. Ac input co nnections are m ade directly to
circuit breaker CB1.
Table 4-2, Transformer Connection and Jumpers, shows the connections and jumper
settings for the power supply. The power transformer input must be jumpered for the
expected ac input voltage.

Figure 5-1, Gold Line 50-A Power Supply Front-Panel Controls and Indicators
shows a vi ew o f t he f ro n t pan el , w i th a d e scription o f t he operatio n of th e ci rcu i t break e r.
The function and ratings of fuses are clearly labelled on the equipment. Note that the fuses
are visible from the front panel. In most cases a blown fuse is obvious by visual inspection.
Note th eir cond ition when tro ub leshooting th e eq uipment.
5.2 Operating Instructions
The power supply operates in an unattended manner during normal system operation. Use
the circuit breaker and fuses when it is necesary to perform maintenance or troubleshooting.
Set the circuit b reake r to up po sitio n to turn on pow er supply. Set the circuit b reaker to
down position to turn off power suppl y.

6 THEORY OF OPERATION
6.1 Chassis Components
Refer to Figure 6 -1 and Figure 6-2.
Ferroreson ant transforme r T1 and reson ating capacitor C 1 act as a re servoir to allo w a
constant voltage ou tput despi te chang ing load c onditio ns as long as a consta nt voltag e is
applied to the input. It is electrically protected by circuit breaker CB1. There are taps on the
primary of the power transformer to allow various ranges of input voltage.
Output is r e ct ifi ed by CR1 and CR 2, a n d fil t ered by C2, C3, an d C 4, and C5 to prov i de a
filtered, stable dc output . Dc o utput for th e PA is cabled di rectl y from the f ilter c apac itor
assembly to term inals m ounted on the side of the equipment rack. Dc for the ex citer,
receiver, controll er, fans, and auxi liary equi pm en t is routed thro ugh plug J1.
6.2 Voltage Regulator Assembly
Refer to Figure 6 -3.
The 13.5-volt output of volta ge regulat or IC U1 is set b y the values of R1 thr ough R3. Ass ociated components filter and protect the assembly from damage due to electrical transients.

8 CHECKOUT AND TROUBLESHOOTING
8.0.1 Test Equipment and Tools Required
Common hand tools are required for assembly and disassembly. An RFI-immune voltmeter
is required to measure dc voltag es .
8.0.2 Precautions
Follow all danger advisories in para graph 9. 1, as ac powe r is ap plied to equipm e nt during
some tests. Only qualified technicians should perform these service items.
8.0.3 Resonator Capacitor Check
With main power applied, connect a dc meter across the supply dc output. Level should be
24-27 Vdc. .
This check is complete.
8.0.4 Transformer Check
With ac input pow er applied, conn ect an ac meter a cross the second ary winding of the
8.0.5 Diode Check
transform er.
Approximately twice supply voltage (50 Vac) should be presen t.
This check is complete.
With power off, disconnect each diode from the heat sink.
Check with ohmmeter in diode-checking mode from each diode anode to the heat sink;
normal dc conduction should be present from each one.
This check is complete.
