PREFACE

THE STRONG INTERNATIONAL switching power supply Type 62-80100 is

designed to operate a xenon bulb in all theatrical lighting applications for Strong lamphouses. This

unit will operate all xenon bulbs rated from 1000 to 3000 watts throughout their full operating ranges

(20-35 V.DC, 40-100 A.DC). The power requirement for this unit is 208/230 (200-240) V.AC, 30

amperes single or three phase, 50/60 Hertz.

INCOMING LINE POWER is transformed from 208/230 volts AC to a low voltage,

high current DC output. The incoming AC line is filtered to eliminate noise and is then converted to

DC. This DC voltage is switched on and off by a solid state switching circuit, and converted to a 60

kHz. square wave. The square wave is fed into output transformers to provide low voltage and high

current. Rectifiers convert the 60 kHz. signal to DC, and the output is filtered to eliminate noise and

ripple. Output to the xenon bulb is adjustable through use of potentiometers.

A STEPDOWN TRANSFORMER reduces the incoming line to 120 V.AC to power

the lamphouse igniter and blower(s). A separate three ampere circuit breaker protects the control

circuit in the event of a lamphouse component malfunction.

PROTECTIVE CIRCUITS include a high temperature limit switch and under- and

overvoltage detection. The thermal switch will open and interrupt power supply operation if internal

temperatures exceed 175° F. (80° C.). A drop in AC line voltage, reducing AC supply to inadequate

levels, or a high voltage AC spike, will also disable the power supply until the voltage is corrected.

A MULTI-PIN MS RECEPTACLE is standard on units supplied for use with Strong

follow spotlights and projection consoles. A lamphouse termination panel may be ordered as an

option for motion picture or studio applications using Strong lamphouses without the corresponding

MS plug.

NOTICE

REFER ALL SERVICING of this unit to an authorized Strong International
Equipment Dealer. The 62-80100 Switching Xenon Power Supply employs
solid state circuitry requiring sophisticated diagnostic equipment not gener­ally available to field service personnel. Hazardous high voltages exist within
the power supply cabinet.

INSTALLATION - OPERATION

CAUTION: This equipment operates at hazardous v oltages, and
should be operated by qualified, trained personnel

only.

Do not

remove power supply cover panels when the unit is energized.

When positioning the power supply, allow several inches clearance around the power

supply cabinet for unobstructed air flow. If the intake or outlet grilles are blocked, thermal switches

will shut the unit off to prevent heat damage.

Connect the lamphouse DC and control leads to the output side of the power supply

prior to connecting to AC power. Lamphouse to power supply connections, when not terminated in

a MS plug, are illustrated on the INTERCONNECTION DIAGRAM in the lamphouse instruction

manual. Make certain the lamphouse ground lead is connected.

Power leads run to the unit must be of the correct size and type to conform to local

codes. Shield in conduit as required. The power supply will not energize until the circuit breakers

on the side of the cabinet are placed in the ON position.

A four-prong, female plug is furnished to mate to the AC receptacle

mounted to the power supply. Connect 208/230 V.AC three phase input to

terminals X, Y, and Z. Connect single phase input to terminals X and Z only.

Single or three phase neutral is not required for installation of this unit. Attach

an adequate earth ground to the green ground terminal.

In areas using 380/440 V.AC three phase power (Europe, etc.),

connect the unit for single phase operation only, using (1) phase line on X and

a neutral on Z. AC input as measured across connector terminals X and Z

Ground prong

keyed

must not exceed 240 V.AC. Attach an adequate earth ground to the green

ground terminal.

See the warranty information packed with the xenon bulb for correct operating cur-

rent. Do not, at any time, exceed the maximum current level specified by the bulb manufacturer.

Current output to the bulb is set through use of the adjustment potentiometer(s). If

installed in a Strong Xenon Projection Console, the adjustment potentiometer (62-70032) is gener-

ally remoted to the console control panel. When the remote option is not utilized, a potentiometer

printed circuit board assembly (62-70028) is connected directly to the current control receptacle.

Check the lamphouse ammeter upon the first bulb ignition, and adjust the current con-

trol potentiometer to set the desired bulb current. On Strong projection consoles, this potentiometer

is usually remoted to the lamphouse control panel adjacent to the ammeter. Rotate the potentiometer

clockwise to increase current, or counterclockwise to reduce current. When the potentiometer printed

circuit board assembly is used in place of a remote control assembly, a second (fine) adjustment poten-

tiometer is included for output changes in small increments. The PC board is marked coarse and fine

to identify the (2) potentiometers.

The stepdown transformer for the lamphouse control circuit is factory prewired.

Terminals 2 & 4 supply 120 V.AC to the lamphouse. After completing the lamphouse interlock circuit,

the 120 V.AC returns to the power supply on wires 5 & 6 to energize the control printed circuit board

at plug PL5 upon closure of the LAMP ON switch. The same circuit (5 & 6) energizes the AC

lamphouse igniter.

A second, two-terminal barrier strip located next to the DC output terminals is in-

cluded in spotlight power supplies. Wires 7 & 8 (220 V.AC) terminate at this position, and supply

voltage to lamphouse blowers in Gladiator III spotlights through MS connector Pins I & J. These

wires are unused in Super Trouper and other spotlights, but are included to permit interchanging

power supplies between Super Troupers and Gladiators. DC output must be re-set after changing

a power supply from one system type to another. See the spotlight manual for current requirement.

The DC Pulse Igniter used in some Strong lamphouses does not require the AC control

voltage supplied on 5 & 6, but will be actuated from the high DC open circuit (no load) voltage

normally generated by the power supply. The DC voltage will fall to a lower sustaining level (20 - 35

V.DC) after the xenon bulb ignites, and the DC Pulse Igniter will cease operation when the DC voltage

drops below 130 V.DC.

MAINTENANCE

The power supply requires very little service to insure correct operation. Periodically

check all electrical connections for tightness and condition, especially those in the DC circuit. Dis-

colored terminals may indicate oxidation which will increase resistance.

Clean the ventilation inlet and outlet grilles on a regular basis to insure good air flow.

Thermal switches mounted to the power supply will interrupt operation of the power supply in the

event of overheating.

The blower motors are permanently lubricated. The 62-80100 power supply includes

(2) blowers and requires operation of both fully functional blowers for correct operation. In the

event of a blower failure, a replacement blower must be installed immediately.

Service interruptions because of low (below 200 V.) or high (over 240 V.) AC input

require adjustments to the AC supply line. To protect the equipment, voltage level protection cannot

be bypassed.
