Section 1 SPECIFICATIONS

Primary Input Power

50/60 Hz 3 phase 208-277 Volts 36 Amps source must have 15

KVA rating.

3 phase 380-460 Volts 4 wire wye 36 Amps source must

have 15 KVA rating.

1 Phase 208-240 Volts 50 Amps 50% duty cycle on 12 KVA

source 100% duty cycle on 25 KVA source.

Output

DC 6-50 volts

30-300 amperes 100% duty cycle at 10 KVA out (eg. 33 @300a)

Slope Control Flat to Vertical, Provides constant (potential) to

constant current operation.

Inductance Electronically provided 0-3 millihenries

Dual Slope

Capability (eg. CV during normal use - CC during Short circuit

transfer)

Idle Power Unit "On" contactor open - 80 watts (22w with fan off)

Unit "On", contactor closed no arc - 100 watts

Efficiency 92% at Full rated power

Pulse Output

Pulse adds to background level setting providing 0 to 100% output during

pulse.
Pulse "On Time" may be 0% to 100% of total pulse interva. Pulse repetition

rate variable from 20 pulse per second to 2000 pulse per second.
Pulse rise time - variable (external only) - 100usec min. - sym rise and fall.

Controls

All functions are calibrated in 0-100% of full scale and may be controlled

remotely with 0-10 volts signals. For use with Robot Control Computers,

desired functions may be commanded from the control computer with

remaining function locally controlled at the power supply.
