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.
Size
16-1/4" x 8-1/2" x 24" (41.3 cm x 21.6 cm x 61 cm)

10,000 ft. elevation. Normal handling for electrical equipment, units may be
stacked or mounted side-by-side. Access required to rear of unit to connect
primary power cable. Cooling air inlet in rear - needs at least 4" clearance
from wall. Auto Over-temp shut down.
