Overview Sorensen SGA Series
1-6 M550129-01 Rev AG
Parameter Specification
Resistive-Control Programming
Voltage 0 –5 k 
for 0-100% of rated output voltage

Current 0 –5 k 
for 0-100% of rated output current

Voltage-Control Programming
Voltage 0 –5 VDC or 0–10 VDC for 0-100% of rated output voltage
Current 0 –5 VDC or 0–10 VDC for 0-100% of rated output current
Overvoltage Protection (OVP) 0.25 –5.5 VDC for 5-110% or rated output voltage
Remote Control/Monitor Interface
On/Off control via contact closure, 6-120 VDC or 12-240 VAC,
and TTL or CMOS gate; output voltage and current monitors;
output voltage, current, and OVP programming; summary fault
status
Output Isolation
Output Float Voltage
Negative Output Terminal
±300 V(PK), maximum, with respect to chassis ground;
exceeding the limit will be detected as a fault by a protective
supervisory monitor and shutdown of the output will be
executed; this condition will be latched, requiring reset to
resume normal operation.
Isolation of optional Isolated
Analog Interface (J1) to output
negative terminal
1000 V(PK), maximum; Isolated Analog Interface (J1 signals)
are galvanically isolated from negative output terminal;
operation of Isolated Analog Interface signals should be at
SELV safety voltage conditions to chassis ground.
Reference of standard Non-
Isolated Analog Interface (J1) to
output negative terminal The standard Non-Isolated Analog Interface (J1 signals) is
connected to the negative output terminal and, therefore, is not
isolated from the output.
Parallel Operation
Parallel Group
Up to 5 units, of the same voltage rating, may be connected in
parallel for additional output current; specifications apply as for
single unit, with the exception that each additional paralleled
unit will add 0.3% to the output current accuracy. Contact
factory for applications requiring paralleling more than five units.
Series Operation
Series Group
Up to 2 units, of the same current rating, may be connected in
series for additional output voltage; see restrictions in Output
Isolation section.
