Surge
13A for 1 second
Unit will shutdown if surge exceeds 1 second
Overload
Automatic restart if overloaded. Unit restarts after
approximately 4 seconds.
Relay Output
Contacts rated 30VDC 1A or 125VAC, 1A
maximum, Form ‘C’ SPDT.
Relay is energized when power supply is
operating under normal conditions.
Load Sharing
Maximum 2 units can be connected in parallel for
load sharing. Derate supplies to 80% capacity
(5.2A) when load sharing. Follow these directions
for correct operation.
1. Adjust the output voltage of each power supply
to the same value before connecting them in
parallel (±200mV).
2. Connect wires of the same length from each
power supply to terminal blocks.
3. Connect the load(s) at these terminal blocks.

•g(earth) terminal should be connected to earth ground
for safe operation.
•Outputs of power supplies can be connected in parallel.
•Outputs of power supplies can be connected in series.
•Outputs of power supplies can be connected to produce a
bi-polar output.
•Power supply should be mounted allowing for natural air
flow through the ventilation holes.
