CP-SNT 160W 3 Phase
Switchmode Power Supply
The 3 phase CP-SNT 160W is a compact
switchmode power supply that continues
our tradition of more power from smaller
packages.
Requiring just 58.4mm (2.3”) of DIN rail, the
CP-SNT 160W has the following features:
• 380-480VAC input 50/60Hz
• multiple output terminals
• input and output plug-socket connectors
• over current protection
• output status LED
• output voltage adjustment
• fault relay output (Form C)
• load sharing
• high outrush (surge) capability

Relay is energized when power supply is
operating under normal conditions.
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 ter minal blocks.
