CP-SNT 1000W Power Supply
The CP-SNT 1000W can deliver 24Vdc @ 40A
and is powered from 3 phase 360-480V. It is
ideally suited for applications where large
numbers of DC powered devices such as
contactors, valves, fans as well as PLCs and
interface devices are used. A high output surge
capability means that highly inductive loads can
be powered from this supply.
NEW
An internal cooling fan allows this power supply
to be mounted on horizontal or vertical 35mm
DIN rail. Like the CP-SNT 300W power supply it
also offers analog outputs representing output
voltage and current and internal temperature. For
redundancy it is possible to operate multiple
power supplies in parallel. It is also possible to
operate 2 units in parallel for increased power.
Features:
• 360-480Vac, 3 phase input for global operation
• 40A continuous output and 80A for 1 second
surge capability
• analog outputs
• parallel operation capability
• 1 form C (SPDT) fault relay
• chassis mountable (hardware included)
