Compact power supply system DCS-RPS is a complete device designed to supply power to industrial, control, telecommunication and security systems with the use of telecommunication lines. The system allows for transfer of 1080 W of power to the distance of up to 5 km. The converter system is powered by 48 V DC nominal input voltage, 48 V DC nominal output voltage and by maximum transmitted power of up to 1080 W.
The DCS-RPS system contains:
- DC/DC-TPU module: converter from 48 V DC to 360 V (±180V) DC (central unit–power feeding side).
- DC/DC- RPU module: Aggregation of supply lines, diode isolation: and down converter from 360V (±180 V) DC to 48 V DC on the remote side (receiving side / supplied side).
- MP module: Remote control and monitoring (Ethernet or GPRS)
