Centurion Rectifier System
 |
The Centurion Rectifier System comprises a low profile 3.5” (2 RU) shelf which accommodates up to three 550 watt, -48 or +24 volt hot-swap rectifiers, plus a voltage control and alarm module. The system is scalable/adaptable for N, N+1 or N+2 configurations. And is ideal for powering network transmitters.
Front panel test points and system voltage adjustment pot are provided for fine-tuning output to the requirements of sensitive loads, charging batteries, and to optimize load sharing between Centurion Rectifier shelves.
Local and remote monitoring is provided by alarm contacts which report system off, as well as major and minor rectifier conditions via alarm contacts and front panel warning LEDs.
The Centurion System is engineered for compatibility with NEWMAR’s PFM-400, Power Function Manager to create an integrated power system with metering, alarms, low voltage disconnect and distribution circuit breakers
