Custom DC and AC power systems
A DC power system keeps your critical equipment running with no break at all: the rectifier-charger feeds the loads and keeps the battery charged, and the battery takes over instantly when the mains fails.

CAUM.ELEC designs and builds complete DC power systems: rectifiers, batteries, protected distribution, monitoring and alarm reporting, integrated in cabinets, enclosures or 19-inch racks. Each system is sized on your power budget and required backup time, from small 24 V supplies to 3,000 A 48 V telecom systems.
- Output voltages of 24, 48, 72, 110, 127 and 220 V DC, or 230 V AC through an inverter
- Modular rectifiers with N+1 redundancy, or thyristor chargers designed by CAUM.ELEC
- Sealed lead-acid, OPzV or Ni-Cd batteries sized for the required backup time
- Distribution through DC circuit breakers or NH fuses, with a signalling contact on every feeder
- Low-voltage battery disconnect, shunt metering, surge protection at the input
- Volt-free alarm contacts and Modbus/JBUS monitoring
- Indoor, outdoor and export versions
