Industrial battery chargers and rectifiers
A rectifier-charger turns the AC mains into a stable DC voltage: it supplies your auxiliaries and safety circuits, and keeps the battery charged so that it is always ready.

CAUM.ELEC designs its own thyristor chargers: sizing of the transformer, semiconductors and filtering, charge and float voltages set for the battery technology. We also integrate off-the-shelf rectifier modules when that is the most economical solution.
- Charge and float for lead-acid and Ni-Cd batteries, adjusted to the technology
- Three-phase or single-phase supply, mains tolerances taken into account from the design stage
- Ripple filtering for direct supply of the loads
- Cell charging boosters for battery maintenance
- Fault signalling, front-panel metering, alarm reporting
- Repair and refurbishment of existing chargers
