Industrial and railway inverters, UPS
An inverter rebuilds a clean AC voltage from a battery or a DC bus. It supplies your equipment at 230 V 50 Hz or 115 V 400 Hz, including on board rolling stock.

CAUM.ELEC develops PWM inverters suited to the constraints of each application: battery voltage, waveform, vibration and temperature for on-board use, bypass for maintenance without interruption. We also integrate high-power uninterruptible power supplies (UPS) with their batteries.
- Fixed or on-board inverters, 230 V 50 Hz or 115 V 400 Hz output
- Battery inputs of 48 V, 72 V, 110 V DC and more
- PWM control and control boards developed by CAUM.ELEC
- Manual or static bypass for maintenance without interruption
- Parallel uninterruptible power supplies with battery cabinets
- Service and repair of railway and industrial inverters
