Special Converters & Inverters

 Extensive ranges of JDEVS inverters power provide reliable continuous power for

high performance applications. UPS systems are produced in the power range of

5 KVA to 250 KVA based on international standard specifications, and are designed

particularly to meet customer specific demands.
The systems have been configured in a way to protect sensitive loads against the

main disturbances such as, power failures, voltage variations and surge transients,

 spike and frequency variations. PWM-based inverter transforms DC power to AC with

overload capacity for fuse blowing and fault clearance. Heavy-duty design and

out-standing performance of these uninterruptible units help users to avoid of

annoying power problems.

- Configuration as a single/dual load share hot standby mode.
- Three level PWM and vector control technology.
- IGBT based inverter, with high efficiency.
- Analog or DSP control unit.

High voltage power rectifier:
Replacement of Tube Type Rectifiers in 16 Radio Transmission Stations of IRIB
Voltage Rating: 14 ~16 kV DC Power Rating: 400 KW to 3.5 MW
