EC series 301

Three phase input-single phase output, double conversion, regenerative, VFI, MPWM, IGBT, microprocessor based UPS with galvanic isolation for comprehensive power protection.

Designed and built for the harsh Indian power conditions, EC-series models provide dependable, premium quality regulated power even under highly fluctuating input voltage and frequency.
(Converts the generator output into clean, computer network grade, highly regulated power supply.)

The UPS is also capable of delivering highly demanding surge loads without performance derating. EC-series offers superior levels of protection against all input power related problems and provides regenerated clean network grade high- quality power to the connected loads.

Apart from being an Online UPS, it also provides international levels of voltage and frequency stabilization, and also acts as power conditioner.

Galvanic isolation via transformer (as per IEC62040) eliminates problems associated with common mode noise, neutral and earth potential drifts which can cause irreparable loss.

Complies with international standards.

We were awarded "The best in class" award for our Online UPS in range of 20KVA-60KVA by Soft Disk for the year 2010.
