12 Pulse Transformers

Engineered for THD reduction, high PF, and synchronized rectifier input in UPS and industrial systems.

12 Pulse Transformers for Harmonic Control & Clean Power

Modern power infrastructure demands high-quality input to safeguard sensitive electronics and meet international harmonic distortion limits. In large UPS systems and power electronics, 12 Pulse Transformers are critical to achieve total harmonic distortion (THD) reduction, improved power factor, and compliance with Customer Standards.

At Rishab Industries, we manufacture & export custom-built 12 Pulse Transformers tailored for rectifier-fed UPS systems, industrial automation, hospitals, and critical infrastructure. With advanced winding configurations and dual secondary arrangements, these transformers provide clean, synchronised, and filtered power for mission-critical environments.
