Charging electric vehicle power module REG1K5125G2

ACDC

Product overview
REG1K5125G2 is a Megawatt Charging System (MCS) AC‑DC power module engineered for high‑power EV fast charging with Variable Power Factor (VPF) support for power factor adjustment and reactive power compensation. Designed for 3‑phase AC input (no neutral), it offers a wide PF adjustment range, extensive reactive compensation, high efficiency, high power density and low harmonic distortion. Certifications include TUV CE and cTUVus.
