ABB ACS101-K25-I-U AC Variable Frequency Drive

ABB ACS101-K25-I-U AC Variable Frequency Drive is a compact, single‑phase drive designed to control small motors from a 200–240 VAC, 50/60 Hz supply. It draws about 4.4 A on the input (1~) and delivers a programmable output up to 0–300 Hz to the motor, with a continuous output current (I2) of 1.4 A and a max I2 of 2.1 A at 4 kHz switching. The K25‑1 frame provides the 1‑phase ACS101 family and supports switching frequencies of 4 kHz (standard), 8 kHz (low‑noise), and 16 kHz (silent), with motor cables up to 50 m in length. This drive is intended for basic speed control of small motors in industrial settings and is part of ABB’s ACS100 family of compact drives.
