Yaskawa Electric Corporation E7 Variable Frequency Drive

The Yaskawa Electric Corporation E7 AC Drive with Bypass is an industrial variable-frequency drive that controls AC induction motors with an integrated bypass panel, enabling operation through the drive for variable-speed control or direct across-the-line bypass during maintenance or drive failure. Powered by PWM technology, it accepts 480 VAC, 3‑phase input and provides 0–480 VAC, 3‑phase output with up to 96 A of output current (typical input current around 106 A). The drive offers a 0–60 Hz output range and uses a 3‑contactor bypass system to switch between drive and bypass modes; installation is as an enclosed panel-mounted system. Applications include HVAC systems, pumps, fans, and process-control equipment, with energy savings from variable-speed operation and ensured continuity in critical facilities such as hospitals and large plants. Example model: E7BVB096WU.
