AC Tech MHB420B MC Series Intelligent Drive System

The AC Tech MHB420B MC Series Intelligent Drive System is a 2 HP (1.5 kW) microprocessor-based, keypad-programmable variable-speed drive designed for 400–480 VAC three-phase motors, enabling precise speed and torque control in automated equipment. The drive's 400–480 VAC three-phase input supports typical industrial power distributions, enabling direct compatibility with common motor sizes in manufacturing environments. As a member of the MC Series, the unit consolidates a power board, control board, and an output intelligent power module into a single drive package, simplifying installation and wiring compared with separate components. The MC Series drives are keypad programmable and built for general-purpose variable-speed control of AC motors in industrial settings, with on-board processing that allows parameter adjustments directly from the keypad. In catalog listings, this model is sometimes shown as MH420B, reflecting its MC Series lineage and its 400/480 V input rating. The MHB420B is part of Lenze AC Tech's intelligent drive family, providing an integrated solution for applications requiring reliable speed control and straightforward configuration.
