1221C-7401

400A, 72-120V

EV DC Motor Controller

For orders outside of the USA, please, contact us for shipping prices.

This EV DC motor controller provides smooth, silent, efficient and cost effective speed control for on-road electric vehicle applications. This controller utilizes power MOSFET technology to provide benefits unavailable with older speed control systems.

This 1221C-7401 400A 72-120V controller is a high power, heavy duty MOSFET electronic motor speed controller which is ideal for use in electric commuter vehicles, light delivery trucks, and other vehicles utilizing up to 144 volts.

Detailed Specifications

	1231C-8601	1231C-77xx	1221C-74xx
Peak motor and battery current:	500A	550A	400A
Continuous motor and battery current:	500A	550A	400A
Battery voltage range:	96-144V	72-120V

High frequency switching and ultra-low voltage drop provides very high efficiency and quiet operation. Costs, heatsink requirements and motor and battery losses are reduced. Low end toque, range and battery life are increased.
Environmental protection provided by a sealed (factory serviceable), rugged, anodized aluminum extrusion housing. Simple mounting and wiring with push-on type connectors for control signals. Plated solid copper busses used for all power connections.
Thermal protection and compensation circuit provides under-temperature cutback, constant current limit over operating range, and linear rollback in over-temperature. No sudden loss of power under any thermal conditions.
Frequency shifting from 15 kHz to 1.5 kHz at low throttle settings provides improved protection against stalled motors.
Heavy duty power base in 1231C contains additional active devices to improve power handling capability.
Potentiometer fault protection circuitry disables the controller if the throttle wires become open.
High Pedal Disable prevents controller operation if the key switch is turned on while throttle is applied.
Optional heatsink (p/n 16286) for model 1231C controller
improves thermal capability
No adjustments are required.
Simple installation — Uses a two wire throttle potentiometer.
