This controller is a heavy duty Pulse Width Modulation (PWM) unit. Designed for use with our 4523 and 4524 transformers where the longer flying lines require the higher voltages and if high current motors. It is rated at a maximum of 6 amps or a maximum of 40 volts. Fitted with a phono plug for transformer connection and a phono socket for the ground line connection.
Replacement for the 4541 controller unit.
