6V-90V 15A PWM DC Motor Speed Controller - 0-5V PLC Analog Regulator Module

The 6V-90V 15A PWM Controller is a panel-mount speed regulator designed to control the rotational speed of brushed DC motors and other inductive loads across a wide 6V to 90V operating range. It generates a pulse-width-modulated output with a duty cycle adjustable from 0% to 100%, allowing smooth speed control from standstill to full motor RPM without the power loss of a linear regulator. The controller accepts either a local potentiometer input or an external 0–5V analog signal, making it directly compatible with PLC outputs, microcontroller DACs, and industrial automation systems. Its 15kHz PWM frequency (listed as 16kHz on some distributor variants) keeps switching noise above the audible range and supports a maximum controlled power of 1000W, with a 15A fast-blow ceramic fuse providing overload and short-circuit protection. Reverse-polarity protection and over-voltage protection are built in, and the quiescent current is only 0.005A in standby. The module measures approximately 64mm × 59mm × 28mm and uses terminal blocks for power-in and motor-out wiring. This DC motor speed controller is suited to PWM motor speed regulator applications in DIY robotics, model vehicles, small power tools, industrial conveyors, brushless water pumps, and cooling fans, where a compact 15A DC motor controller with flexible analog control is required.

Application

1. DIY robotics and model vehicles requiring compact variable-speed motor control.
2. Small electric tools such as drills and grinders with brushed DC motors.
3. Industrial automation for conveyors, mixers, and material-handling equipment.
4. Pump and fan systems needing continuous flow or airflow adjustment.
5. PLC-integrated control cabinets using a 0-5V analog speed command signal.
