Add to Cart:

The Low Amp Solenoid Driver has been specifically designed to provide optimal pulse width modulated (PWM) control of fuel injectors, high-speed water/methanol valves, and standard flow control solenoids. Each driver unit can control a single unit or batched group of devices drawing 4 Amps or less.


When using PWM to control a solenoid there is a limit to how quickly the solenoid is able to open and close. Below a certain duty cycle the solenoid will never open, and above a certain duty cycle the solenoid will never close. While the opening time is primarily determined by battery voltage, the closing time can vary greatly depending on the hardware being used to control the solenoid. The hardware inside of the Low Amp Solenoid Driver has been designed to minimize the time required for your solenoid to close, allowing you to achieve the maximum possible dynamic flow range from your injection system.

NOTE1: A complete driver (vs. conventional solid state relay) is vitally important to use. Drivers reduce voltage spikes that occur when the actuated device switches off. Such spikes can outright FRY a boost controller or standalone ECU.

NOTE2: This device is intended for intermittent operation and should not be used for applications that require the solenoid to be pulsed at all times when the vehicle is running.
