Solenoid Driver

Our medium-amp Solenoid Driver is a solid state relay (SSR) that's been specifically designed to provide optimal pulse width modulated (PWM) control of high-speed solenoids and fuel injectors. Each driver can provide progressive control for multiple high-speed solenoids or fuel injectors with a total current draw of 20 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. Hardware inside of the Solenoid Driver has been designed to minimize solenoid closing time. This broadens the maximum possible dynamic flow range from an injection system. Tuning is easier and system functionality is enhanced.

NOTE: 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.
