PWM Power Module
with Negative Signal Trigger
(Fully Assembled Unit)

Product Use

This OKA PWM Power Module is especially developed for Automotive use.

OKA PWM Modules are Pulse Width Modulation power modules for powering resistive loads such as Incandescent Lamps or Heaters, as well as Inductive loads such as spring loaded Solenoid Valves or Motors.

OKA PWM Modules are designed to be controlled by a 3 to 5 Volt PWM signal pulse from microcontroller and control high voltage (up to 50VDC) and/or high current (up to 20A) load.

OKA PWM Modules can switch loads at any frequency from from DC to 1KHz.

When low voltage PWM signal is applied to the control input of the OKA PWM Module with Negative Trigger the Output is mirrored (Inverting Output).
