The PWM (Pulse Width Modulation) connector provides energy savings and extends the life of the coil. Connector receives the full supply voltage for the solenoid. After the elapsed time, the circuit will reduce the full voltage to a lower voltage to save energy. This lowers the coil temperature, thereby extending its service life. Power reduction is achieved with pulses with adjustable output voltage modulation.

The installation of the jumper (bridges) allows the desired energy saving settings to be achieved.

If no bridge is installed, the greatest amount of energy savings is achieved. (PWM signal = 1 × On, 8 × Off)
When all three jumpers are installed, the power saving is the least. (PWM signal = 8 × On, 1 × Off)
