Prozeda Solareg II BASIC HE - Control of Solar Circuit Pump via PWM Signal; Non-Inverse PWM Control; Inverse PWM Control

11
Control of the solar circuit pump via PWM signal
The controller emits a PWM signal at connection O1 for the control of PWM
pumps (jumper position PWM).
Base frequency = 2 kHz, approx. 12 V, approx. 5 mA
- Non-inverse PWM control
Non-inverse PWM control: Target RPM 0-100% equates to PWM 0-100%
