Kemo DC pulse converter

By inserting this module, our power controllers (230 V/AC or 110 V/AC) M012, M028, and M028N can be controlled with a DC voltage or pulse width modulation, for example, from microcomputers or PCs. This module is connected instead of the potentiometer. It provides galvanic isolation of the control circuit via optocouplers. The control can be done optionally (at 230 V/AC): DC 1 - 5 V, DC 3 - 12 V, or DC 6 - 24 V. Alternatively, TTL square pulses of 5 V, 1 - 10 kHz, with a pulse width of 10 - 90 % PWM (pulse width modulation) are possible. The regulation is achieved by changing the pulse width.
