DRT electronic fan speed controller DIN
The electronic speed controllers of the DRT series control the speed of single phase (230 Vac
- 50 Hz) voltage controllable motors by varying the supplied voltage through phase angle
control. These controllers are modules designed to be built in on DIN-rail in control panels
or switchboards. To power on, an external switch on the power supply is needed, a control
potentiometer (470 kOhm, not included) can be easily connected on terminal blocks. A
supplementary terminal block is foreseen to branch off 230 Vac not controlled for 3-wire
motor connection, a telltale or to control a valve or damper.
There are two working modes, internally selectable by placing or removing the red jumper
on the PCB.
1.'Hard'start: The motor will always start (or restart) at max. speed for 8-10 seconds, after
that the motor speed automatically follows the position set by the potentiometer.
2. Normal start: the motor starts according to the position set by the potentiometer.
□ FEATURES
• Power supply: 230 Vac 50 Hz
