Electronic speed controller STL5 0.2-5.0 A

Electronic speed controller STL5 from 0.2 - to 5 amps, ideal for the control of fans and ventilators.

The electronic speed controller of the STL series controls the speed of single phase, through voltage controllable motors (230 Vac - 50 Hz), by changing the supply voltage using a phase angle control. A potentiometer and a separate lighted on/off switch is integrated. The slowest allowed speed can be set internally by a small trimmer (factory setting = 100 V). The connecting plate has an additional connection to circumvent the ON/OFF switch (automatic start), or to branch uncontrolled 230V (three-wire motor connection, valve, flap, etc.)

There are two operating modes, internally selectable by adding or removing the red jumper on the STK.

1. "Hard" start: The motor will always start (or restart) at the max. speed for 8-10 seconds, afterwards the motor speed will adjust automatically to the position that is determined by the potentiometer.
2. "Normal" start: The motor starts according to the position set by the potentiometer. The IP 54 housing permits the use as well in demanding environments.
