ITR 1.5 Amp – Speed Controller – Systemair – WAS KNOWN AS STL 1.5
Controls the speed of single phase (230 V AC – 50/60 Hz) voltage controllable motors through phase angle control.
There is a potentiometer and a separate ON/OFF switch with built-in telltale and the minimum speed allowed can be adjusted using an internal trimmer (factory pre-set = 100V). The terminal board has a supplementary connection to bypass the ON/OFF switch (automatic start) or to branch off 230V not controlled (3 wire motor connection, valve, lamp, damper, etc…)
There are two working modes, internally selectable by placing or removing the red jumper on the PCB.
Hard Start – The motor will always start (or restart) at maximum speed for 8-10 seconds; after that the motor speed automatically follows the position of the potentiometer.
Normal Start – The motor starts according to the position of the potentiometer.
The IP54 case allows use in the most demanding environments.
Maximum ambient temperature 35°C
Current rating – 1.5A
