Transformer speed controller STRS 1 HARMANN for single-phase (230V, 50Hz) motors of rotational devices (fans, pumps).
The housing is made of impact-resistant and UV-resistant ABS plastic in light gray RAL 7035 (up to size 7.5A) or steel sheet in RAL 7032 color.
Surface mounting, degree of protection IP54. Five-step adjustment via a switch on the housing.
The regulator has: a diode signaling the switching on of voltage; built-in thermal protection (TK) – input to which one should connect the terminals of the thermo contact built into the regulated motor; unregulated output (230V / 2A) for controlling an additional indicator, valve or throttle actuator.
No resumption of work after a power failure (manual reset required after the engine failure signal has occurred).
