STRS4 – transformer fan speed conroller with TK, 3×400 V
The STRS4 transformer speed controllers are based on the principle of voltage control with auto-transformers. They are applicable to voltage-controllable motors (400 VAC, 50/60 Hz) to control in 5 steps the rotational speed (of fans, pumps, etc.). They are fitted out with (TK) contacts for thermal motor protection.
- 400 VAC – 50/60 Hz – from 0,5 up to 18 A
- Enclosure: Plastic (R-ABS, UL94-V0, RAL 7035) / sheet steel (RAL 7035, polyester powder coating)
- IP54
- Switch: 5 positions with off-position
- Indicator light
- 230 VAC unregulated output
- Motor protection, by connecting thermal (overheating) contacts of the motor
