Overview: This document provides technical specifications for various models of single-phase speed controllers and electromechanical speed regulators used in professional ventilation systems.

Power Supply: All models operate on a single-phase power supply with a voltage range of 220-240Vac at 50/60Hz, except for models FE230 and FE1023, which support a wider voltage range of 85-265Vac at 50Hz.

Maximum Load: The maximum motor load varies across models, with FE229 and FE230 supporting up to 4.5A, FE263 and FE282 up to 8A and 10A respectively, and FE1023 up to 10A. The maximum load for lights is 5A for most models, except for FE230 and FE1023, which support 2A.

Control Features: Models FE229, FE263, and FE282 use bipolar switches and rotary knobs, while FE230 and FE1023 feature a digital keyboard with 5 keys. The speed controllers (FE1037, FE1040, FE1041) offer 3, 4, and 5-speed switches respectively.

Dimensions and Weight: Dimensions range from 128x88x73 mm to 310x235x130 mm, with weights varying from 0.31 kg to 7 kg.

IP Protection: IP ratings vary, with most models having IP50 or IP56 protection, except for FE229 which has IP55.

Additional Features: All models include trimmers for adjusting minimum and maximum speed. Protection fuses are rated at 10A T or 16A F, depending on the model. Thermal contact is available in specific versions (FE230/T and FE1023/T).

Motor Type: All models are designed for single-phase induction motors, with variations in speed control capabilities.
