When the power regulator is operating, the heat will be generated automatically. Please install the system vertically and leave some empty space on two sides to avoid the temperature inside the regulator rising continuously. There must be some ventilation holes on the control box. Please follow the principle of hard air rising to install the ventilation holes or extra cooling fans.Please avoid installing the regulator in a place with high temperature or poor ventilation. Otherwise the maximum operating capacity most be set lower than 70% of the nominal capacity.
Avoid installing the regulator in places with heavy water evaporation, acid, alkaline or corrosive air. Ambient humidity: below 90%RH (no condensation) Ambient temperature: 10°C-45°C
The above numbers are based on the conditions of no corrosion, no greasy dirt, and no cover on the heat sink and following the recommended installation guides based on the principle of heat transfer.
Control & Applied Loading
Phase angle control: continuous phase angle control, steady output, current gauge reading remains steady. But, every halfwave will produce harmonic wave. Applicable loading: fixed resistance loading, variable resistance loading, inductive loading, IR lightbulb.
Zero crossing control: distributed zero crossing control. minimum resolution 1Hz, no harmonic wave, and current gauge reading oscillates. Applicable loading: fixed resistance loading
Wiring & Setup Notices
Standard main circuit setup:
Main Power > Molded Case Circuit Breaker > Contactors > Power Regulator > Loading
The screw must be tightened during the wiring setup to avoid high temperature resulting from bad contact. Once the wiring setup is completed, the front panel and safety cover must be properly installed before the system is powered up to avoid tbe electric shock or short circuit caused by dropped conductive objects.
