How to use
Mount the unit on a standard DIN-rail inside a control cabinet or panel. Connect the AC mains supply within the specified 85–264 V AC range to the input terminals, observing correct phase and protective earth wiring. Connect the 12 V DC output to the load using suitable wire cross-section and secure terminal screws. Ensure the total connected load does not exceed 30 W and verify polarity before powering sensitive devices. Allow adequate ventilation around the unit and avoid installing next to heat sources.
Usage recommendations
For reliable long-term operation, maintain ambient temperature within the device’s specified operating range and keep the ventilation paths clear. Use fuses or upstream overcurrent protection sized for the installation, and consider adding an input filter or surge protection in environments with unstable mains. Periodically inspect terminal connections for tightness and check for signs of overheating when the system is under load.
