Usage:
Make sure the electrical installation is disconnected from power before starting the installation.
Attach the power supply to the DIN rail by hooking the top and pressing the bottom until the locking mechanism clicks into place.
Connect the phase conductor (L) and neutral (N) from the 100-240 VAC mains to the power supply input terminals.
Connect the devices to be powered (PLCs, drivers, relays, fans, Arduino/ESP32/STM32 modules) to the DC output terminals, observing polarity (+ and -).
Make sure the total current consumed by all connected devices does not exceed 12.5A.
Ensure a minimum clearance of 25 mm above and below the power supply for airflow and proper cooling.
Reconnect the power and verify that the output voltage is 12 VDC with a multimeter before connecting the loads.
⚠️ WARNING – RISK OF ELECTRIC SHOCK
This product operates at 100-240 VAC. Installation, connection, and any intervention on the input terminals must be carried out EXCLUSIVELY with the electrical installation disconnected from the mains. Connections to the 220V mains must be performed only by authorized personnel, in accordance with the applicable electrical regulations.
