Key specifications

How to use

Install the power supply in a suitable enclosure or panel following local electrical regulations and ensuring adequate ventilation. Connect the AC input to the appropriate mains supply using correct wiring and a protective circuit breaker. Verify polarity and connect the 24 V DC output to the load, observing recommended wiring practices to minimize voltage drop. After wiring, apply power and confirm that the output voltage is within expected tolerance before connecting sensitive equipment.

Recommendations

Operate the unit within its rated temperature and load limits, provide clearance for heat dissipation, and use appropriate fusing on both the input and output sides. For long cable runs, consider larger conductor sizes to reduce voltage drop. Periodically inspect terminal connections and clean ventilation openings to maintain reliable performance.
