Key specifications

How to use

Mount the QUINT-PS on a standard DIN rail inside a control cabinet, ensuring adequate clearance for ventilation. Connect the three-phase AC supply within the specified 320–575 V range and verify correct phase sequence and grounding according to local electrical standards. Connect the 24 V DC output to the load, observing polarity and load capacity limits. Perform initial commissioning checks for output voltage under no-load and rated-load conditions. Use appropriate wiring and overcurrent protection consistent with system design and safety regulations.

Recommendations

Install the power supply in an environment that meets rated temperature and humidity conditions, provide sufficient airflow around the unit, and avoid mounting near strong heat sources. Verify that upstream protective devices (fuses/breakers) and downstream distribution follow the equipment requirements. Regularly inspect connections and terminal tightness during preventive maintenance to ensure continuous, reliable 24 V DC supply for control and automation systems.
