How to use

Mount the power supply on a standard DIN rail inside the equipment cabinet and secure the unit according to the manufacturer's mounting instructions. Connect the AC mains input within the 85–264 VAC range to the input terminals, observing correct live, neutral and earth connections. Connect the 48 V DC output to the load, ensuring the current does not exceed 3.2 A. Verify polarities and use appropriate wiring and fuses or circuit protection as required by your installation standards.

Recommendations

Install in a well-ventilated enclosure and maintain adequate clearance around the unit for convection cooling. Avoid exposure to excessive dust, moisture, or temperatures beyond the manufacturer's specified limits. For critical applications, consider using fusing on the DC output and an input surge protector where mains quality is uncertain.
