Technical specifications

Applications and selection

Use this model for 5V DC logic, embedded electronics and compatible LED modules, after checking the equipment input specification. Its DIN rail format suits organised control cabinets and panel-building projects.

Size the supply from the total running load, starting current and cable voltage drop. Allow suitable capacity margin and apply the manufacturer’s temperature and input-voltage derating curves.

Installation notes

• Installation, mains wiring and protective earthing must follow the manufacturer’s instructions. Check the mechanical drawing and terminal arrangement before replacing an existing unit.

Common questions

Can I replace another 5V supply with this model? Match the output type, voltage, load current, mounting space and connections; a similar wattage or series name alone does not establish compatibility.

Can it power LED strips? Only use strips designed for 5V DC, within the available current and power after derating. Never connect a mains-voltage strip to the DC output.
