Buying guidance
How to choose a power supply
General guidance. Ratings vary by model.
- Output voltageMatch the output voltage to the rating on the equipment label or datasheet, for example 12 V or 24 V DC.
- Current with headroomAdd up the current of every device on the supply and choose a rating above the total. Check the derating curve.
- MountingDIN rail for control panels, enclosed for cabinets, open frame or PCB mount inside equipment, adapters for single devices.
- Environment and approvalsCheck the operating temperature range, the IP rating for outdoor or dusty sites, and the approvals in the datasheet.
