Finding the right power product

For any power product, match the output voltage exactly and choose a rated current or wattage above what the load draws, with margin for derating at high ambient temperature. Check that the input range covers your supply. For backup, decide how long the load must keep running during an outage, then size the battery, charger and inverter together.

Buying guidance

How to choose a power supply

General guidance. Ratings vary by model.

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