XP Power has recently announced its smallest open frame 45W AC-DC power supply. The ECS45 single output power supply measures 50.7 x 76.2 x 26.7mm.

All models have a no load power of less than 0.3 W.

The convection cooled units have efficiency of typically 87%.

A lower profile model, the ECS25 provides 25 W output within the same footprint. They can provide full power output up to + 50 deg C without the need for any external fans or forced airflow and operate up to + 70 deg C with derating.

Both models provide the nominal outputs of +12, +15, + 24 or +48 VDC. The ECS45 is also available with a single +5 VDC 6 A output.

They have a wide input voltage range of 80-264 VAC and are approved for Class I and Class II applications. The units meet UL60601-1 / EN60601-1 medical equipment safety standards and UL60950-1 / EN60950-1 standards for IT and industrial equipment.

They also comply with the EN55011 / EN55022 level B standard for conducted emissions without the need for additional filtering components. Overvoltage, overload and short-circuit protection features are included as standard across the whole range.

Covered versions of each model are also available for Class I installations.

The ECS25/ECS45 are available from Farnell or direct from XP Power and come with a 3 year warranty.
