World’s smallest 45 W ‘green’ power supply has medical and industrial safety approvals

by donpedro

XP Power announced what is believed to be the world’s smallest open frame 45 W AC-DC power supply. Setting a new benchmark at this power level, measuring just 50.7 x 76.2 x 26.7 mm (2 x 3 x 1.05 inches), the ECS45 single output power supply is 25% smaller than the current industry standard of 2 x 4 inches. All models have a no load power of less than 0.3 W, helping the end equipment comply with internationally recognized energy efficiency standards. In addition, these convection cooled units are highly efficient, typically 87%, resulting in less waste heat to dissipate. The lower profile ECS25 model provides 25 W output within the same footprint. They can provide full power output up to + 50 degrees C without the need for any external fans or forced airflow and operate up to + 70 degrees 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.
The power supplies suit designers of medical, IT or industrial equipment.
Applications can cover a wide variety, such as broadcast equipment, computing and data storage. The medical safety approval makes it suitable for products such as portable medical devices, home healthcare devices and personal drug delivery equipment.
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.
