Tiny, low profile, 150W AC-DC power supply from XP Power

The EPL150 series from XP Power, is a range of high density, low profile, open-frame AC-DC power supplies that are aimed at space-critical, cost-sensitive, industrial, ITE and healthcare applications.

The series produces 100W output with convection cooling and 150W with as little as 10CFM airflow. The product has a 101.6 x 50.8mm footprint and its low profile of 25.1mm makes it suitable for space-constrained applications. Class-leading power density is enabled by high efficiency, up to 95% typical at 150W with better than 85% achieved down to 10% load. No load losses are less than 0.5W giving reduced running costs and compliance with the latest environmental goals and legislation.

The parts are approved for use in Class I or Class II (earth free) applications for highest flexibility.

The EPL150 series features comprehensive safety agency approvals including IEC60950-1-1 for ITE, IEC62368-1 for ITE and IEC/ES60601-1 for medical.

Medical approvals are for two means of patient protection (2 x MOPP) from input to output and one means of patient protection (1 x MOPP) from both input to earth and output to earth, suitable for BF applied-part applications. Patient leakage current is less than 50µA and isolation test voltage is 4kVAC, input to output and 1.5kVAC from input to earth and output to earth.

Low-noise outputs available are 12,15, 18, 24, 28, 36 and 48V with a useful additional 12V fan supply provided, rated at 0.5A. Input is 80 – 264VAC and operating altitude maximum is 5000m making the parts suitable for worldwide use.

Full power is available to +50°C with derating to +70°C ambient temperature with comprehensive protection included for overvoltage, overload and short circuits.

The EPL150 series is intended for use in many industries including automation and process control, broadcast, ITE, oil and gas and medical where the combination of small size, efficiency, performance and safety approvals will be attractive.
