LPS203-M Artesyn Technologies Power Supply

The Emerson / Artesyn Technologies LPS200-M Series Power Supplies are compact open-frame designs; measuring just 3 x 5 inches (7.62 x 12.7 cm), with a height of only 1.5 inches (3.81 cm), they have a typical full load efficiency of 88 percent and a power density in excess of 11 watts per cubic inch. The supplies are primarily intended for use in information technology equipment (ITE) and light industrial systems, as well as for equipment intended for non-patient contact and non-patient critical use in low power medical, dental and laboratory applications.

The LPS200-M Series Power Supplies feature a universal 90-264 VAC input - enabling them to be used anywhere in the world - and are also capable of operating from a 120-300 VDC input. The power supply produces a regulated main output, together with an isolated 12 VDC fan output; the latter is rated at 1A, while the main output can deliver up to 125W continuously with convection cooling, or up to 250W continuously with 30 CFM forced air cooling.

Active power factor correction is employed to minimize input harmonic current distortion and ensure compliance with the international EN61000-3-2 standard - LPS200-M Series Power Supplies have a power factor of 0.99 typical. The power supplies have a maximum safety-ground leakage current of 275 µA, and have a main output hold-up time of 16 ms minimum when fed with a 120 VAC input and delivering 250 watts of output power.

The power supplies have a full load ambient operating temperature range of 0 to +50 degree Celsius without de-rating and can cold-start from temperatures as low as -20 degrees Celsius. Between 50 and 70 degrees Celsius, the output should be derated by 2.5 percent per degree.
