Powersolve has announced a high efficiency 80 to 150W AC-DC supply that features commercial and medical safety approvals.

The LPS100-M power supply series from Emerson Network Power comprises compact open-frame designs measuring 2in x 4in with a height of 1.29in.

The units have a typical full load efficiency of 88 per cent and a power density in excess of 14W/in.

The LPS100-M is 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 power supply features a universal 85 to 264V AC input and is also capable of operating from a 120 to 300V DC input.

The power supply produces a tightly regulated main 12V DC output, together with an isolated 12V DC fan output rated at 1A, while the main output can deliver up to 8.3A continuously with convection cooling, or up to 12.5A continuously with 30 CFM forced air cooling.

The main output can be adjusted over the range 10.8 to 13.2V DC, and remote sense facilities are provided to compensate for a drop of up to 0.5V between the output terminals and the load.

Active power factor correction is employed to minimise input harmonic current distortion and ensure compliance with the international EN61000-3-2 standard – the LPS103-M has a power factor of 0.99 typical.

The power supply has a maximum safety-ground leakage current of 275uA, and the main output has a hold-up time of 16ms minimum when the supply is fed with a 120V AC input and is delivering 150W of output power.

LPS100-M power supplies are protected against over-voltage, over-temperature and short-circuit conditions, and feature a ‘power fail’ signal for remote monitoring purposes, which will change state at least 6ms before the main output loses regulation.

The power supplies have a full load ambient operating temperature range of 0 to +50C without de-rating and can cold start from temperatures as low as -20C.

The supplies comply with EN55022-B and FCC part 15 Level B EMC standards for conducted noise and meet all applicable immunity standards, including EN61000-4-2, -3, -4, -5, -6, -8 and -11 levels 3.

The power supplies carry a wide set of safety approvals, including UL/TUV/CSA 60950-1 and non-patient contact and non-patient critical 60601-1.
