100-150 W AC-DC supply

Emerson Network Power has launched a 100-150 W AC-DC supply that features both ITE and non-patient contact and non-patient critical medical safety approvals.

The LPS103-M is a compact open-frame design that has a typical full load efficiency of 88% and a power density of 0.9 W.

The supply is primarily intended for use in information technology equipment 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 device has a universal 85-264 VAC input enabling it to be used anywhere in the world and it can operate from a 120-300 VDC input. The supply produces a tightly regulated main 12 VDC output, together with an isolated 12 VDC fan output; the latter is rated at 1 A, while the main output can deliver up to 8.3 A continuously with convection cooling, or up to 12.5 A continuously with 30 CFM forced air cooling.

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