PLH Series DC Power Supplies: Compact Case Size

Higher Power Density and Better Energy Efficiency

The PLH series achieves an exceptional power density for a linear regulated power supply by offering in excess of 90 watts from a case just 107mm wide (quarter rack 3U).

This gives it an unusually small bench footprint taking up less space on a crowded bench. For rack-mount application, up to four units can be mounted into a single 3U slot.

Power efficiency and near-silent cooling

Despite its small size and linear regulation, the PLH series generates relatively little heat through the use of an advanced phase controlled pre-regulator. This gives it significantly higher energy efficiency than conventional linear regulated designs, particularly when supplying lower voltages. The internal heat-sinks use fan-assisted convection cooling in order to remove the heat with minimal fan noise.
