Sub-1U distributed-power converters deliver 250W

The Astec NLP250 series 250W AC/DC power supplies deliver compact and convenient front-end conversion for distributed power architectures.

Dimensions of 10.2cm x 17.8cm x 3.8cm, suitable for 1U-high rack systems, combine with a choice of 12V, 24V or 48V outputs to simplify system integration.

The 24V and 48V models are suitable for feeding isolated brick converters or intermediate bus architectures, while the 12V model can be used to directly power boards fitted with multiple non-isolated POL DC/DC converters. Typical conversion efficiency is 86% at 230V AC input. Each unit also provides an auxiliary ‘always-on’ 5V DC output for applications that require standby operation, as well as a 12V output for powering fans.

Maximum surge-current capability is 130% of the rated steady-state current for 500ms, which also makes the NLP250 series suitable for powering capacitive loads or electromechanical devices such as relays, actuators, motors and print-head solenoids.

Available variants include versions for industrial applications, as well as medical power supplies approved to UL/cUL2601-1 and VDE EN60601-1. The medical versions also have 140µA ground leakage for extra safety, and include fuses in both live and neutral inputs.
