Artesyn Technologies offers a series of compact 250 W AC-DC power supplies for use as front-end conversion solutions for systems with distributed power architectures. The NLP250 series power supplies provide a choice of 12 V, 24 V or 48 V outputs to simplify system integration, backed by extensive control and monitoring features to satisfy a wide variety of DC supply requirements.
For distributed power applications, the 24 V and 48 V models are suitable for feeding on-board isolated brick or intermediate bus converters, while the 12 V model can be used to directly power boards fitted with multiple non-isolated point-of-load (POL) DC-DC converters.
NLP250 series has a rugged U-channel construction, combined with highly integrated layout and packaging techniques. This realises a small form factor (102 x 178 mm, 38 mm high), high functionality unit. The main output channel can deliver up to 175 W continuously, or 250 W with forced air cooling. The 12 V and 24 V models are also available with full medical approvals.
All NLP250 power supplies feature a universal 85-264 V a.c. input, and achieve 84% efficiency at full load with a 115 V a.c. input. The 12 V, 24 V and 48 V supplies can provide main channel output currents of 21 A, 10,5 A and 5,25 A respectively. Each supply also features an auxiliary 'always-on' 5 V/1,0 A d.c. output for applications that require standby operation, as well as a 12 V/0,3 A d.c. output for powering fans.
