The NLP250 series offers up to 250 W in a U-Channel power supply. Its form-factor
makes it suitable for use in low-profile applications, such as 1U rack equipment. The
main output channel is compatible with systems that implement distributed power and
point-of-load architectures. It can also be used to power electromechanical devices such
as relays, motors and print-heads. An auxiliary output is also available for those systems
that require "standby" operation. The features of this power supply make it suitable for
use in Information Technology Equipment (ITE) and light industrial systems.
2 YEAR WARRANTY
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated.
