LR Series

240 – 300 Watt AC-DC and DC-DC Converters

The LR Series of AC-DC converters represents versatile power

supplies ideally suitable for use in advanced electronic systems.

Features include full power factor correction, good hold-up time,

high eﬃciency and reliability, low output noise, and excellent

dynamic response to load/line changes.

The converter inputs are protected against surges and transients.

An input over- and undervoltage lockout circuitry disables the

outputs if the input voltage is outside of the speciﬁed range. Input

inrush current limitation is included to prevent circuit breakers

and fuses from tripping at switch-on.

The outputs are open- and short-circuit proof.

Full input-to-output, input-to-case, output-to-case, and output to

output isolation is provided. Particularly the outputs exhibit an

extended insulation to the case.
