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. All PCB boards are coated with a protective lacquer.
With over 80 years designing, manufacturing and supplying power supplies for some of the most demanding applications, Gresham has a strong reputation for service and support.
