Bel Power Solutions LR Series AC-DC & DC-DC Converters

Bel Power Solutions LR Series AC-DC and DC-DC Converters feature full power factor correction, good hold-up time, and high efficiency and reliability. These converters also offer low output noise and excellent dynamic response to load/line changes. The inputs of these converters are protected against surges and transients. An input over- and under-voltage lockout circuitry disables the outputs if the input voltage is outside the specified range. The LR series converters incorporate an input inrush current limitation to prevent circuit breakers and fuses from tripping at switch-on. The outputs of these converters are open- and short-circuit proof. The LR series converters provide full input-to-output, input-to-case, output-to-case, and output-to-output isolation. The outputs offer extended insulation to the case.

Bel Power Solutions LR2320-9 converter features a 240W output power with a 90V_AC to 264V_AC input voltage range. The LRP2320-9 converter features 300W output power with a 120V_DC to 300V_DC input voltage range. The LR series converters' case design allows for operation at nominal load up to +71°C with natural cooling. These converters have a temperature sensor that generates a signal which disables the outputs when the case temperature exceeds the limit. The LR series converters consist of LED indicators that display the status of the converters and allow visual monitoring. These converters are versatile power supplies that are suitable for use in advanced electronic systems.
