BEL POWER SOLUTIONS INC Switching Power Supply, LRP2320-9B 2 Output 12V, 12.5A, 300 W, Input 125V ac, 90 V ac to 300V

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 boards are coated with a protective lacquer. A temperature sensor generates an inhibit signal, which disables the outputs when the case temperature TC exceeds the limit. The outputs are automatically re-enabled when the temperature drops below the limit. LED indicators display the status of the converter and allow for visual monitoring of the system at any time. The converters can either be plugged into a 19 " rack or be chassis mounted. Two heat sinks of different size and cooling plates for chassis mounting are available.
