Radio Design Labs TX-PD8X
24 Vdc Switching Power Supply Distributor


The RDL TX-PD8X is the ideal choice where power distribution from a current-limited switching power supply is needed. It is suitable for powering up to eight modules from a single power supply. The current limiting circuitry in many switching power supplies will cause the supply to shut down upon power-up when a high current capacitive load is connected. Upon application of power, the TX-PD8X ramps the voltage up, charging any load capacitance as quickly as possible, then switching full voltage to the load. If reverse polarity is connected to the input, the TX-PD8X disconnects the load until the condition is corrected.
