Radio Design Labs' ST-PD5U is the ideal choice where power distribution from a current-limited switching power supply is needed. It is suitable for powering up to five 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 ST-PD5U 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 ST-PD5U disconnects the load until the condition is corrected.

In system design, various modules are frequently operated from a single power supply. Good engineering practice requires that the power wiring to each module originate at the power supply output. The ST-PD5U serves as the power source for each of five modules. A single ST-PD5U can provide power to RDL’s floating modules. A separate ST-PD5U can provide power to ground-referenced modules. (Do not attempt to intermix floating and ground-referenced modules from a single ST-PD5U.) Note: If using a linear power supply, distribute the voltage to multiple modules using an RDL ST-PD5

Wherever power distribution from a switching power supply is needed, the ST-PD5U is the ideal choice. Use the ST-PD5U combined with other RDL RACK-UP®, STICK-ON®, Flat-Pak™ or TX™ series products as part of a complete audio/video system
