Description

The 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. 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 TX-PD8X serves as the power source for each of eight modules. The TX-PD8X normally provides power to ground-referenced modules. A front-panel switch permits the installer to enable external control. When the ON terminal is connected to ground, the TX-PD8X outputs are active. External control is possible using RDL detection or control modules, open-collector outputs from OEM equipment or controllers, or using a D-RT2 RDL remote wall control. The front-panel blue LED remains illuminated when the outputs are active.
