Connecting multiple RDL modules to a single power supply has been made easier with the introduction of the TX-PD8X Switching Power Supply Distributor. Designed for use with a current-limited switching power supply, the TX-PD8X can distribute power from the supply to 8 RDL modules with a total load of up to 2 Amps.
Current-limited switching power supplies have a tendency to shut down upon power-up if a high current capacitive load is connected. The TX-PD8X avoids power supply fold-over during power-up by ramping up the voltage, charging any load capacitance as quickly as possible, then switching full voltage to the load.
External ON / OFF control of the TX-PD8X is possible by dry contact or open-collector using a variety of RDL products including:
(8 cables included)
To further simplify life, the TX-PD8X ships with 8 connectorized power cables. Each cable is 1 meter in length.
