Description
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
