+5 V/0.3 A (J3-5)
The V
CC
on J3-5 is an auxiliary 5 V regulated power source. It is +5 Vdc +/–5% with
respect to Signal Ground and can supply 300 mA maximum. It is short-circuit-proof, but
if shorted, all outputs will shut down through the Enable/Disable circuitry.
Single Output Power Supplies (Arrays)
Westcor’s standard configuration for single output power supplies is to set the left
module (as seen from looking at the power supply output) as the controlling module of
the array.
