OMEGA's U24Y101 24 VDC Power
Supply provides low cost DC power
suitable for driving process current
loops, transducers, relays, electro-
mechanical timers, and small motors.
All components are rated to insure high
reliablility, and built-in fusing prevents
damage due to short-circuits or
prolonged overloading.
There are two models:
U24Y101 for 120 Vac power;
U24Y101-220 for 220 Vac power
Either model can be converted to the
other by a solder pad change which is
explained below.
