DESCRIPTION
The GS-R51212 is a versatile triple output, high
current, high voltage step-down switching regulator
module that provides a +5V and two isolated 12V
outputs. It is ideal for microprocessor based boards
because it powers the logic and the communication
ports and it has a Reset output for the correct
system start-up.
The integral heatsink allows a large power handling
capability and it provides also an effective shielding
to minimize EMI.
