AC/DC SWITCHING POWER SUPPLY
INPUT: 170~264VAC
SINGLE OUTPUT
10 WATTS
ERS-SB
General Description
SERIES
ER-Series are open frame, low cost switcher, with high
efficiency. 65 different models are available from low to
medium power. Low power modules use a simple RCC circuit
while higher power supplies employ a forward converter.
