T
he EA, ES and EC Series of line
operated power supplies features
near constant efficiency over the
entire rated input voltage range. These
electrically identical families employ a
highly efficient, closed loop ripple
regulation circuit, which contains a low
pass filter. Each stage, transformer,
filter and regulator is engineered for
maximum efficiency. This combination
provides cooler operation; higher
overall system reliability and greater
line transient immunity to 60 dB, all to
a degree unmatched by conventional
power supply designs. Excellent
thermal management permits full
power output over the full operation
range to +71° with no derating.
The EA and ES Series are plug-in
modules offering a choice of two
industry-standard pin-outs. The EC
Series is a chassis-mount with a topmounted, five-terminal barrier strip for
power entry/exit.
