DESCRIPTION
The VLA124 is an isolated DC-DC converter module.
Its output power is 1.5W and the input is isolated from
the output. The over-current protection circuit is built-in
and it is the best for on-board power supplies, such as
industrial equipment and control equipment.
.
FEATURES
-Input voltage range : 21.6 to 26.4V
-Output : +15V+/-5%, 100mA (output power : 1.5W)
-Isolation voltage strength
4000Vrms, 1 minute (Input to output)
-Low noise
-Built-in over current protection
-ROHS compliance
