HYBRID IC
VLA301-243R
ISOLATED TYPE DC-DC CONVERTER
DESCRIPTION
The VLA301-243R is a DC-DC converter. Its output power is
3W 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:63 to 156V DC
•Output: +24V, 130mA (output power : 3.1W)
•Thin-profile and lightweight design
•Isolation between input and output : 2000Vrms, 1min
•Built-in over-current protection circuit
APPLICATIONS
On-board power supplies for control equipment.
