Overview
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 overcurrent 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.
