The VRA_D-5W & VRB_D-5W Series are
specially designed for applications where a
wide range input voltage power supplies are
isolated from the input power supply in a
distributed power supply system on a circuit
board.

1) Where the voltage of the input power supply
is wide range (voltage range: ≤ 2:1);
2) Where isolation is necessary between input
and output(Isolation Voltage ≤ 1500VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

All the VRA_D-5W Series have been tested
according to the following recommended testing
circuit before leaving factory. This series should
be tested under load. Never be tested under no

If you want to further decrease the output ripple,
you can increase capacitance properly or choose
capacitors with low ESR. However, the
capacitance should not be too high. (Table 1).
*Dual output models unbalanced load: ±5%.
**Test ripple and noise by “parallel cable” method. See detailed operation instructions at Testing of Power
Converter section, application notes.
Note:
1. All specifications measured at TA=25°C, humidity<75%, nominal input voltage and rated output load
unless otherwise specified.
2. See below recommended circuits for more details.
