25 WATT
DC-DC
CONVERTER
SVA-SC series
Single Channel
Features
1. Very small (one of the smallest in
Japan)
2. No derating when mounted on a
horizontal surface
3. Low impedance capacitors
4. Over voltage protection
5. EMI: Complies with FCC/A
The SV-series has been developed to follow ETA’s
philosophy of “Miniaturization and high efficiency” of
power supplies. The small size and high efficiency are
suitable for many applications, especially small equipment.
