SVB-SC SERIES
Features
50 WATT
DC-DC
CONVERTER
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 suppliesThe small size and high efficiency are
suitable for many applications, especially small equipment.
