AC Power Sources
Applications
The TrueWave (TW) is designed for
testing today's complex electronics,
including military and commercial
applications requiring DC and
sine wave testing. The TW is ideal
for testing electronic equipment
for compliance to new European
Standards such as harmonics. Other
applications include: Output Current Per Phase: 13A to MEASUREMENTS
135V in 156V range; 6.5A to 270V in
