YCS-103 Three-Phase Power Source for Energy Meter Testing
The YCS-103 Three-Phase Power Source is a high-precision,
programmable power source designed for energy meter testing and
calibration. It provides independent three-phase voltage and
current outputs, making it suitable for testing both three-phase
and single-phase electricity meters in laboratories, meter
production lines, and test benches.
