CalSource P-350 – Three-Phase Calibration Source
The CalSource P350 is a high-accuracy three-phase calibration source engineered for testing and calibrating voltmeters, ammeters, power and energy meters, and power factor meters. It independently generates and controls three voltages and three currents with programmable frequency (45–65 Hz), low THD [1% ] and precision better than ±0.2%. A vibrant colour LCD, continuous digital POT control, and RS-232 PC interface ensure user-friendly operation. The P350 also features advanced energy meter calibration modes—automatic, semi-automatic, and manual—making it a versatile solution for both production line and field calibration work.
