GF101 PROGRAMMABLE SINGLE PHASE PHANTOM LOAD POWER SOURCE

The GF101 AC power calibrator is equipped with RS232 port as standard communication interface to control external devices remotely. In the power calibration mode, the GF101 programmable phantom load power source can be used as a source to calibrate single-phase AC watt meters, power analyzers, and energy meters. In this mode, the output voltage can be set up from 0 to 1000V, the output current from 0 to 200A, and the power factor from -1.0000 to +1.0000 lead/lag in the frequency band from 40Hz to 70Hz. Power factor is an important element when users judge the efficiency of a device. It is suitable for power department, measuring department, quality control department, research units, institution of higher learning, electric energy meter, power distribution terminals, power supply management, load control, power quality, reactive power compensation device and production of the enterprise and so on. It can be as single phase voltage source, current source and power source.
