GF303D portable 3 phase ac Electrical Power Calibrator with 500v voltage and 120a current source
GF303D portable 3 phase ac Electrical Power Calibrator is suitable for power department, measuring department, quality
control department, research units, and institutions of higher
learning, and electric energy meter, power distribution terminals,
power supply management, load control, power quality, reactive
power compensation device and the production of enterprise etc.
GF303D is electric AC/DC power and energy calibrator for
calibration of power meters, power transducers, power quality
analysers and generally all kinds of power measuring devices. AC
voltage, current, power and energy functions have calibrated phase
shift in frequency range from 40 Hz to 70Hz with resolution as good
as 0.001 Hz.
The GF303 AC Power Calibrator is equipped with RS232 PORT as
standard communication interface to control external devices
remotely. Power Factor Validation Power factor is an important
element when users judge the efficiency of a device.
In the Power Calibration mode, the GF303D can be used as a source
to calibrate DC and single-phase AC watt meters, power analyzers,
and energy meters. In this mode, the output voltage can be set up
to 500V, the output current up to 120A, and the power factor from
-1.0 to +1.0 lead/lag in the frequency band from 40Hz to 70Hz.
FEATURES
- To set up and take the load regulation of voltage, current, phase
angle ,frequency and power factor etc; as a large current source,
voltage source and power source
- To set 2 ~ 51 times of the amplitude and phase harmonics, and it
can be added to the base wave in every harmonic output
- Voltage, current output a wide range, big power, high stability,
waveform distortion degree is small
- Strong with load ability, but it can take capacitive, sensibility,
resistance of composite type load or load and load regulation is
higher than 0.01%
- To apply the 32 bit MPU + DSP + CPLD, powerful flexible
- To use hardware PID, fast response, the change of load will not
cause output volatility
- Industrial frequency waves as high as 5000 points a week of the
wave kneading, signal output without filter, precise output
waveform, the harmonic output precision, harmonic distortion degree
is small
- Range switching automatically
- To use software calibration, simple operation, stable and reliable
- Display of vector diagram, adjustable to IEC387 OR DIN410
- Big touch screen, 7-inch TFT color LCD display, English interface,
operating simply
- To have perfect over-current, over-voltage, heat, a
shorts-and-opens, overload protection, failure detection
automatically
- With RS232 interface, and PC connection
- To take place machine software, it can be output through the PC
software program
