Three Phase 500V 120A Programmable Voltage Source RS232

GF303D Three Phase Programmable voltage source and current source for power meter & power factor meter

GFUVE is a leading manufacturer of three phase portable meter test equipment for electricity meters and energy meter testing and calibration in China, we supply stationary or portable test equipment, power sources, reference standards, calibrators.

The GF303d three phase Programmable voltage source and current source consists of an integrated three phase current and voltage source(up to 500V/120A or 500V/20A) and built-in three-phase electronic reference standard of accuracy class 0.05%. Characteristic features of the GF303D are its wide measuring range, high accuracy and high tolerance to unwanted external influences. The equipment offers high functionality combined with an excellent menu guided operation via built-in keyboards and colored 7” touch LCD-display.

GF303D portable Programmable voltage source and current source adopts mature signal synthetic and advance power amplifier technology, wide voltage and current output with high efficiency and high stability, to be widely used in lab and field.Our phase angle adjustable multi-channel programmable power sources are either constant current mode or constant voltage mode power sources. They are equipped with functions to adjust the output amplitudes, output frequencies, output phases, output enabled/disabled, open/closed loop control through PC via either RS232 or IEEE-488.2 interfaces.

APPLICATION

It 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.

Nation-level utility companies
Governmental bureaus of metrology
Energy meter manufacturer

FEATURES

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
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 ~ 63times of the amplitude and phase harmonics, and it can be added to the base wave in every harmonic output
Range switching automatically
To use software calibration, simple operation, stable and reliable
Display of vector diagram, adjustable to IEC387 OR DIN410, IEC60736
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
