3-Phase AC Standard Source 750V / 25A

Harmonic Standard Source 2..31

Accuracy: 0.05

Capable of calibrating all kinds of indicating instruments such as DC meters,AC meters, phase meters, frequency meters, power meters, power factor meters, multimeters, energy meters and electric measurement transducers, etc

Automatic calibration mode and manual calibration mode are  built-in of KS833.

These built-ins are high precision standard sources that respectively  relate to voltage, current, phase, power factor and harmonic

Capable of outputting standard voltage, current, phase, active power, cross-phase reactive power and true reactice power, make use of software to realize closed loop control on all outputs guaranteeing its low drift and its annual stability

Current generator provides the function of open-circuit protection and open-circuit alert in itself

Can freely output 2-31 times harmonics, including: Standard output at Grade 0.1 for 2nd-19th harmonics, and satandard output of Grade 0.2 for 20th-31st harmonics.

Large LCD display, all English pop-up menus for these operations

rotary encoder operation

slight-touch keyboard operation

operation under PC Windows System

Built-in RS232 port, allows software upgrade without opening up the external box of the equipment; and calibrated data can be uploaded into PC computer at users’ convenience

The shock and impact resistance external box is made of high intensity aluminum alloy

reliable high-power heating radiator units, the equipment is durable to use
