The three-phase AC standard source is suitable for the measurement department to detect various electrical parameters such as voltage, current, and power meters.

At present, it is mainly used for testing and calibration of digital instruments such as electric energy meters, voltmeters, ammeters, phase meters, frequency meters, power meters, power factor meters, as well as testing and calibration of electrical quantity sensors such as instrument voltage transformers, current transformers, clamp current transformers, and testing and calibration of electrical quantity transmitters such as voltage transmitters, current transmitters, power transmitters, power factor transmitters, frequency transmitters, etc; Testing and calibration of instruments and equipment such as reactive power compensation controllers, power data collectors, on-site calibrators for energy meters, power parameter testers, voltage monitors, distribution load monitors, multifunctional power meters, load management terminals, voltage and current loss timers, and distribution automation terminals.

This three-phase AC standard source is designed using high-precision sampling technology and combined with digital signal processing methods. With advanced technology, excellent performance, small size, light weight and convenient carrying, it can be used both in laboratory and on site.

Main Features

1. Voltage, current, phase, power, power factor, and frequency are all high-precision and high stability standard signal outputs, with software closed-loop.

2. The adjustment of voltage, current, and phase can be performed simultaneously for three phases or any one phase.

3. The phase between three-phase voltages and between each phase voltage and current can be adjusted 360 °.

4. The four states of three-phase four wire/three-phase three wire, positive phase sequence/reverse phase sequence can be combined and output arbitrarily.

5. Adopting an 800 × 600 touchscreen LCD display, it can display 32 types of electrical parameters in real time.

6. There are operation buttons on the touch screen and front panel, and all buttons are clear at a glance. There are commonly used test points for voltage, current, and power factor, which can be easily and quickly operated with just one click.

7. The instant input function greatly simplifies the operation process.

8. It can be equipped with upper computer communication software, and the whole machine can be operated through the upper computer. The communication protocol is open.

9. When there is a voltage short circuit, current open circuit, or wiring error, the output can be automatically stopped and accompanied by an audible and visual alarm.

10. By adopting advanced power amplifier technology, the reliability and stability are greatly improved.
