Thông số kỹ thuật chính:

1. The transmitter is the power supply device which automatically transmit successive square wave with duty ratio of 1:1 to circuit AB. The power supply procedure is: positive direction-power off-reverse direction-power off. The power supply periods of 4’’,8’’ ,16’’ ,32’’ and 64’’ (also can input 0-996 by hand)are available for option, and external control can be operated by MIPI.

2. Precision of time control: <± 0.005% (controlled by quartz crystal)

3. Rated output power: 5KW (tested at 500V, 10A)

Maximum output voltage: 1000V

Maximum power supply current: 10A (minimum voltage of 200V for AB)

Minimum power supply current is no more than 200mA.

Waveform of output power supply is shown as the following:

4. The instrument has the functions of measuring input voltage, output current and dummy load.

Voltage indication accuracy: ±0.2%±1word

Current indication accuracy: ±0.2%±1word

5. Current memory interval: memory as period interval

6. power supply period：4, 8, 16, 32, 64 seconds can be selected. Also can input power supply period (1-996s) by hand which convenient to research and summarize methods.

7. High-capacity data memory: can store 9000 groups of current data (include the year, month, day, hour, minute and second of the measurement time). It has ac dump protecting function, can store the data for 25 years.

8. Watchdog circuit: the instrument has a watchdog circuit, and hung system will not happen when the device is working.

9. Protective circuit: The device has software and hardware circuit dual overdrive protecting, can replace and prompt in time when the overdrive happens.

10. Temperature of working environment

11. Internal power consumption: 16V, 130mA,

Power supply: 16V, 4.4AH rechargeable lithium battery

12. Volume: 430*260*180 mm

13. Weigh: 10 kg

14. Instrument insulation resistance : >100MΩ
