AC DC Multifunction Tester Calibration , 20A Multifunction Calibrator

Multifunction Calibrator MC30-3A

Main features

1. 5 1 / 2 LED digit displays output, which displays simultaneously by two ways, one bases on actual

value, the other bases on percentage.

2. Use the keyboard to control the increase or decrease of the output. Keyboard control volume is

divided into 100% / N, 10% / N, 1% / N, 0.1% / N (N for 4, 5, 6, 10, 15).

3. The regulator with external control can control the increase or decrease of output, there are

two types of configuration which include keyboard and potentiometer, and they can converse

with each other casually.

4. Output range of AC, DC voltage is 0 ~ 1050V

5. Output range of AC, DC current is 0 ~ 20A

6. AC offers four kinds of output frequency: 50Hz, 60Hz (59.7Hz), 400Hz, 1000Hz, and uses crystal

oscillator to ensure the accuracy and stability of frequency.

7. Output overload is able to protect automatically, and reset manually.

8. In order to reduce beat frequency influence of measured instrument, AC 50Hz output can also

choose to synchronize their electricity.

9. clamp-meter measurement: equipped with standard coil of our factory, 0 ~ 1000A current is

measurable, and margin of error is ± 0.3%.

Technical Parameters

1. Stability: AC < 0.02% / 5 minutes of full range

DC < 0.01% / 5 minutes of full range

Instruments should be preheated for two hours for precision measurement

2. Distortion of AC: <0.5%

3. Ripple factor of DC: <0.05%( rated output)

4. Accuracy of the output frequency: 50Hz, 60Hz (59.7Hz), 400Hz, 1KHz <0.1%

(commercial power synchronization)

5. The range and accuracy of the output voltage, current, as well as the medium resistance (23 ℃ ± 2 ℃,

the value of output is more than 10% of the range)

Attach list

6. Power supply features: AC power voltage 220V ± 10%, the frequency 50Hz ± 1Hz;

7. Working environment: the temperature of working environment is 5 ℃ ~ 35 ℃, relative humidity <80%

8. Working time: continuity

9. Size: 180 × 480 × 480mm3

10. Weight: about 24kg,
