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)
