High-voltage measuring system UPU-22

Also, this device can be called: UPU 22, UPU22.

UPU-22 high-voltage measuring system - adjustable high voltage source AC and DC with integrated gauges, used to diagnose dielectric withstand voltage up to 5 kV DC or AC currents to estimate the leakage current and resistance to the protective earth.

Application: in the development and production of radio and electrical products in research institutes, testing laboratories, repair shops and / or enterprises.

Specifications UPU-22:

Output voltage range:

- DC - from 0 kV to 2 kV;

- AC - from 0 kV to 5 kV.

Error limits installations - ± 3%.

The load current - at least 1 mA.

Leakage current isolation - from 0,05 mA to 20 mA.

Tripping current range - from 101 mA to 140 mA.

The maximum permissible errors current measurement - ± 10%.

Amplitude value of the ripple voltage of 5 kV with respect - no more than 5%.

Failure time of the output voltage of the UPU-22 protection trip - no more than 1 s.

The adjustment range built-in power AC - 10 A to 25 A.

Error limits the internal power AC - ± 5%.

Resistance measurement range of protective grounding - 0,01 ohms to 0,10 Ohm.

Error limits protective earth resistance - ± 5%.

Dimensions - 460x220x480 mm.

Weight - 35 kg.

Principle of the installation of the UPU-22 is based on converting the AC voltage 230 V through the step-up transformer in the DC and AC adjustable autotransformer. At the same time, the resistance measurement is performed using the built-meter and adjustable AC source.

Pressure unit - from 84 kPa to 106,7 kPa (630 mm hg to 800 mm hg).

AC voltage - 230 ± 23 V.

The frequency of the AC - 50±0,5 Hz.

Power consumption units - not more than 700 V·A.

Warm-up time - no more than 5 minutes.

Time of continuous operation - at least 8 hours.

MTBF UPU-22 - not le
