Description

In order to ensure personnel electrical safety, the output circuits are galvanically isolated from the power supply. The voltage on the DTE-20M output terminals is less than 7V with fully opened thyristor, that is favorable for the circuit breakers contacts in time of tripping, which wear-out is significantly reduced during multiple tests.

Technical specifications

Power supply voltage* 380V ± 10%
Power supply frequency 50 Hz ± 1%
Maximum consumption current 140 A
Maximum voltage at output terminals 7 V
Maximum current at output terminals (rms) 20 kA
Maximum DTE-20M power consumption 120kW
** Output current measuring and recording range with measurement error less than 3% 20—20000 A
Measuring and recording range of output current duration with measurement error less than 1,5% 0,01—1000 sec.
Temperature protection threshold 96°С ± 10%
Overall dimensions,(mm) 720х485х880
Weight of the device without the flexible bars 86 kg max
Device average service life 10 years

* Possible DTE-20M power voltage is 220V, wherein the maximum output current – 13kA).

** Technical specifications correspond to reduced values for device operation with a single-phase voltage regulator
