Electric safety tester ELABO
PE, ISO, HV

The testing device 92-7G/-7M is concieved for the control via an external PC/PLC. Therefore display and operating devices were renounced. The modular design of the testing instrument permits an optimal adaptation to the individual requirements of the user. Uneeded functions or equipment are omitted. Together with the device ELABO offers an efficient software package.

HV
The high-voltage is produced primarily over an internal electronic HV-source with a high clock frequency and regulated within less 10 ms. Because of the internal source a low residual ripple < 3% (accordingto VDE 0432-1) can be realised, also for DC tests with high currents. The synchronisation can be carried out on an external signal, on the mains frequency or internal (free-running). An electronic voltage ramp mode (voltage ramp up and ramp down) allows for tests of electronic equipment, at which a non-destructive test can only be carried out if the test voltage is increased slowly or for test items with high self-capacitances. The integrated residual voltage measurement assures a safe discharge of thecapacitances of the test items.

Insulation resistance
Insulation resistance measurement with voltages from 500 V up to 8000 V DC at full HV-current are possible. The resistance measurement is carried out together with the high voltage test at the sametime.

PE resistance
Measuring of the PE resistance or the voltage drop at the protective earth conductor through fully electronicregulated programmable test current 10 ... 32 A at an AC voltage of 6 or 12 V.
