The machinery tester ST400-MT has both an AC high-voltage test 5kV AC, an insulation resistance test with 1000V DC and an earth bond test up to 25A AC. These tests enable the machinery tester to perform electrical safety tests in accordance to EN60204-1.

In case of a change of the test needs, the machinery tester can flexibly, even after the sale, be equipped with other test modules. The adaptation of the test objects can be adjusted by the large selection of different test leads and contacting units to the DUT.

The creation of test sequences is particularly easy through the touch function of the display and can be made more understandable by appropriate images and text.

    • Trip current 0.1 - 100 mA
    • Frequency 45 - 65 Hz
    • Transformer power 500 VA, short circuit current > 200 mA
    • Electronically regulated, incl. ramp function and active discharge
    • Test voltage switched on at zero crossing of voltage
  • ISO-Module DC10-CL:
    • DC Insulation resistance test
    • Test voltage 50 - 1000VDC
    • Resistance measurement 0 - 400 MOhm
    • Electronically regulated, incl. ramp function and active discharge
    • Current limited as detailed in EN 50 191
  • PE-Module AC25:
    • Protective earth test PE
