STL4410 series ground bond tester is used to measure the internal grounding resistance of electrical equipment. It reflects the (contact) resistance between the exposed conductive parts of the electrical equipment and the total grounding terminal of the electrical equipment.
** Standard Lead Time: within 4 weeks **
Test current: 1.00-45.00A, 1.00-32.00A
Grounding resistance range: 0-600mΩ
Four-terminal test mode to ensure test accuracy
The internal power amplifier circuit drives the current output, which is not affected by the power supply and load
The output holes on the front and rear panels are designed to facilitate the integration of standard chassis
999.9 seconds test time, which is greater than common 60S test requirements
Safety lock function to prevent the instrument from accidentally opening the test state
