Electrical safety tester
PSE GmbH has developed an electrical safety test that combines different tests for the testing of PV modules. With our four-in-one tester it is possible to test the following according to IEC 61215-2 and IEC 61730:
- Wet leakage current test (MQT 15 IEC 61215-2)
- Insulation (dielectric withstand) test (MST 16, IEC 61730)
- Ground continuity test (MST 13, IEC 61730)
- Reverse current overload test (MST 26, IEC 61730
We place great value on comfort and flexibility during the design of this tester. The predefined test procedures in the software lead into an easy adjustable tool without losing the flexibility for user-specific testing. The documentation fulfills the requirements of standardization bodies according to accreditation. All important test parameters are recorded and stored via the test stand’s graphical user interface.
