One unit optimized for fully automatic mass production

PC controlled load simulation and IV curve measurement for solar modules combined with Insulation, Ground Continuity and Diode Tests

The PSL-AU II is designed for integration into fully automatic production systems for high output manufacturing. The voltage and current measurement ranges are fixed according to customers production requirements.
Fast tests for insulation, diode testing and ground continuity as well as options for full insulation and ground continuity can be added optionally. Setup, measuring cycle and procedure instructions for safety tests are controlled via database entries.
