Descriptions
The PID insulation tester (TOS7210S) is designed based on the insulation resistance tester (TOS7200) to carry out the evaluation of the PID (Potential Induced Degradation) effect of the PV module precisely and efficiently. Being equipped with the output ability of 2000V and the ammeter with nA resolution as well as a polarity switching function, the TOS7210S is also applicable not only to the PID evaluation but also the evaluation of the insulators that requires a high sensitivity of measurement. The tester is equipped with the panel memory that is externally accessible and RS232C interface as standard; it can be flexibly compatible with the automated system.
Features
- Capable of setting within the range of 50Vdc to 2000Vdc (resolution 1V)
- Ability to switch the applied voltage polarity instantly by the switch on the front panel
- The output is floating from the ground potential.
- Capable of measuring the current value between measurement points.
