PID Insulation Tester, Model Name/Number: Kikusui Tos7210s, 50 V Dc - 2000 V Dc

Product Details

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 2000 V and the ammeter with 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 the arbitrary setting of the output voltage You can set the test voltage that is applied to the circuit within the range of 50 V DC to 2000 V DC(resolution 1 V). In addition, an insulation resistance test of the electricity/electronic components or the electricity/electronic devices is also possible besides the voltage specified in JIS C 1302:1994. In the range of 50 V to 1000 V, the output properties are complied to JIS C 1302:1994. Polarity switching functionYou can easily change the output polarity by the switch on the front panel. The PID deterioration is a reversible phenomenon that may recover after the reverse bias voltage is applied. The polarity switching is a convenient function that can avoid a wiring change that connects to the DUT. In addition, switching by the external control through the RS232C interface is also possible.The output is floating from the ground.The output terminal is floating from the ground electric potential(*1). In addition, a shielded cable is adopted as an output cable (TL51-TOS). Therefore, it can be measured only an electric current flowing between test points excluding the one between the DUT and the ground, and it realizes to conduct the highly-sensitive and precise evaluation.*1: Ground voltage of the terminal that polarity is set as an anode (± 1000 V dc)Ground voltage of the terminal that polarity is set as a cathode (+1000 V dc and -3000 V dc)Analog output terminalIn the resistance display mode, the voltage depending on the measured resistance is logarithmically compressed and output within the range of 0 V to 4 V. In the current display mode, the current is output in a linear scale depending on the measured current and ranges of measurement (4 ranges). You can analyze the changes or the deterioration status of the DUT by using an external recording device such as the data logger.
