KST Series IV Measuring Unit

KST Series IV Measuring Unit

The KOPEL KST Series IV measuring unit allows high-speed, high-precision measurement of the IV characteristics of a variety of PV cells.

Overview

COLAR CELL TEST SYSTEM

The light-weight, compact KOPEL KST Series 15 A IV measuring unit is available in two models: the KST-P15Ce standard model, and the KST-P15HC that is specially designed for high-efficiency PV cells. Both models can be connected to and controlled by the PC mounted with a high-performance IV measurement program developed by KOPEL.

Models KST-P15Ce and KST-P15HC are incorporated, respectively, into the KOPEL KSX-1000 high-performance solar cell test system and the KSX-3000H high-efficiency solar cell test system.

KST-P15Ce IV Measuring Unit: Optimum for Both R&D and Production Lines

  • Conforms to IEC 60904-1, JIS C 8913 
  • Compact design incorporating a bias power supply, IV measurement, and PC communication modules
  • Allows measurement of up to 15 A with a 4-range selector
  • Allows measurement of a maximum voltage of ±2 V
  • Sweep directions are selectable
  • High-speed sampling within a measurement accuracy of ±0.2% FS
  • Accurate, high-speed measurement of Isc and Voc at 100 µs/point each
  • Built-in measurement line check function to ensure reliable measurement *1)
  • Combined with a solar simulator, the built-in self-check function allows accurate measurement of dark current *2)
  • Cell classification function, provided as a standard feature, allows classification of up to 16 ratings (More than 16 classes available as an option)

*1)The built-in measurement function detects failures such as a disconnection of output lines and contact failures between the cell setter and probe bars.

*2)The built-in self-check function allows detection and sorting of failed cells prior to IV measurement.
