Power supply rack for climatic cycling test
One essential part of the module quality testing according to IEC 61215 are the thermal cycling test (MQT 11) and humidity freeze test (MQT 12). Beside the environment simulation in the climate chamber it is necessary to energize the PV modules during specific parts of the test.
Beside the energizing it is necessary to monitor each single module temperature, the ambient temperature as well as the humidity during the test.
We at PSE AG have developed a power supply and data acquisition system which is able to work with any market available climate chamber.
The power supply rack is delivered with up to 10 single power supplies, data acquisition system and sensors to energize and monitor the modules during the thermal cycling tests.
The software which is delivered with the system automatically checks for the validity of the ambient parameters activates the power supply in the correct moments of the test and reports any deviations.
Optional, an electrical isolated rack for the installation of the PV module inside the climatic chamber and a UPS (uninterruptable power supply) to continue the measurements during electrical break down, can be ordered with the equipment. For accredited test laboratories we offer ISO 17025 certification for all relevant components.
