The Powertester PwT 1500 at CAiRS is the first system installed in Hong Kong and the only machine that does automatic power cycling, by powering the modules tens of thousands, potentially millions, of cycles while simultaneously producing analytical data for real-time failure-in-progress diagnosis.  Therefore, it can reduce total testing time of up to 10x.

It provides thermal transient measurement for junction temperature characterization and Rth identification following the JEDEC JESD 51-1 static test method and support the JEDEC JESD51-14 transient dual interface measurements.

It can conduct power cycling test in accordance with IEC 60749-34:2011 to meet the requirement of ECPE Guideline AQG 324 Qualification of Power Modules for Use in Power Electronics Converter Units in Motor Vehicles.
