Compliance West CDT240 Capacitor Discharge Tester For Functionality Tests, 8A. Optional 15A





Monthly: POA

The Compliance CDT 240  Capacitor Discharge tester  offers engineers a much simpler and quicker way to perform the  IEC Testing of residual voltage after plug disconnect ( 50Hz & 60Hz sources) compared to the traditional method of performing the test. In addition the Capacitor Discharge Tester is lightweight and compact for those labs where space on the test bench is at a premium. 

The CDT-240 disconnects the line at the voltage peak and analyzes results to the requirements of various Standards, allowing quick results.

There is even scope for viewing decaying waveforms.  Multiple built in pre-sets are available on the unit for standards EN61010, EN60065, EN60950, EN60601-1 and EN6033 but customers may also edit the pre-sets if they would like.   The Compliance West CDT-240 offers an enjoyable and hassle free testing experience.
