Power Frequency AC Withstand Voltage Test Transformer Systems , Power Frequency Intelligent Control Unit

I. Product Description :

DSC series power frequency test intelligent control units, is carried out by the IPC with PLC control, and set the operation, control, monitoring and protection in one of the intelligent control system.

The unit is not only monitoring the test parameters of test objects, but also monitoring the status of their own. When there is any suggestion that the fault may be, the system immediately is protected for strengthening the security of test. Signal transmission in the system is done by the optical fiber instead of the original cable, which achieves isolation between the main portion and control portion; especially the electrical isolation between the host computer and the operator to ensure the safety both for the operator and for the test system.
