Feeder protection relay PAS900 series

over-currentoverloadpanel-mount

PAS900 series digital circuit protection, measureent and control device is a new-generation protection, measurement and control device researched and developed with high-performance DSP digital processing technology. The series product covers low-voltage circuit protection, inlet wire auto-input protection, capacitor proteciton, distribution transformer proteciton, motor differential protection, motor comprehensive protection and voltage comprehensive protection, etc. It is applicable to the protection, measurement and control of circuits, capacitors, distribution transformers, motors, voltage comprehensive, etc. of 35kV and lower voltage level. It can not only be decentralized in switch cabinet and installed on the spot, but also be centralized and installed through screen assembly. (1) Perfect configuration of protection, measurement and control function (2) The design of general software and hardware platforms: It adopt 32-digit high-speed DSP microprocessor, modularized software design and perfect self-check function.(3) General operating circuit: The control power supply DC220V/AC220V for the operating circuit of the device is general, and it meets the requirements of different occasions without changing outlet board; the operating circuit automatically adapts to the tripping and closing current of circuit breaker, and it is flexible and reliable.
