Product description
This products is used for transmission ,isolation and insulation of voltage signals .The high-level AC voltage signal is converted into a low-level AC voltage signal through the transformer ,and accurately transmitted to the electronic circuit based on microprocessor ,which is suitable for signal acquisition of replay protection voltage products .
Main characteristics

Good linearity and excellent consistency

Good transient characteristics and wide working range

The voltage is directly input and the secondary side directly outputs the voltage;

The circuit is simple ,no external power supply is required and the operation is reliable ;

A variety of form factors are available ,with optional PCB mounting and insert fixing methods;

Application
Apply to system protection and transient analysis of relay protection and automation equipment in power system and high voltage level .
