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 .
