Product Description

Principle

This product uses a current type Voltage transformer. The primary side is connected with a current limiting resistor in series in the circui to convert the high voltage milliampere current,  which is converted into milliampere current on the secondary side through the intermal magnetic core.The resistance is connected in parallel for sampling or through the circuit amplifier.This product is widely used in multifunctional electronic energy metes,anti-theft meters,digital display maters,etc.It can also be used in digital instruments and meters such as power transmitters,telemetry and remote control data acquisition systems,relay protection,etc.

* Using high magnetic permeability ultra-microcrystalline iron core
* Working temperature range: -40°Cto +75°C
* Pure copper enameled wire has high winding precision and good linearity
* Epoxy resin potting with high pressure resistance level
* Small size, strong anti-interference ability
* Altitude does not exceed 1000mRelative humidity: ≤95°
* All plastic shell, flame retardant conforms to UL94V-0
* Conform to JB/T 10667-2006,JG 314-2010
