CAPX-P Three-phase Active Power Transmitter
1. Overview
CAPX digital active power transmitter is a device that calculates the active power of the measured current and voltage signals through an internal CPU, converts them into linearly proportional output DC current and voltage, and isolates them. It is equipped with corresponding indicator instruments or devices and is a necessary analog acquisition module for power systems, remote control devices, automation control systems, etc.
