TE’S CROMPTON INSTRUMENTS INTEGRA 1221 DIGITAL METERING SYSTEM

Description

The Crompton Instruments Integra 1221 digital metering system (dms) from TE Connectivity enables cost effective solution for the measurement and display of all electrical parameters including total harmonic distortion (THD) up to the 63rd harmonic.
DISPLAY
High definition screen features programmable backlight for high contrast visibility in low light and direct sunlight applications. The light can be programmed to automatically dim after a set period of time for energy saving.
New “petal” array icons shows the percentage of full scale power of the measured system and the instantaneous power factor (PF) measurement gives clear PF indication. Total power consumption is displayed on the screen at all time.
RJ12 CT CONNECTION WIRING SOLUTION
Integra 1221 dms and the 3-in-1 current transformers include RJ12 plugs and sockets for easy connectivity and installation and the solution is available with wired looms to reduce assembly time and connection errors. IN-OUT voltage connections reduce wiring and installation time.
COMMUNICATION
Modbus RTU (RS485) as standard, two pulsed outputs.
Optional modules available Ethernet (TCP), BACnet and Data Logger.
ENCLOSURE AND SYSTEM
The DIN 96 panel mounted enclosure includes integral panel mounting clips for quick and easy fitting and to suit user requirements, the range includes single-phase, three-phase three-wire and three-phase four-wire capability, all selectable at the point of installation. Optional IP64 kit available.
