INT-2270-M-01 Crompton The Integra 2270 Power quality meter
CROMPTON INSTRUMENTS INTEGRA 2270 POWER QUALITY METER
INTEGRA 2270 POWER QUALITY METER
Power to analyse quality, with a touch
The new Integra 2270 Power quality meter monitors - The quality of incoming electricity with a 0.2S% accuracy of reading
- Total Harmonic Distortion – the total distortion in the supply, measured as harmonics of the base frequency up to the 63rd harmonic.
- Waveform Capture – allows instantaneous events to be captured and analysed offline using a computer.
- Voltage Interference – known as ‘sags and swells’. Variations in the voltage supply caused by non-linear loads, as described BS EN 50160:2010.
Key features
Signal conditioning
Patented* technology enables measurement of power quality within any voltage of electrical supply, in a single product, covering the global range 120/230V of electrical supplies.
Inputs and output
- Total measurement for all utilities in a single meter, including measurement of pulses from water and gas meters.
- Can be configured to communicate outputs relating to active and reactive energy to building management systems
- Alarms can be configured for any relevant, measured parameters and can also serve as a trip function
Full colour touch screen display
Energy-efficient and intuitive touch screen display with clear graphics and simple navigation. Easy for Field Engineers to set up and configure, reducing site time and saving money during installation.
Easy installation
Plug and socket connectivity for easy installation of prewired looms, saving valuable installation time and reducing wiring errors. Current flows directly through the meter primary CTs, meaning there is no need to terminate the CT wire at the meter.
The Integra 2270 digital meter provides measurement, isolation and conversion of all main electrical parameters and can be used in single-phase and three-phase three-wire unbalanced, four-wire balanced and unbalanced systems. RS485 Modbus RTU communications protocol, pulse/alarm outputs and inputs are fitted as standard.
