CEWE ELITE 440 - MULTI LINE 3 PHASE PANEL METER

ELITE 440 - CEWE INSTRUMENT

Elite 440 is a multi-line three-phase digital panel meter for accurate and reliable measurement of electrical  parameters (voltage, current, power, frequency, etc.) for industrial and commercial applications. It has a large multi-line backlit LCD display which enables four parameters to be displayed at the same time.  Modbus communication capability allows easy integration with energy monitoring systems. Expansion modules can be fitted for enhanced system integration (pulse inputs/outputs or analogue output and ethernet).

Applications

1  Commercial   and   industrial  sub-metering  and   energy management (EMS) applications.

2  Building management and monitoring systems  (BMS)

3  High, medium and low-voltage switchgear panels

4  Control and relay panels

5  Power Control Centre (PCC) panels 

6  Motor Control Centre (MCC) panels 

7  Relaying and control outputs

8  Plant automation and monitoring system (SCADA/DAS)

Benefits

1 Easy interface with external devices through built-in Modbus

(RS-485/Ethernet)

2  Detachable connectors for easy installation

3  Diagnostics assistance on display

2   High accuracy: Class 0.2s, 0.5s, 1.0

3   Average THD measurement for voltage,  current and  power, up to 31st harmonic

4  Measurement selection (star or delta/ 3P4W or 3P3W)

5   Modbus communication via RS-485 port/ethernet

6   True root-mean squared (RMS) metering

7   Calibration LED for accuracy test on site

8   Wide and configurable current range 1-2A and 5-10A

9   Wide-range auxiliary power supply, suitable for high-voltage or low-voltage installations

10   Maximum demand recording

11   Midnight snapshot ( values) for selected energy registers

12   Scroll-lock and 'Favourites Page' display support

13   Expansion  capability  via  add   on  modules  for  analogue outputs or pulse inputs/outputs and ethernet

14   Password protection for setup mode

15  Ethernet gateway  module  for easy  integration of multiple meters connected over RS485 network

Note:

Ethernet (add on) module is available for all ELITE 440 models as single meter module or gateway. Additional modules (Two pulse input & output or four analogue outputs) can be available in ELITE 443 to ELITE 448.  #Optional software config view is available for reading and configuration.
