RISH OPTIMA VAF
OVERVIEW :
RISH EM 2340DS is Dual Source Energy Meter which measures important electrical parameters of Utility and Generator in 3 phase and single phase network & replaces the multiple analog panel meters. This energy meter is on-site programmable and can measure more than 65 parameters including Active / Reactive / Apparent energy, Power, Total Harmonic Distortion (THD) measurement among others. It is also available with optional RS485 (MODBUS) and Pulse Output options.
APPLICATIONS :
- Energy billing
- Electrical load monitoring
- Sub-metering
- Genset, Test Benches and Laboratories
PRODUCT FEATURES :
True RMS measurement
Measures distorted waveform up to 15th Harmonic.
Energy as per IEC 62053
Independent Import and Export Energy counter.
Active energy (kWh), Reactive energy (kVArh), Apparent energy (kVAh) measurement.
Accuracy as per IEC 62053-21,IEC62053-23.
THD Measurement
The instrument measures THD per phase voltage & current.
Onsite programmable
Onsite Programmable System Configuration 3PH4W / 3PH3W / 1PH2W.
Onsite Programmable CT ratios and PT ratios
Direct remote access(Optional)
Remote configuration of the Instrument via MODBUS.
Remote access of measured parameters. Programmable baud rates up to 38.4kbps.
Limit (Alarm) or Pulse Relay Output(Optional)
Potential free, very fast acting relay contact.
Configurable as pulse output which can be used to drive an external counter for energy measurement.
Configurable as limit (alarm) switch.
Low back depth
The instrument has very low back depth (behind the panel) of less than 35 mm.
Configurable Error Diagnosis Mode
Incorrect phase sequence, phase reversal and phase missing error detection.
LCD Display with Backlit
LCD shows 3 Parameters at a glance.
Parameter Screen recall
In case of power failure, the instrument memorizes the last displayed screen.
Hour Run, ON Hour, Number of Interruptions
Hour run records the number of hours load is connected. ON Hour is the period for which the auxiliary supply is ON. Number of Interruptions indicates the number of times the Auxiliary Supply was interrupted.
Onsite selection of Auto scroll / Fixed Screen
User can set the display in auto scrolling mode or fixed screen mode locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485).
Enclosure Protection for dust and water
Conforms to IP 50 (front face) as per IEC60529
Compliance to International Safety standards
Compliance to International Safety standard IEC 61010-1- 2010
EMC Compatibility
Compliance to International standard IEC 61326
