RISH EM 1340 / 30 / 20

RISH EM series measures important electrical parameters in 3

phase and single phase Network & replaces the multiple
analog panel meters. It measures electrical parameters like
Active / Reactive / Apparent energy , power as per models. The
instrument has 2 configurable optional outputs as pulse output
for energy measurement or limit output.

Applications:
Internal Energy billing
Electrical load monitoring
Sub-metering
Genset, Test Benches and Laboratories

Product Features:
True RMS measurement: User Configurable Features:
Measures distorted waveform up to 15th Harmonic. User can select any five or ten measurement
screens which will be shown on display. Also backlit
Energy as per IEC 62053: can be programmed to switched on or off.
Independent Import and Export Energy counter.
Active energy (kWh), Reactive energy (kVArh), LCD Display with Backlit:
Apparent energy (kVAh) measurement. LCD shows 3 Parameters at a glance.
Accuracy as per IEC 62053-21,IEC62053-23.
Parameter Screen recall:
THD Measurement: In case of power failure, the instrument memorizes
The instrument measures THD per phase voltage & the last displayed screen.
current up to 15th Harmonic.
Run Hour, ON Hour, Number of Interruptions:
Onsite programmable: Run Hour records the number of hours load is
Onsite Programmable System Configuration 3PH4W connected. ON Hour is the period for which the
/ 3PH3W / 1PH2W. auxiliary supply is ON. Number of Interruptions
Onsite Programmable CT ratios and PT ratios indicates the number of times the Auxiliary Supply
was interrupted.
Direct remote access(Optional):
Remote configuration of the Instrument via Onsite selection of Auto scroll / Fixed Screen
MODBUS. User can set the display in auto scrolling mode or
Remote access of measured parameters. fixed screen mode locally via front panel keys by
Programmable baud rates up to 38.4kbps. entering into Programming mode or remotely via
MODBUS (Rs485).
Limit (Alarm) or Pulse Relay Output(Optional):
Potential free, very fast acting relay contact. Enclosure Protection for dust and water:
Configurable as pulse output which can be used to Conforms to IP 50 (front face) as per IEC60529
drive an external counter for energy measurement.
Configurable as limit (alarm) switch. Compliance to International Safety standards
Compliance to International Safety standard
Low back depth: IEC 61010-1- 2010
The instrument has very low back depth (behind the EMC Compatibility
panel) of less than 35 mm. Compliance to International standard IEC 61326
