مولتی متر خروجی RS485 ریشاب Rishabh سری Master مدل RISH MFM 3480 (LCD)

Rish Master  ۳۴۸۰ has touch sensible color graphics LCD display with resolution of 320×240.

It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site locally   by entering into Programming mode or remotely via MODBUS (RS485)

The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A locally by entering into Programming mode or remotely via MODBUS (Rs485)

The secondary of external potential Transformer (PT) can be programmed on  site  locally  by  entering  into  programming  mode  or  remotely  via MODBUS (RS485)

User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire locally    by entering into Programming mode or remotely via MODBUS (RS485). For single phase applications,  single phase version is available.

The instrument has very low back depth (behind the panel) of less than 80 mm in spite of optional features like pulse output

User can set the display in auto scrolling mode or fixed screen mode can be programmed locally by entering into Programming mode or remotely via MODBUS (RS485).

The instrument can detect wrong phase sequence or failure of one of the input voltages and displays “phase” error message.

Active energy (kWh), Reactive energy (kVArh), Apparent energy (kVAh) & Ampere Hour (kAh). Any of the parameters can be freely assigned to 2 optional pulse outputs.

The instrument measures distorted waveform up to 15th Harmonic.

User can suppress the readings below 30 mA in the current measurement by onsite programming if required.

The instrument stores minimum and maximum values for System Voltage  and  System  Current.  Every  ۴۰  sec  minimum  and  maximum readings are updated.

The instrument measures more than 46 electrical parameters of 3 Phase network.

In case of power failure, the instrument memorizes the last displayed screen. The displayed screen will get memorized only if user keeps this screen for minimum 40 sec duration before power failure for fixed screen mode.

Pictorial representation of all 3 Phases (Voltage & Current) in terms of vectors.

Pictorial representation of all  ۳ phases    Current & voltage in terms of sinusoidal waveform.

The instrument can measures per phase (%) THD of voltage and (%) THD of current.

In case of power failure, the instrument memorizes the last energy count.

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.

The optional ModBus output enables the instrument to transmit all the measured parameters over standard MODBUS (RS485).

Customer can assign MODBUS register address as per his need for faster response time.

The instrument can be programmed as Pulse output or Limit Switch.

Pulse Output: The optional pulse output is a potential free, very fast acting relay contact which can be used to drive an external mechanical counter for energy measurement.

Limit switch: The instrument will trip the one or two relays if the programmed parameter exceeds the programmed High & Low Limits.

The  instrument  settings  can  be  configured  locally  by  entering  into Programming mode or remotely via MODBUS (RS485)

Note: The MODBUS communication parameters can only be set locally by entering into the Programming mode.

Ethernet Interface (Modbus TCP/IP Protocol)

The optional Ethernet Interface output transmit all the measured parameters on Modbus TCP/IP. Also user can configure their instrument via Ethernet Interface.

۲  Analog  outputs  can  be  programmed  from  a  list  of  input parameters.
