Delta Energy

Availability: In Stock
Weight: 0.00kg
Dimensions: 0.00cm x 0.00cm x 0.00cm

The Delta Energy is a low cost multifunctional quality instrument measures important electrical parameters in 3 phase 4 Wire and 3 phase 3 Wire Network & replaces the multiple analog panel meters. It measures electrical parameters like AC Voltage,AC Current, Frequency, Active, Reactive, Apparent Power, Import & Export Energy & many more.

On site programmable PT/CT ratios
It is possible to program primary of external potential Transformer (PT), primary of external Current Transformer (CT) on site via front panel keys by entering into Programming mode.

User selectable CT Secondary 5A/1A
The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A using front panel keys.

User selectable PT Secondary
The secondary of external Potential Transformer (PT) can be programmed on site from 100VLL to 500VLL using front panel keys.
User can set the display in auto scrolling mode or fixed screen mode using front panel keys.

Onsite selection of Auto scroll / Fixed Screen
User can set the display in auto scrolling mode or fixed screen mode using front panel keys.

Low back depth
The instrument has very low back depth (behind the panel) of less than 55 mm(Without output option).

Four function keys
Using the four function key, it is possible to go desired parameter screen instantly.

True RMS measurement
The instrument measures distorted waveform up to 15th Harmonic.

RPM Measurement
The instrument display Rotation per minutes for generator applications. Number of poles can be set on site depending upon application requirement.

Optional Pulse Output / Limit switch (Relay output)
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 relay if the programmed parameter exceeds the programmed Trip Limits.

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

Configuration of Instrument via MODBUS
The instrument setting can be configured locally via front panel keys by entering into the programming mode or remotely via MODBUS (RS485).
Note : The MODBUS (RS485) communication parameters can only be set locally via front panel keys in programming mode.

3 line 4 digits LED display
Simultaneous display of 3 Parameters.

Storage of parameters possible
The instrument stores minimum and maximum values for System Voltage, System Current, Run Hour, ON Hour & number of Interrupts. Every 60 sec stored values are updated.

Energy Measurement (Import & Export)
Active Energy (kWh), Reactive Energy (kVArh), Apparent Energy (VAh). Any of the parameters can be assigned to optional Pulse output.

Energy Count Storage
In case of power failure, the instrument memorizes the last energy count. Every 1 min, the instrument updates the energy counter in the non-volatile memory.

User selectable 3 phase 3Wire or 4Wire or Single phase Network
User can program on site the network connection as either 3 Phase 3 Wire or 4 Wire or single phase network using front panel keys.
In case of self powered Rish Delta only either 3 Phase 4 wire or single phase network are available.

Demand Measurement
Measures & Displays Current Demand, kVA Demand, kW Import Demand, kW Export Demand. Any of the parameters can be assigned to optional Limit switch.

Enclosure Protection for dust and water
Conforms to IP 50 (for front face) & IP 20 (for back)
IP 65 (for front with seal) as per IEC60529.

EMC Compatibility
Compliance to International standard IEC 61326.
