Rish Delta Power

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.

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.

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.

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.

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).

3 line 4 digits LED display

Simultaneous display of 3 Parameters.

Enclosure Protection for dust and water

Conforms to IP 50 ( for front face) & IP 20 (for back) as per IEC 60529.

EMC Compatibility

Compliance to International standard IEC 61326.
