RS Pro is a compact multifunction instrument which Measures important
electrical parameters in 3 phase 4 Wire and 3 phase 3 Wire Network &
replaces the multiple analog panel meters.
RPM Measurement
The instrument display Rotation per minutes for generator applications.
Number of poles can be set on site depending upon application
requirement.
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 3 Wire 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. Optional
self-powered available, only on either 3 Phase 4 wire or single phase
network are available on request.
Onsite selection of Auto scroll / Fixed Screen
User can set the display in auto scrolling mode or fixed screen mode using
front panel keys.
Optional Pulse Output / Limit switch (Relay output)
Application
The instrument can be programmed as Pulse output or Limit switch.
The RS Pro 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.
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.
Product Features
Limit Switch
The instrument will trip the relay if the programmed parameter exceeds
the programmed Trip Limits.
On site programmablePT / 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.
Optional MODBUS (RS485) Output
The optional Modbus output enables the instrument to transmit all the
measured parameters over standard MODBUS (RS485).
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.
Configuration of Instrumnet via MODBUS
The instrument setting can be configured locally via front panel keys by
entering into the programming mode or rometely via MODBUS (Rs485).
Note: The MODBUS communication parameters can only be set
locally via front panel keys in programming mode.
User selectablePT 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.
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. Measures & Displays Current Demand, kVA Demand, kW
Import Demand, kW Export Demand. Any of the parameters can be
assigned to optional Limit switch.
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.
3 line 4 digits LED display
Simultaneous display of 3 Parameters.

Customer can assign the format for energy
display on MODBUS (RS485) in terms of
W, kW or MW. Additional to this, customer can
also set a rollover count from 7 to 14 digits
depending on the energy format, after which
the energy will roll back to zero.
