RS Pro
RS Pro
The RS Pro digital panel meters (DPM) have been designed for industrial
applications, which frequently require precise and onsite adjustment of
the display range. It can be used in industrial automation and for
laboratory uses.
Benefits:
• Fast & Easy Installation on panel without any need of external swivel
screws (clip-in mounting for 96x96 size only)
• True RMS measurement.
• 4 Digits ultra bright LED Display (up to 9999).
• On site Programmable CT/PT Ratios.
• User selectable CT Secondary 1A/5A. ·
• User selectable PT Secondary from 60…600 Volts LN AC.
• Wide auxiliary Power Supply which can accept any input between
40V – 300V AC/DC.
User selectable PT Secondary
The secondary of external Potential Transformer (PT) can be programmed
on site from 660…600 Volts LN AC for Voltage DPM using front panel
keys.
• Storage of MIN / MAX values.
Product Features
User selectable CT Primary
The Primary of current transformer can be programmed on site from 1A
to 999kA for Current DPM using front panel keys.
True RMS measurement
The instrument measures distorted waveform up to 15th Harmonic.
User selectable PT Primary
The Primary of Potential transformer can be programmed on site from 60
VLN to 999 kVLN for Voltage DPM using front panel keys.
On site programmable PT/CT ratios:
It is possible to program primary of external potential Transformer (PT)
for Voltage DPM & primary of external Current Transformer (CT) for
Current DPM on site via front panel keys by entering into Programming
mode.
Onsite selection of Auto scroll / Fixed Screen
User can set the display in auto scrolling mode or fixed screen mode using
front panel keys.
User selectable CT Secondary 5A/1A
The secondary of external Current Transformer (CT) can be programmed
on site to either 5A or 1A for Current DPM using front panel keys.
Issue 1.0
4 digits LED display (up to 9999):
14mm ultra bright 4 digits LED display.
Higher Security
Provides Security with user programmable password protection.

Function keys:
Using two function keys it is possible to Display various parameters in
Current and Voltage DPM. These function keys are also used for
programming Password, CT/PT Primary & Secondary values, Reset
min/max values, Auto ON/OFF mode selection.
Screen No. storage
In case of power failure, the instrument memorizes the last screen stored.
For every 1 min. the instrument stores the screen no. in the non-volatile
memory.
Min Max storage of parameters possible
The instrument stores minimum and maximum values. Every 60 sec
stored values are updated.
Low back depth
The instrument has very low back depth (behind the panel) of less than
54mm for 96x96 and 68mm for 48x96 type DPM.
Enclosure Protection for dust and water:
Conforms to IP 50 (for front face) IP 20 (for back) & as per IEC60529.
