RISHABH Rish Delta VAF

RISH Delta VAF DL 10

Application:
RISH Delta Energy 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.

Salient Features:
• Fast & Easy Installation on panel with self clicking.
• True RMS measurement.
• Pulse / Limit Switch (optional).
• 3 Line 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 100 VLL to 500 VLL.
• User selectable 3ph3wire / 3ph4wire / single phase Network.
• Wide auxillary Power Supply which can accept any input between 40V – 300V AC/DC.
• Storage of MIN / MAX values.
• Measurement & Display of RPM, Run hours, On hours, No. of interruption.

Products Features:
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.
