Rish Master 3440 - Class 0.2s

Active Energy - Class0.2S as per IEC 62053-22

Energy measurement

Active energy Import (kWh),Active energy export (kWh) Reactive energy Inductive(kVArh),Reactive energy capacitive(kVArh), & Apparent energy (kVAh). Any of the parameters can be freely assigned to 2 optional pulse outputs.

Auto Energy Ranging Count on Display

The Energy count rollover from WATT to KWATT then to MWATT has energy increases over the period.

Programmable Energy format & Energy rollover count

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 9 digits, after which the energy will roll back to zero. The above settings are applicable for all types of energy.

Total Harmonic Distortion (THD)

The instrument can measures per phase THD of voltage & current, and it also measure individual 31st harmonic of voltage and current(Display on Modbus only).

Wide Auxiliary Supply

It can accept Input from 100 VAC/DC to 550 VAC/DC

Wide Input Voltage Measurement

Measurement wide range of input voltage 100VLL to 600VLL.

User selectable CT Secondary 5A/1A

The secondary of external Current Transformer (CT) can be programmed on site to either 5A or 1A locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485)

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 locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485).

User selectable PT Secondary

The secondary of external potential Transformer (PT) can be programmed on locally via front panel keys by entering into Programming mode or remotely via MODBUS (RS485).
