TP4CH 3 Phase 4 Wire Smart Meter


TP4CH 3 Phase 4 Wire Smart Meter

Category: 3Wire



TP4CH 3 PHASE 4 WIRE SMART METER is a 3Phase Energy Meter that measures 4 different loads (4 in 1 energy meter) with Modbus RTU enabled. Supplied with 100A or 400A Split-Core Clip On CTs ( 3nos x 4 channel). It is compliant to IEC 62053-21 “Static meters for active energy (Class 1 & 2)” and IEC 62053-23 “Static meters for reactive energy (Class 2 & 3)”.


  • Each of the 4 channel has an independent high-precision energy metering chip, to ensure metering accuracy and reliability.
  • 4 quadrant energy measurement; each channel can measure both import energy and export energy with nett energy calculations.
  • Electrical parameters measured by each channel includes V, I, F, PF, kW, kVAr, kVA.
  • Able to record and alarm events like undervoltage, overvoltage, voltage spike, phase loss, etc.
  • Reading closing date can be set to enable automatic bill settlement for each month.
  • Timed data freeze, hourly data freeze and daily data freeze. Meter can freeze data of energy, etc. There are 30 timed freeze, 254 hourly freeze, 62 daily freeze.
  • LCD digital display, loop display of various parameter (of each channel).
  • Data from meter can be read by handheld unit (IR port) and thru RS485 interface.
  • Compliant to standard 35mm din rail installation.
