Elite 300 Secure Meters

The Elite series is a multi-line three-phase digital panel meter for reliable and accurate true-RMS measurement of electrical parameters (voltage, current, power, frequency etc.), for industrial and commercial applications. It is available in two display types, LED display (Elite 100) with MODBUS communication, pulse output or alarm output as an option.

It has a unique pass through mechanism for current terminations which makes installation simple. The advantages of this pass through mechanism for current measurement are

  • No more risk of CT wire opening
  • No lugs required – reduces overall cost
  • No wire cut – reduces overall cost
  • Minimal burden
  • No screw tightening required during connection – which often damages the screw head
