Non Invasive Power Metering


This is a picture of a non invasive power meter for legacy PDUs
  • IP Connectivity via RJ45 to via PH2, H2, H3, E1
  • Measure up to 150 He-Amps via the network
  • +/- 3% Accuracy on Current Measured
  • Multiple Split Cable Collars Provided
  • Current Measure single phase 0.1A to 60.0A
  • Single Phase Only
  • Used for Legacy PDU applications & on site tonging

 Brings monitoring functionality to non-intelligent PDUs (Power Distribution Units)
 Local monitoring is via a two digit LED display
 Cable collars supplied to support: 8mm, 10mm, 12mm, 13mm, 14mm, 15mm, 16mm & 18mm diameter cables
 Current measuring range 1.0A to 60A
 Measured supply range: 90V AC ~ 250V AC
 Frequency: 50Hz ~ 60Hz AC
 12V DC power supply @ 60mA (typically supplied direct from PH-2, UT-H2, UT-H3 & UT-E1
 Direct RJ45 connection to the UT-H2, UT-H3 & UT-E1 monitoring units via an RS232/RS485 communication protocol
 Can be calibrated to cable types to typically provide ±3% accuracy amp current readings

An open fork in the HE-Amp enables it to be placed directly over a power cable and a choice of locking-ring collars, to suit most international 13A, 16A and 32A cable sizes, are provided. Each locking-ring separates into two halves and is placed around the power cable and pushed into the HE-Amp clamping bore, retaining the cable with a neat twist and lock action. A very lightweight (135g) and compact device (134mm x 88.5mm x 41mm), it is designed to be installed at any convenient location on the cable.

Software Provided to Graph Current

The Software can measure up to 150 x HE-Amps (or 150 x PDUs) and 300 x temperature &/or humidity sensors
