DIN rail multi-function digital meter D52-2048, 80-300VAC, W, VA, cos φ, 0-100A indirect measurement with external current transformer *new*

DIN rail mounted multipurpose voltage meter and current meter, which can be used in industrial or home environment. Just connect two leads to your voltage supply / desired phase, which is found in your electrical cabinet (or that particular place you want to measure or monitor) and put a cable you want to measure for current through the external current transformer and you are all set (with the prediction that you have connected the coil). Current measurement does not require any cable stripping or connecting to meter. Current measurement is made with external current transformer which works the same way as does clamping current meter. In addition to the basic stuff you can monitor apparent power and power factor (cos φ). As an example this extra readout gives you the ability to predict upcoming maintenance need, monitor appliance performance or just to see how much is the supply load.

Meter technical details:

• Operating voltage range:
  • 80-300VAC
