DIN rail multi-function digital meter D52-2047, 80-300VAC, cos φ, kWh, W, operation time, 0-100A indirect measurement *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 hole and you are all set. Current measurement does not require any cable stripping or connecting to meter. Current measurement is made with internal current transformer which works the same way as does clamping current meter. In addition to the basic stuff you can monitor power consumption, energy consumption 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. After powering up the the meter it’s internal clock starts ticking and you can view how much energy has been used up and during the time meter was on.

• Changing the display function:
  • Press the SAM CK button (what the fuck this acronym supposed to stand for):
    • Things under green LED indicator:
      • Power factor (cos φ)
      • Operating time (h) (stored into the device's memory in case of power outage)

• Connections:
  • 2x screw terminals for operating voltage and measurement voltage (Voltage measurement is carried out from operating voltage)
  • 10.8mm through hole for passing current sensing wire
• Mounting:
  • DIN rail

NOTE! This meter is not suitable for measuring square wave or corrected sine-wave. This kind of a signal can be found from outputs of many automotive power inverters, some industrial frequency converters, cheap end UPS-systems. According to the manual if you try to measure this type of signals it will destroy the meter.
