3pMeter: Very small 3 phase power and power quality meter-logger with big memory.

Hardware:

• Small form factor: 35 x 70 x 16 mm.
  fits above a differential switch or a power fuse. There is no need for extra box room, nor DIN rail space in the fuse box
• Easy mounting: power wires I1,I2,I3 are shifted in the holes and voltage L1,L2,L3,N wires are screwed together with the power wires in the cable house.
• For power mains 230-400V+N, 130-230V+N, 130V-230V or mono phase 230V, 50Hz.
• Voltage measurement (Ln-N) up to 300Vac.
• Current measurement (In) up to 125Aac, contact less sensor, hole=5mm (= isolated wire of 16mm2)
• All inputs are protected for lightning pulses of 4000V/20us.
• Contactles communication with PC or mobile phone.
• Logging of power every second for the last 48 h, every minute for the last 40 days, every 15 minute for the last 10 years.

Monitors next mains errors:

• short + long time over voltage.
  
• short + long time voltage dip.
  
• voltage unbalance.
  
• power interruption (also the duration is logged).
  
• huge harmonic distortion.
  
• frequency deviation + frequency jump.
  
• flicker.
  
• over current.
  
The last 1000 errors are saved in memory together with the time and the waveform of L1,L2,L3.

Connections:

• Read out of actual power and power consumption with smart phone via blue-tooth.
• Read out with PC via fast blue-tooth connection.
  
• Advanced presentation software available (includes automatic invoicing and alarming).
