The essential quantities of an electrical system are measured, and read out in a clear-cut fashion at 5 displays.

• Accurate measured values:
  U, I: 0.2     P, Q, S, PF, meter: 0.5%       F: 0,02 Hz
• 4-quadrant measurement of all values in AC systems
• Clip-on extension module with average value and load profile recording, RS-232/485 interface, MODBUS, synchronizing input, switchover of high/low tariffs
• Safe 3-way galvanic isolation between all circuits
• 2 outputs for pulse or limit values
• 4 meters for active power: Incoming/outgoing with high/low tariff*
• 4 meters for reactive power:
  Inductive/capacitive or incoming/outgoing with high/low tariff*
• All counter values, recorded values, and settings are kept on a power supply failure
• System/application: Single-phase 3L balanced/unbalanced (Aron, Full), 4L balanced/unbalanced (Open-Y, Full)
• Dimensions 144 x 144 x 46 mm
• 4-digit, 14 mm high LED display
