Description
  • Analogue power meter for fast reading of active energy consumption in three-phase lines with or without neutral.
  • Indirect measurement through current transformers.
  • It allows current transformers up to 1000/5 A Easy ratio adjustment in the unit.
  • Analogical display, 7 digits non-resettable.
  • Opto-isolated pulse output communications.
  • LED indicators: power, consumption, and incorrect connection.
  • Allows earth bonding (grounding) of current transformers. See connection diagram below.
  • Accessories: Pulse collector with RS485 ASCII CONTAX NET output (OB708300).
