Multifunctional electronic power meter 4DA
 Multifunctional 4DA electronic power meters of active and reactive energy operated through current and power transformers. Use 4DA1 multifunctional meters for direct connection, and 4D multifunctional meters without instantaneous measurements.
The 4DA multifunctional power meter operates in three- or four-wire circuits, with optional sensors of reverse, neutral current, CT short and bypass. The multifunctional power meter includes two programmable relays.
The profile is recorded in the multifunctional poweer meters through 8 programmable channels of 2,880 events each, sufficient for monthly recording in 15-minute intervals. The event log is sufficient for 500 incidents.
The multifunctional meter's LCD output is programmable from about 80 values structured in main and sub-menus.
Communication options for the multifunctional power meter include RS-485, one- or two-way PLC, and modem.
The 4DA multifunctional power meter measures all instantaneous per-phase values, temperature, overload, over- and under-voltage. Refer to the specifications for full list of the multifunctional meter's features.
