Accura 2700/2750

Accura 2700M Accura 2700D Accura 2750P[C] Accura 2750INV/VOL

Accura 2700/2750

Installed at the front of individual motor units, Accura 2750D[C/CI] is connected to Accura 2750P[C] using an Ethernet cable. When measuring the output power of the inverter in the inverter unit, Accura 2750INV/VOL module is installed to measure the inverter output voltage. Accura 2750DCI is connected to Accura 2750INV/VOL, and Accura 2750INV/VOL is connected to Accura 2750PC, respectively, using Ethernet cables. Accura 2750D[C/CI] module collects information on the measurement, protection and operational status of Accura 2750P[C] and Accura 2750LC[I] of the motor-unit via internal communication and provides various information for users through the LCD screen. You can also configure all functions of Accura 2750P[C] and some functions of Accura 2750LC[I] on Accura 2750D[C/CI] module. In addition to Accura 2750D's features, Accura 2750DC provides the RUN and STOP buttons on the front for motor start/stop controls. Along with the functions of Accura 2750DC,Accura 2750DCI provides the INVERTER/BYPASS and AUTO/MANUAL buttons on the front panel for the operation of the inverter.
