AKGrad32 Specifications: Powerful Power Regulator controlled with reliable Fieldbus
The 32bits DSP of the AKGrad32 measures and calculates true RMS mains voltage V, current A, power kW and resistor OHM for each phase.
This powerful measurement system enables:
► Patented soft-start firing for any inductive downstream transformer which avoid over current peaks even in cost saving 2-Phases Control Three Phase Circuit.
► Unique integrated power saving “SYNCHRO” feature for real-time load management and energy bill reduction.
► Very high precision closed loop kW-%-I²-U² regulation with partial/total load failure diagnosis on each phase.
► Instantaneous adaption to voltage variations, over currents due to short circuit to ground or load surge.
► Phase-Angle soft start for heaters with high cold/hot variations with current limit feature.
It offers the following features as standard:
► 5 digital inputs,
► 3 output relays,
► 3 analog inputs mA/V,
► 3 analog outputs mA/V,
► Modbus RS232/485/422 connection,
It offers the following options:
► Profibus-DP and/or Modbus-Ethernet,
► Ethernet/IP and /or Profinet I/O,
► Modbus RS232 HMI panel operator.
