The ABB 3AXD50000707454 is an ACQ80-04-022kW-4 LV AC drive module purpose-built for solar pump applications. It delivers 22 kW normal-use output at 50 A, with heavy-duty and light-overload ratings also at 22 kW (45 A and 48 A respectively). Input is 380-480 V three-phase, 47.5-63 Hz. Frame size R3, IP20 open-type enclosure.
The 22 kW power rating holds across all three duty classes (normal, heavy, light-overload), which is unusual — most drives derate for heavy-duty. Here the current drops from 50 A to 45 A, but power stays flat, so the drive is thermally sized for sustained pump loads. The 35 kV·A apparent power rating confirms it can handle the inrush of a 22 kW motor on start. Standby loss is 38 W — relevant for solar installations where every watt of idle draw cuts into pump runtime. Efficiency class IE2 is baseline for this power band; don't expect premium efficiency, but it's adequate for a pump duty cycle.
Built-in I/O: 2 analog inputs, 2 analog outputs, 6 digital inputs, 3 digital outputs. No onboard Ethernet — the only hardware interface is CAN. For solar pump control that's often sufficient (CAN to a pump controller or SCADA gateway), but if you need Modbus TCP or PROFINET, you'll add an external gateway.
