Drive for solar pumping — ratings that match the load profile
The ABB 3AXD50000707287 is an active-production LV AC drive module for solar pump applications. It delivers 4 kW output power at 9.4 A in normal use, with a heavy-duty rating of 3 kW at 7.2 A and a light-overload curve of 4 kW at 8.9 A.
Input power and environmental limits
Runs on 380–480 V three-phase, 47.5–63 Hz — covers standard global mains. Maximum ambient temperature is 50 °C, and the operating humidity range is 5–95 % non-condensing. The IP20 open-type enclosure means it is intended for inside a panel, not direct outdoor exposure.
Built-in I/O and communications
Includes 2 analog inputs, 2 analog outputs, and 6 digital inputs plus 3 digital outputs — enough for a basic pump controller with pressure transducer feedback and start/stop commands. Communication is via CAN; there is no onboard industrial Ethernet port, so if the site requires PROFINET or EtherNet/IP, an external gateway or option module is needed.
Power consumption and standby loss
Rated power consumption is 140 W under load, with a standby loss of 15 W — useful for estimating panel heat load and off-grid solar battery drain when the pump is idle.
