Product details

Drive module for solar pump duty

It delivers 18.5 kW normal-use output at 38 A, with a heavy-duty rating of 15 kW at 32 A for sustained overload scenarios. Input accepts 380–480 V three-phase, 47.5–63 Hz, and the module is rated IP20 for panel-mount installation in an R3 frame.

Output ratings and duty cycles

Three duty ratings are defined: light-overload (18.5 kW, 36 A), normal-use (18.5 kW, 38 A), and heavy-duty (15 kW, 32 A). Apparent power output is 26 kV·A, matching the normal-use current at 400 V.

Power and thermal profile

Power consumption at full load is 497 W, with standby loss at 37 W — relevant for off-grid solar arrays where idle draw drains batteries. Maximum ambient temperature is 50 °C; operating humidity 5–95 % non-condensing. Sound level 58.8 dB(A) at rated load. The R3 frame includes a control unit and a lithium coin cell (CR2032, 220 mAh) for real-time clock backup.

Control and I/O

Integrated I/O: 2 analog inputs, 2 analog outputs, 6 digital inputs, 3 digital outputs. Communication is via CAN bus — no onboard Ethernet (0 Industrial Ethernet interfaces). For Modbus TCP or PROFINET, a separate fieldbus adapter is required. Efficiency class is IE2.

Frequently asked questions

What does the heavy-duty output rating mean for sizing?

The heavy-duty rating (15 kW, 32 A) is the continuous output under overload conditions — use this for pump starting torque or variable solar input. The normal-use rating (18.5 kW, 38 A) applies to steady-state, non-overload operation.

What communication protocols does the drive support?

The onboard interface is CAN bus only. There are zero Industrial Ethernet ports, so protocols like Modbus TCP, PROFINET, or EtherNet/IP require an optional fieldbus adapter.
