Details:

The ACE4 inverter is a controller suitable for AC Induction motors, in the range from 15 to 25 kW continuous power, used in a variety of battery powered material handling trucks.

It can be supplied in two configurations:

standard version, with a 23 poles connector
premium version, with a 35 poles connector, enhanced I/O.

The high number of I/O accommodates a large number and wide range of vehicle controls and sensors.

It can easily interface with a wide range of external device via CAN Bus.

Double microcontroller reduntant safety architecture.

Typical applications include, but are not limited to: Counterbalanced trucks with load up to 8 tons, HLOP (Vna), GSE, Tow tractors and airport ground support vehicles, Aerial (telescopic boom and scissor lift) access equipment.
