Security and safety are key! We use best-practice cybersecurity management according to established standards, we stay up to date and vigilant!

Powerful flexibility

The ACH comes in two sizes: Medium and Large and both versions are available in the 350 V - 650 V or 450 V - 850V range.

ACH35M30 and ACH65M30

ACH M

Inmotions ACH M is a family of inverters/motor controllers with power levels from 100 to 250 kVA, designed for nominal voltages between 350 V and 700 V. The ACH is developed with traction, hydraulic pump and generator applications in mind which makes it an ideal choice for hybrid or battery-powered electric vehicles and machines,

ACH35L70 and ACH65L50

ACH L

The ACH L is based on the ACH M and is scaled up to power levels from 150 to 400 kVA, designed for nominal voltages between 350 V and 700 V. The ACH L is developed with traction and generator applications in mind which makes it an ideal choice for hybrid or battery-powered electric vehicles and machines where high power levels are required.
