MC0-250 1000V 250 kW Traction Inverter / Motor Controller

High-performance 1000V 250kW traction inverter and motor controller for electric vehicles, mobile robotics, aerospace, marine, and industrial EV programs. MC0-250 targets a smaller liquid-cooled package while retaining high-voltage architecture, CAN/J1939, and Automotive Ethernet support.

Voltage: 1000 VDC
Power: 250 kW
Current: 250 ARMS
Switching: 100 kHz
Volume: 2.4 L
Mass: 3.5 kg

Best fit

1000V EV and machine programs that need a smaller controller than MC0-500 but still want high-voltage architecture.
Integrators evaluating passenger EV, robotics, aerospace, marine, or industrial platforms where package volume and mass are tight.
Teams that want to start integration planning before production availability and need public docs plus direct engineering review.

Applications

Use the application list as a starting point for fit checks. Steinmetz will review motor, pack, cooling, environmental, safety, and production requirements before recommending a configuration.

Passenger electric vehicles and high-performance conversions

Track, drift, and motorsport EV builds

High-power mobile robotics and autonomous machines

Electric mining and construction equipment

Light aircraft, drones, and aerospace demonstrators

Electric marine craft including foiling, patrol, and passenger vessels

Integration proof package

How to read these ratings

MC0-250 is marked as shipping Q3 2026; contact Steinmetz for current sample timing, production status, and validation roadmap.
The 250 kW, 250 ARMS, >99% nominal efficiency, and thermal behavior should be reviewed against actual bus voltage, motor, coolant, ambient, and duty-cycle requirements.
Safety, EMC, and vehicle-level compliance need to be reviewed in the context of the full installation and the latest Steinmetz validation package.

Why this matters against incumbent controllers

A 2.4 L, 3.5 kg package gives teams a smaller 1000V option for programs that do not need MC0-500 output.

Shared 0-Series interfaces and documentation help integrators plan one controller family across multiple platform sizes.

Early RFQ/application-review flow helps teams lock cooling, connectors, motor feedback, and control-interface requirements before launch timing gets tight.

Frequently asked questions

What cooling method does the MC0-250 use?

The MC0-250 uses liquid cooling. Final thermal performance depends on coolant type, flow rate, inlet temperature, pressure budget, mounting, motor operating point, and duty cycle.

What high-voltage connectors are compatible with MC0-250?

The MC0-250 is planned around Powerlok 300 Series connector architecture. Confirm the latest connector and harness details with Steinmetz during design review.

What control interfaces does MC0-250 support?

The MC0-250 is planned to support CAN with SAE J1939 and Automotive Ethernet 100BASE-T1 for communication and control.

Which motor types are compatible with the MC0-250 traction inverter?

The MC0-250 is designed for three-phase AC motors commonly used in EV powertrains, including permanent-magnet synchronous motors (PMSM/IPM) and induction motors. Send motor, sensor, voltage, current, speed, and cooling requirements for fit review.

What is the current availability status for MC0-250?

MC0-250 is listed as shipping Q3 2026. Contact Steinmetz for current development status, sample availability, production timing, and whether MC0-500 is a better fit for near-term programs.
