Overview
The Altran AEV250-M is part of Altran’s AEV250 contactor family for high-voltage DC switching. Typical uses include charge/discharge switching in battery systems, DC bus isolation, circuit protection interfaces, and power routing in EV, ESS, and industrial control cabinets. The package is compact for panel density and integrates cleanly into new or retrofit DC architectures.
Key features & benefits
- High-voltage DC switching: built for traction, ESS, and fast-charge environments.
- Compact form factor: saves panel space; simplifies cable routing.
- Coil-driven control: integrates with BMS/PLC/VCU digital outputs.
- Application-ready: suitable for charge station, DC power control, and circuit protection schemes.
- Clean isolation path: supports safe pack/bus disconnect strategies.
- Install-friendly: straightforward mounting and mechanical interface.
- Vendor support: detailed specifications and wiring guidance available in the datasheet.
Typical applications
EV & Mobility
Pack main positive/negative switching, charge inlet relays, precharge/ discharge control (with appropriate resistors/logic).
Energy Storage / UPS
Rack/bus isolation, battery string switching, maintenance/service disconnects.
DC Distribution
High-voltage DC panels, industrial DC loads, renewable DC coupling.
Test / Lab
Safe power routing in validation fixtures and power electronics benches.
Selection & integration notes
- Voltage/current margins: select ratings above worst-case DC voltage and fault-level current; consider ambient and duty cycle.
- Precharge strategy: implement precharge resistors/logic for capacitive loads to limit inrush before main closure.
- Polarity & arc path: follow datasheet guidance for recommended polarity/orientation (if specified).
- Coil drive: respect coil voltage/current; add coil suppression per control system best practices.
- Environment: mount to meet temperature, vibration, and contamination requirements.

FAQs
Can I use the AEV250-M for both charge and discharge paths?
Yes—within its rated DC voltage/current and duty cycle. Use precharge for capacitive loads and follow the datasheet’s wiring guidance.
How do I size the contactor?
Allow margin over maximum operating voltage and worst-case current (including transients/faults). Consider thermal environment and duty cycle.
How should I drive the coil?
Provide the specified coil voltage/current. Many systems add coil suppression and economizing; follow the datasheet and controller vendor guidance.
