40kW 50kW Compact EV Charger Power Module 17.2kg 84x300x437.5mm Lightweight Quick Maintenance Design

The 40kW and 50kW units are the compact steps of the family and are the usual choice for destination chargers, retrofit projects and cabinets with limited rack space. Both share the 84mm x 300mm x 437.5mm envelope and 17.2kg weight class with the 60kW and 80kW units.

Small footprint. At 84mm wide, 300mm deep and 437.5mm high, the module fits a narrow rack and leaves usable space for DC busbar, control harness and airflow. In a compact cabinet the difference between a module that fits and one that does not is usually a few millimetres of width, which is why the family keeps a single envelope across all four ratings.

Lightweight handling. 17.2kg is within one person handling limits, so a single technician can seat the module into the rack, and a field replacement does not need a second pair of hands or a lifting aid. On an assembly line the same weight class allows common jigs and torque procedures.

Service access. The module withdraws forward from the rack, so a replacement is done from the cabinet front instead of from the side or the rear. That matters where cabinets are installed in a row against a wall or in a parking structure with limited clearance.

Upgrade path. Because the envelope is shared with the 60kW and 80kW units, a cabinet built around a 40kW module can be populated with a higher power step later without changing the rack, the mounting kit or the cabinet sheet metal.

Older DC chargers often fail on module availability rather than on cabinet condition. Because the input window covers 260Vac to 530Vac and the output window covers 1000VDC to 1500VDC, the module can be specified into retrofit builds where the existing cabinet, busbar and cable schedule stay in place and only the power stage is replaced.

For a mixed fleet of installed cabinets, keeping one 40kW or 50kW module per service van covers the majority of call outs, and the shared envelope means the same spare fits a 60kW or 80kW cabinet when the site has been upgraded.

• Mckee-40 at 40kW for compact and space limited cabinets
• Mckee-50 at 50kW for destination charging and retrofit projects
• Mckee-60 at 60kW for mainstream public fast charging cabinets
• Mckee-80 at 80kW for high power corridor and fleet charger builds
• Bulk supply for charger OEM assembly lines and distributor stock

• Compact destination chargers at hotels, offices and retail parking
• Retrofit and power upgrade of installed DC charging cabinets
• Cabinets with limited rack space or restricted service clearance
• Charger OEM assembly lines needing a common module envelope

Confirm the cabinet rack dimensions against the 84mm x 300mm x 437.5mm envelope, the DC busbar interface and the site input voltage before ordering. Specify the power step per cabinet position, since 40kW and 50kW units are interchangeable mechanically.

Are the 40kW and 50kW units the same size?

Yes. Both use the 84mm x 300mm x 437.5mm envelope and weigh 17.2kg, so they are mechanically interchangeable.

How heavy is one module?

17.2kg, which allows one technician to lift and seat the unit without a lifting aid.

Can I upgrade a 40kW cabinet to 80kW later?

The rack and mounting are shared across the family, so a higher power step can be fitted without changing the cabinet sheet metal.

What input and output ranges are supported?

Three phase 260Vac to 530Vac input and 1000VDC to 1500VDC output across the module family.
