1. Electrical Architecture & Operational Boundaries
Passive Interface Design
Utilizes a passive electrical connection design for direct physical conversion and control signal continuity:
- Direct physical connector interface adaptation
- Continuous AC power path & control signal pass-through
- No AC/DC conversion or voltage transformation
- No internal power boost or independent charging control
80 A High-Current AC Capability
Rated for up to 80 A AC maximum current across a 120–240 V AC operating voltage range, enabling up to 19.2 kW maximum power transfer when supported by the vehicle onboard charger and electrical circuit.
*Actual charging power depends on vehicle onboard charger capacity, EVSE output, and local wiring limits.
AC Charging Only Specification
Engineered strictly for AC charging equipment. Must not be used with high-voltage DC fast charging systems.
2. Hardware Safety & Mechanical Durability
Integrated Locking Mechanism
Features an integrated mechanical lock designed to establish a firm physical latch between the J1772 connector and the NACS vehicle inlet. This structural locking mechanism improves contact stability and prevents accidental disconnection during active charging sessions.
IP55 Weather-Resistant Enclosure
Constructed with an IP55-rated sealed enclosure suitable for indoor and outdoor AC charging installations. The sealed housing guards internal contacts against environmental dust accumulation and direct water spray during daily use.
Durable Mechanical Construction
Engineered with reinforced housing materials and high-conductivity contact pins rated for over 10,000 no-load mating cycles, ensuring long-term mechanical reliability for intensive daily commercial and personal operation.
3. Interoperability & Application Scope
J1772 EVSE to NACS Vehicle Compatibility
Bridges legacy SAE J1772 AC charging cables with NACS-equipped electric vehicles. Ideal for drivers requiring access to home J1772 wallboxes, workplace chargers, or public destination chargers.
System Compatibility Factors
While physical conversion is direct, final charging availability remains subject to vehicle onboard charger acceptance, EVSE firmware configuration, and vehicle manufacturer policies.
