Smart AC Charging Infrastructure
EVSE Smart AC Chargers & Controllers
Commercial and residential Electric Vehicle Supply Equipment (EVSE) wallboxes, pedestal chargers, and embedded controller sub-assemblies built for reliable public and fleet operation.
OCPP 1.6J / 2.0.1 Ready: Native cloud connectivity over Wi-Fi, Ethernet, or 4G LTE for remote billing and fleet telemetry.
Integrated 6mA DC Leakage Detection: Satisfies IEC 62955 safety standards, eliminating the need for expensive upstream Type B RCDs.
Dynamic Load Balancing (DLB): Real-time CT monitoring prevents main circuit breaker tripping during building peak hours.
