Overview
The VoltiE RT175-S is a high power DC fast charger delivering up to 175 kW of output for corridor, fleet, and public charging sites. Hardware and enclosure are based on the proven RT175-S platform, now integrated into VoltiE services, support, and CSMS.
Configurable variants support single or dual DC outlets so that sites can deploy CCS only or CCS and CHAdeMO combinations. Power is dynamically shared by the charger control system according to connector usage and configuration policies.
The cabinet is designed for challenging outdoor environments with an IP65 (NEMA 3R) weather rating and IK10 impact protection with IK8 screen. High efficiency operation minimizes energy losses while maintaining stable performance at high currents.
Integration with the VoltiE CSMS uses standard OCPP communications, enabling central monitoring, remote diagnostics, and access control policies for public, fleet, and site specific use cases.
