250A Single Gun DC Fast Charger 10 Inch High Brightness Screen OCPP 1.6J 4G Ethernet WiFi CMS App Start

Four power steps are available on the same single gun platform, so an operator can match the bay to its actual traffic instead of over specifying every location.

Because the output voltage window reaches DC1000V, the same unit serves 400V architecture cars and 800V architecture vehicles without a hardware change.

The screen is the part of the charger a driver actually judges. A 10 inch high-brightness color panel keeps status, pricing and instructions readable in direct sun, which is the condition that defeats most low brightness displays on outdoor bays.

What the driver sees. Connection status, remaining time and delivered energy are shown in large type, and the payment or authorization prompt appears in the same flow so the driver is never asked to guess the next step.

Why it matters commercially. Clear screen prompts reduce the number of support calls in the first weeks of a new site and shorten the average session start time, which is what determines bay turnover on a busy parking level. For operators running several networks, the language package and pricing format can be set per market.

Five start modes are supported on the same unit, and the operator can enable or disable each one from the backend. A public bay, a fleet depot and a hotel guest car park rarely want the same authorization model.

RF card. Subscription fleets and closed depots: the driver taps the card on the reader, connects the gun and the session starts. Mobile APP. Public networks with account based billing: the driver selects the station in the APP, confirms and connects the gun.

CMS. Remote assistance: the operator starts the session from the backend console when a driver calls in. QR code. Walk up charging without a card: the driver scans the on-screen code, pays in the web page and connects the gun. VIN code. Plug and charge style fleet operation: the vehicle identity is read and authorization is automatic.

The unit runs OCPP 1.6J for CMS roaming, remote diagnostics and firmware updates, and offers 4G, Ethernet and WiFi with automatic failover between links. Cellular covers sites without fixed line access, Ethernet suits buildings with existing cabling, and WiFi covers indoor parking and temporary installations. If one link drops, the unit moves to the next configured link instead of going offline.

Because diagnostics travel over the same protocol, a fault code reaches the operator console without a site visit, and firmware updates can be staged across a whole network rather than one cabinet at a time.

The enclosure is IP55 and air cooled, rated from -40°C to +60°C. The sealed cabinet limits frost and condensation on control boards and terminals at the cold end, while temperature controlled air cooling manages module heat at the hot end so output is held inside the specified window instead of being throttled during the hottest hours.

Protection layers. Short circuit protection cuts output when a fault current path is detected; over temperature protection reduces or stops power before module and connector temperatures become damaging; over current protection caps output so cable, connector and vehicle inlet stay inside their rating.

Electrical and earth faults. Residual current is monitored and the session is interrupted on leakage detection, output is limited on over voltage, and the session is held or stopped on under voltage. Every event is reported over OCPP 1.6J so the operator sees the fault code in the CMS.

• 60kW / 120kW / 160kW / 240kW power rating
• CCS1, CCS2, CHAdeMO or GB/T DC connector
• 4G, Ethernet or WiFi communication
• OCPP 1.6J or standalone local authorization mode
• OEM front panel branding and language pack

• Public parking and retail charging bays
• Fleet depots and taxi charging points
• Hotel, mall and office parking facilities
• Highway service areas with limited bay space

Most installation delays come from site preparation rather than from the charger. Confirming six items before the cabinet ships keeps the commissioning schedule predictable: a three-phase 5-wire AC380V supply with capacity margin for the selected power rating; a level concrete base or plinth sized for the cabinet footprint and cable entry position; the cable distance from the distribution board together with the trench or tray path; an earthing arrangement that satisfies the local electrical code; surge protection coordinated with the building or yard system; and either usable 4G signal at the bay, an Ethernet drop, or WiFi coverage from the site access point.

Every unit is tested before shipment and covered by TUV, CE and FCC certification. OEM and ODM programs are available: enclosure branding, connector configuration, power module rating, language packs and CMS/OCPP integration can all be tailored to your project specification.

TUV provides independent safety and performance verification accepted by European project owners, CE is the conformity marking required for placement on the EU market, and FCC covers electromagnetic compliance for the North American market. For private label programs, front panel branding, connector type, language package and OCPP endpoint are defined at order stage, while the electrical architecture and protection set stay fixed because they carry the certification.

Does the single gun really deliver 250A continuously?

Yes. The gun is rated for 250A uniform charging output across the DC200V-1000V voltage window, within the specified operating temperature range.

Can I disable the APP or QR code start modes?

Yes. Each of the five start modes can be enabled or disabled from the backend, so the bay can be configured for card only or app only operation.

What happens if the network link drops?

The unit moves to the next configured link among 4G, Ethernet and WiFi. Local authorization modes keep the bay usable while the link is restored.

Will it charge 800V vehicles?

The output window reaches DC1000V, so 400V and 800V architecture vehicles are both supported without a hardware change.

Is the screen readable outdoors?

The 10 inch panel is specified as high-brightness specifically so status and pricing stay readable in direct sunlight on an outdoor bay.
