DEF 40
Compact DC Charging Built for Commercial and Fleet Scenarios
Available in 20 / 30 / 40 kW, this single-port CCS2 charger supports a 100V–1000V wide voltage output range, ensuring compatibility across mainstream and next-generation EV models. With high-efficiency power conversion and intelligent load control, it minimizes dwell time and maximizes session turnover, directly improving revenue per charging bay.


Deploy Without Grid Upgrades
The 20–40 kW power range operates within the capacity of most existing commercial electrical installations, eliminating costly grid reinforcement works. Compared to 60 kW+ equipment, hardware, installation, and energy costs are all materially lower, reducing total project investment and shortening the payback period for both single-site and multi-site operators.
7-Layer Protection, All-Weather Rated
Seven active protection mechanisms: overcurrent, short-circuit, ground fault, surge, over/under-voltage, over/under-frequency, and over/under-temperature, prevent faults before they cause downtime. IP54 and IK08 ratings enable direct outdoor installation without additional enclosures. A -30°C to +50°C operating range covers all European climate zones, minimising unplanned outages across the full deployment lifecycle.


Built for Remote Network Management
Native OCPP 1.6J with dual 4G and Ethernet connectivity integrates seamlessly with leading platforms including Monta and ev.energy, as well as private back-office systems. Remote monitoring, session data collection, fault alerts, start/stop control, and OTA firmware upgrades are all supported, reducing on-site service visits and lowering operational costs across distributed networks.
MID-Certified Metering
The integrated MID-certified energy meter delivers traceable, auditable consumption data that meets statutory metering requirements for public charging infrastructure throughout EU member states. Operators hold full legal billing entitlement from day one, with measurement records that eliminate billing dispute risk and satisfy regulatory scrutiny without additional certification.


Wall-Mount Installation
At 660×480×156 mm and 42 kg, the unit mounts directly to any load-bearing wall, no ground embedment, concrete foundation, or parking bay footprint required. Sub-10W standby consumption supports permanent energised standby at negligible cost. Short installation timeline and minimal site disruption make it the practical choice for retrofit projects across hotels, office buildings, retail complexes, and industrial parks.
