PlugStream DC platform principles
Liquid-cooled from 60 kW
A monitored closed loop keeps ambient air away from the critical converter electronics.
Eight-bay modular chassis
Six power positions sit alongside dedicated control and independent safety bays.
Optional N+1 resilience
Populate the sixth power bay so rated output can continue with one converter isolated.
Connected service architecture
AmpNexus control, Sentinel monitoring and Passport identity are designed into the platform.

Adds one further liquid-cooled converter module, its protected power branch and coolant connection. The remaining modules can retain the charger’s rated output if one power module is safely isolated.
Match the grid connection
Install the platform once. Configure the site around it.
A DC180 can, for example, operate at a 150 kW site limit while retaining its standard three-module hardware. That gives the operator a defined route to use the full model rating when the grid connection or energy strategy changes.
Guide prices establish the charger-hardware baseline. Installation, civils, incoming electrical infrastructure, payment equipment and project-specific service packages are added to the site proposal.
Designed applications
For depot, public and commercial high-power charging.
The common DC60–DC300 platform lets project teams match the first installation to the available grid connection, vehicle duty and resilience requirement while retaining a defined expansion path.
Fleet and depot charging
Repeatable high-power bays, site-capacity control and module-level service visibility for fleet and depot operations.
Public fast-charging sites
Roadside, destination and charging-hub deployments with Luviq operation, payment-terminal and roaming scope added to the project.
Logistics and industrial sites
Sealed power electronics, monitored liquid cooling and focused module replacement for demanding operating environments.
Commercial energy projects
Coordinate charger output with the available supply, site load-management strategy and future 60 kW expansion steps.
Thermal architecture
Closed-loop liquid cooling across every power level.
DC60 through DC300 use the same monitored liquid-cooling approach. Heat moves to an external heat exchanger while the sealed converter electronics remain isolated from the dust, moisture, salt and roadside contamination around the charger.
Sealed critical electronics
Ambient air cools the external heat exchanger instead of being drawn through the power converters, reducing exposure to dust, moisture, salt and roadside contamination.
Less filter-led maintenance
Removing high-volume ambient airflow through the converter electronics reduces reliance on power-module filters and the routine visits needed to inspect or replace them.
Condition-led servicing
Flow, pressure, temperature, coolant level, pump state and leak detection give Sentinel evidence to identify deterioration and plan work around condition rather than a calendar alone.
One thermal platform
Liquid cooling starts with DC60 and scales to DC300, creating a consistent engineering and service approach for roadside, depot, coastal and demanding industrial environments.

Understanding the charging envelope
Each converter can deliver up to 200 A across its 200–1,000 V DC operating range. A DC60 reaches its full 60 kW commercial output at approximately 300 V and above; at lower vehicle voltages, available power follows the voltage-and-current envelope. Higher power models are also governed by the selected CCS2 cable current and the vehicle’s requested voltage.

8Safety and auxiliary bay
One eight-bay chassis
Six power bays. One control bay. One independent safety bay.
Every DC60–DC300 configuration uses the same vertical chassis architecture. Power modules slide into guided positions while the application-control and safety functions remain separate, replaceable assemblies.
60 kW commercial building blocks
Each 62.5 kW liquid-cooled converter is operated as a 60 kW commercial block. One to five modules create the DC60, DC120, DC180, DC240 and DC300.
Slide-in power-module replacement
Guided rails bring each module to its rear AC, DC, coolant and control interface. There is no redundant enclosure around an already serviceable power module.
Independent control and safety bays
The seventh bay runs charge-point applications and connectivity. The eighth bay independently supervises safety, auxiliaries and the decision to energise the vehicle.
Upgrade within the installed chassis
The chassis and cooling manifold support six module positions. Add 60 kW blocks as demand grows, while site protection and output hardware are upgraded for the new rating.
Serviceability
Isolate the fault. Replace the module. Return to service.
Power conversion, application control, deterministic safety and thermal management are separate subsystems. Service work can target the affected assembly instead of replacing or rebuilding the complete charger.
Power-module replacement
Isolate the affected branch, release the module, disconnect its dry-break coolant interfaces and slide in a replacement without rebuilding the cabinet.
Replaceable control cassette
The application controller, charge communication, OCPP client and connectivity live in a separate cassette that can be swapped independently of the high-power assemblies.
Persistent charger identity
The chassis retains its serial, hardware record, configuration, commissioning history and PlugStream Passport identity when a service cassette is replaced.
Connected operations
Control, monitoring and service evidence in one operating model.
AmpNexus runs the connected charge point and its OCPP sessions. PlugStream Sentinel records power, cooling, safety and service signals so operators and support teams can see the condition of each charger.
AmpNexus control
Charger control, OCPP sessions, site-capacity limits, module inventory, software lifecycle and reporting sit within the wider AmpNexus charging estate from commissioning onward.
Sentinel monitoring
Sentinel combines live condition signals with configuration, history and service evidence for remote diagnosis, planned intervention and fleet-level reporting.
Monitored evidence
- Module availability, current sharing, temperature, runtime and derating
- Coolant flow, loop pressure, supply and return temperatures
- Pump duty, radiator performance, coolant level and leak detection
- DC contactor state, insulation-monitoring status and safety events
- Service history, module identity, firmware and configuration evidence
