CABLE CABINET E-MOBILITY AHMA LK16316VX

Charging stations are wall-mounted electrical units designed to meet the requirements and specifications of charging station standards. Temperature management is particularly critical in electric vehicle charging, so UTU charging stations always feature component-specific ventilation gaps and field-specific ventilation. The enclosure rating is IP31 due to the ventilated structure, which can be upgraded to IP34 by installing a protective cabinet (suitable protective cabinet LKS1090 no. 3426358). Charging Station Ahma LK16316VX Features

• Rated current 160A (selectable 100A / 125A / 160A)
• Outputs: 16 pieces ADM482C (Hager residual current device, C-curve 32A, 4-pole, 30mA)
• Input: Compact circuit breaker HHT160DR with busbar mounting (Hager H3+)
• Network analyzer with ModBus communication interface (Circutor CVM-C11)
• Input connectors HYT005H (Al/Cu 50-185mm˛)
• Charging outputs: Al/Cu terminal connectors 2.5-35mm˛

Temperature Management

In electric vehicle charging, the output components of the station often operate near their rated current, making temperature management critically important for the station’s lifespan.

The station incorporates temperature management requirements specific to charging load:

• Field-specific ventilation
• Air gaps in charging outputs
• Thermal emergency shutdown function

Charging output balancing factor 1 (as required by the charging station standard).

The station features DIN rail mounting for sensors, enabling readiness for dynamic temperature management. When connected to an eParking backend system, the charging station can dynamically control charging load based on the temperature of output components.

Lifecycle Management

The station includes a dedicated device space for load management devices. This device space is a general-purpose area suitable for installing any device. The space reserves capacity for the eTolppa system’s load management device (eG) for multi-level load management. When the eTolppa load management device is installed in the station, no separate connection device is required at charging points.

If the thermal emergency shutdown function repeatedly interrupts power supply during the station’s lifecycle, it is advisable to implement dynamic temperature management. In this mode, the backend system can continuously limit charging station loads based on the temperature of output components.

The station includes reserved space for a harmonic filter. The network analyzer can monitor the development of harmonic distortions, and a harmonic filter can be easily added to the station afterward. Alarms related to this can be configured on the analyzer.

The station also includes a separate space for spare outputs. The spare output space is standardly equipped with 3 pieces C10 and 2 pieces C16 (1-pole) circuit breakers (for other electrical needs). Spare outputs are not wired to busbars.
