CABLE CABINET E-MOBILITY AHMA LK12406X

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 LKS890, part no. 3426356). Charging Station Ahma LK12406X Features

• Rated current 125A (selectable 80A / 100A / 125A)
• Outputs: 6 x MCN340E (Hager circuit breaker C-curve 40A, 3-pole)
• Supply: Compact breaker HHS125DC with busbar mounting (Hager H3+)
• Network analyzer with ModBus communication (Circutor CVM-C11)
• Supply connectors HYS005H (Al/Cu 35-120mm˛)
• 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 service life.

The station incorporates temperature management features tailored to charging load demands:

• Field-specific ventilation
• Air gaps at 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.

Service Life Management

The station includes reserved space for load management devices. Load management space is a general device compartment suitable for installing any device. Reserved space is allocated for the eTolppa system load management device (eG) to support multi-level load management. When the eTolppa load management device is installed in the station, no separate connection device is required at charging stations.

If the thermal emergency shutdown function repeatedly interrupts power supply during the station's service life, 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 later. Alarms related to harmonics can be configured on the analyzer.

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