Zaptec Pro charging system

This calculator is used to design Zaptec Pro charging systems by calculating available phases (either 1-phase or 3-phase), circuit size and preferred minimum charging current at full load in the charging system.

Enter: Power grid: Power grid, number of phases: Circuit size (A): Preferred minimum charging current (A)

Result: Number of active charging stations: Total available charging power in the charging system (kW): Used charging power in the charging system (kW): Minimum charging power per active charging station (kW):

Preferred number of Pro charging stations

This calculator is used to design the minimum circuit size based on the number of Pro charging stations and the preferred minimum charging current with a maximum number of active connections on the charging stations.

Enter: Power grid: Power grid, number of phases: Preferred minimum charging current (A): Preferred number of active charging stations:

Result: Minimum circuit size (A): Used charging power (kW): Minimum charging power per active charging station (kW):

Independent charging station

This calculator is used to calculate the maximum charging current for an independent charging station (charging station on a separate circuit).

Enter: Power grid: Power grid, number of phases: Circuit size (A):

Result: Total available power (kW): Used charging power (kW): Maximum charging current (A):
