The relationship between output power and input voltage is shown in Figure 1-1 (T≤55°C). When the input voltage is between 250Vdc and 850Vdc, the module can output maximum power.
Figure 1-1 DC Input Power Limiting Curve
When the charging module has rated input voltage, the allowed output power is 20kW. The relationship between output voltage and output current is shown in Figure 1-2
Figure 1-2 Output voltage vs. Output current curve
Temperature derating
Below 55℃ ambient temperature, input voltage above 250Vdc, the module outputs 20kW at full power, and the maximum output current is 50A;
At 55℃ ambient temperature, the module allows output power less than or equal to 20kW;
At 75℃ ambient temperature, the module allows output power less than or equal to 10kW,
Above 75℃ ambient temperature, the module output power drops to 0.
