Electrical Performance Parameters

Output Power Three-phase 40KW / single-phase6.6KW	Input Voltage Range Three-phase 267~456VAC single-phase 154~265VAC	Maximum Input Current Three-phase 63A / single-phase 32A
Operating Frequency 45~65Hz	Power Factor 0.99 （Rated input, rated output, over half load)	Output Voltage Range 200 ~ 700V dc
Output Voltage Accuracy ±1%	Output Current Accuracy ±1%	Maximum Output Current 85A (three-phase) / 14A ( single-phase)
Efficiency >95% (peak efficiency)	Low Voltage Input Power 24V（4A Max), about 100W （The vehicle is required to provide 24V low voltage)	Output Response Time <5s When powering on, the time for the output voltage to reach a stable value is less than 5s after receiving the startup command; when shutting down, the current drops from 100% to 0A within 300ms after receiving the shutdown command.
Overtemperature Protection When the coolant temperature exceeds 65℃, the output current decreases linearly, and exceeds 85℃, the shutdown protection is applied.	Protective Properties Input over/under voltage, output over voltage, over temperature protection, over current protection, communication failure protection, internal failure protection
