DP903 is an intelligent high-voltage power supply and multi-function mobile charging all-in-one equipment, designed for offline
driving and maintenance testing of high-voltage components, as well as mobile charging scenarios for repair vehicles.
Features
- Integrates fast charging for the whole vehicle, blind charging for battery packs, and high/low voltage power supply for automotive components.
- High-voltage and low-voltage modules operate independently, ensuring stable performance and enhanced safety.
- Multiple built-in protection mechanisms for safe and reliable operation.
- Foldable casters design enables easy mobility and convenient desktop placement.
- Equipped with a 10-inch high-definition touchscreen for intuitive and smooth operation.
Functions
- Low-voltage output: Provides 12V / 5A maximum constant DC output.
- High-voltage output: Supports 50–1000V DC output with adjustable voltage and current via touchscreen.
- Vehicle charging: Supports charging the entire vehicle through a national standard fast charging gun, suitable for maintenance, inspection, and emergency scenarios.
- Blind charging of battery packs: Enables safe and efficient battery pack charging without relying on the BMS.
- BMS data acquisition: Reads SOC, voltage, current, temperature, and cell status for battery protection and health assessment.
- Comprehensive protection: Includes overvoltage, undervoltage, overtemperature, short-circuit, reverse connection protection, and current limiting.
