4.5kW On-board DC/DC Power Module
EVMC24-4500MF
The EVMC24-4500MF is an on-board DC/DC power module featuring DC voltage input and adjustable DC voltage output. Utilizing DSP digital control, resonant soft-switching, and Three-level Boost technologies, the module is protected by multiple patents. It is characterized by high power density, a wide input voltage range, an extensive operating temperature range, high efficiency, vibration resistance, and superior EMC performance. The module integrates comprehensive protection mechanisms—including input over/under-voltage, output over-current, output over-voltage, output short-circuit, and over-temperature protection—while also supporting multi-module parallel operation. Notably, it features an independent air duct design for high heat dissipation efficiency.
