EV Charging Station Auxiliary Power Solution
Solution Overview
The reliability of an Electric Vehicle (EV) charging station is critically dependent on its auxiliary power system. This system powers the main controller, human-machine interface (HMI), communication modules, and safety relays. Our solution, built around MORNSUN's specialized power modules, addresses the key challenges of this application: wide input voltage range, harsh outdoor temperature fluctuations, high electromagnetic interference, and the need for long-term reliability.
Key Application Requirements
- Wide operating temperature range for outdoor installations
- High EMC performance in electrically noisy environments
- Long-term reliability for 24/7 operation
- Compact form factor for space-constrained enclosures
