Voltruc Switching Power Supply use in Substation
Industry Background
Power plants and substations extensively use DC operating power supplies, relay protection devices, and closing mechanisms, which require highly reliable DC panel power supplies, typically 110Vdc or 220Vdc systems. Power equipment must withstand high-voltage DC surges and provide redundancy capabilities.
Core Requirements
- High-voltage DC input/output (110V/220V)
- High reliability with N+1 redundancy design
- Strong anti-interference capability to adapt to harsh electromagnetic environments
- Real-time monitoring and fault alarms
- Recommended Product Portfolio
