Features
- Adjustable Output Voltage Range (43.2 – 57.6VDC): Offers fine control for varying system requirements and battery types, with a default of 53.5VDC.
- Low Ripple Output (<150mVPP): Delivers clean DC power with minimal interference, ensuring safe operation of sensitive telecom equipment.
- Intelligent Current Sharing: ±5% current sharing accuracy enables efficient load balancing in multi-rectifier systems.
- Inrush Current Limiting: Prevents electrical stress on components during hot-plug installation or power-up, protecting the system and extending lifespan.
- Altitude-Tolerant Design (up to 4000m): Built to operate reliably in high-altitude installations, including remote and mountainous telecom sites.
- Visual Status Indicators: Onboard tri-colour LED alerts for normal operation, warnings, and alarms—enabling quick diagnostics and local visual monitoring.
