This DC air conditioner series is purpose‑built for telecommunication base stations, outdoor cabinets, and renewable‑energy sites. It features a full‑DC inverter compressor and accepts a wide DC input voltage range (typically 48 V, 72 V, 110 V, or 310 V DC), allowing direct connection to telecom power or PV/battery systems without an external inverter. This eliminates conversion losses, improving overall system energy efficiency by over 20% compared to conventional AC units. The soft‑start function ensures smooth in‑rush current, minimising stress on limited‑capacity power supplies. The intelligent controller automatically adjusts compressor speed based on real‑time heat load, maintaining precise internal temperatures (setpoint 20–28 °C) while reducing noise and energy consumption under partial load. Available in multiple cooling capacities (e.g., 500 W, 1500 W, 3000 W) to suit various cabinet and shelter sizes. The robust metal casing offers IP54 protection, with corrosion‑coated condenser coils for harsh, dusty, or humid environments. Standard RS‑485 Modbus communication enables remote monitoring and alarm reporting via site management systems. Optional electric heating ensures battery performance in low temperatures. Compact and flexible for wall or floor mounting, easy to maintain – a reliable green‑cooling solution for telecom and new‑energy applications.
