This DC air conditioner series is specifically engineered for telecom base stations, outdoor cabinets, renewable‑energy storage sites, and remote off‑grid locations. It employs a full‑DC inverter compressor and brushless DC fans, supporting a wide DC input voltage range (typically 48 V, 72 V, 110 V, or 310 V DC). The units can be powered directly from telecom rectifiers, solar panels, or battery banks – no external inverter is required, eliminating conversion losses and boosting overall system efficiency by 20%–30% over conventional AC fixed‑speed units. The series offers a cooling capacity range from 500 W to 3000 W (customisable upon request), fitting everything from small RRU cabinets to medium‑sized shelters. The soft‑start feature ensures smooth in‑rush current, minimising stress on limited‑capacity power supplies, making it ideal for solar‑dependent or weak‑grid sites.
Full‑DC variable‑speed control – Both compressor and fans use brushless DC motors. The controller continuously adjusts speed based on real‑time heat load and ambient temperature, achieving “cooling on demand”. Significant energy savings at partial load, with temperature fluctuation controlled within ±1 °C (setpoint adjustable from 20 to 28 °C).
Wide‑voltage adaptability – Built‑in high‑efficiency DC‑DC power management allows input voltage fluctuation within ±20% of nominal value, ensuring stable operation even when solar or battery voltage varies.
Intelligent defrost and low‑temperature start – Automatic frost detection and reverse‑cycle defrost; optional PTC electric heater available to keep batteries and electronics operational in cold climates.
Multiple protections – Over‑voltage, under‑voltage, over‑current, over‑temperature, high/low pressure, and compressor time‑delay protection; built‑in Class II surge arrestor for lightning‑prone areas.
Remote monitoring & management – Standard RS‑485 interface with Modbus RTU protocol; optional SNMP adapter for network management integration. Real‑time data includes operation mode, setpoint, actual temperature, fan speed, and alarm codes.
Corrosion‑resistant construction – Galvanised steel casing with outdoor powder coating; condenser coil epoxy‑coated; overall ingress protection rating IP54 – suitable for coastal, humid, or dusty environments.
Easy maintenance – Front panel removable; washable nylon filter (MERV‑8) can be pulled out from the front; compressor and electrical box are front‑accessible for quick servicing.
