The Chun Shu DC Air Conditioner is an intelligent, energy-efficient cooling system designed for telecom base stations, outdoor electrical enclosures, and hybrid power systems.
It operates on DC48V ±20% wide voltage, making it ideal for off-grid or weak-grid regions powered by batteries, solar energy, or hybrid energy sources.
With a fully inverter-controlled system, it delivers precise temperature control, high efficiency, and ultra-low energy consumption, ensuring 24/7 stable operation even under extreme conditions.
Full DC Inverter Design
Equipped with a PID intelligent control board, the system dynamically adjusts compressor and fan speed for optimal efficiency.
Wide Voltage Operation (DC48V ±20%)
Stable performance under fluctuating power input from renewable or backup systems.
Energy-Saving BLDC Compressor + EC Fan
Hitachi high-temperature rotary DC compressor combined with EC centrifugal fans ensures high efficiency and low noise.
High Sensible Heat Ratio Design (≥95%)
Delivers strong cabinet cooling with minimal condensation, protecting sensitive electronic components.
Intelligent Control & Remote Monitoring
Microcontroller-based PID regulation with RS485 (MODBUS-RTU) communication for remote supervision.
Compact Door/Wall-Mounted Structure
Simplifies installation and maintenance while maximizing internal cabinet space.
IP55 Outdoor Protection
Dustproof, waterproof, and corrosion-resistant - suitable for desert, coastal, and tropical environments.
