Detailed Product Description

 

1. Description

 

The DC Variable Frequency Air Conditioner, with low energy consumption, is suitable for outdoor environment with large temperature difference. It uses DC-48V(-45V~-60V) input, PWM centrifugal fan speed adjustment, and object unit temperature PID adjustment mode. The input power can be adjusted according to cooling capacity demand. The Max. cooling capacity is 650W, but input power is only 216W.

 

The DC48V Variable Frequency Air Conditioner is a full automation temperature control product. It uses intelligent controller to control the whole system of the air conditioner. According to the variation of environment temperature, the intelligent controller can automatically detect, operate and record the whole system’s operating time, power consumption, event and historical data. It can store 100 event records and 1280 historical data records, and can enquire 256 days’ daily record information. The product is widely applied in telecom cabinet, small and medium sized telecom room, UPS room, outdoor base station room, etc.  The air conditioner includes the following specs: 300W, 500W, 1000W, 1200W, 1500W, 2000W. In addition, it also can be custom made.

 

2. Features

 

   (1) Thermostatic internal temperature: 26°C;
   (2) When environment temperature is 35°C, the input power is only 216W;
   (3) Control system fault detection, perfect smoke and water alarm input linkage;
   (4) Air exhaust temperature detection, compressor state real time detection ;
   (5) Lightning proof, for outdoor use;
   (6) Temperature dynamic adjustment, very low power consumption, specially designed for integrated cabinet;
   (7) Protection level: IP55.
