Rx SOLUTIONS cooling fans and blowers provide cooling solutions to your system thermal problems. The need for forced-air cooling by using an AC or DC axial fan or blower should be determined at an early stage in the system design. It is important that the design plans for good airflow to heat-generating components and allows adequate space and power for the cooling fan or blower.
1.References for battery working time:
The tested battery capacity is 4400mAh.
The working time for the fourth gear is 8 hours and forty-five minutes.
The working time for the third gear is 12 hours and ten minutes.
The working time for the second gear is 23hours and 18minutes.
The working time for the first gear is 59hours and 52 minutes.
2.Manual:
1.Starting and instruction
Press ON/UP to check the battery capacity left, press the button for1.5second to start the cooling system. It normally shows the fourth gear.
2.Shutdown
Press the key OFF/DOWN 1.5 second, The digital Led will be putted out.
When it is unloaded, the battery will be automatically powered off in 5 second.
When the battery is exhausted, it will be also shutdown in 2s.
3.The power instruction for discharging
There are 10 grades of the battery capacity , using number from “0”to”9”to show. When
The number “0”flashes,it means lower power, and the battery will be shut down soon. and
The number”9”means the fully charged.
4.Charging instructions
After the charger connected with the DC connector, the digital tube showing
charging condition and the decimal point will remain flashing. when it
get to the full power, it shows number “9” ,and meantime the decimal point will not flash
again . The degree of the power depends on the signal light, when the charger light shows green, it means the power is fully charged.
5.Short circuit over loading protection:
When the output interface short circuit, the battery will automatically go into
The protected condition. It needs to charge to activate the battery.
6.The ability for loading
The maximum output voltage is 2A.
3. Functional parameter reference form are the following:
Gear | Battery showing number | Output voltage |
4 | 4 | 7.4V |
3 | 3 | 6.0V |
2 | 2 | 4.5V |
1 | 1 | 3.0V |
1. What is a DC/AC Axial Fan?
An AC/DC fan is usually powered by 3v, 5v, 12v, 24v, 36v and 48v. It blows air along the axis of the fan, or parallel to the track of the blade axis. Standard DC Axial fan sizes include 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 92mm,120mm, 150mm, and 200mm.
2. How to choose a AC/DC fan?
To choose a AC/DC fan, you should consider the points below
a. fan voltage
b. fan current
c. fan speed
d. fan airflow
e. fan noise
f. fan lifespan
3. What is a bearing?
Fan bearing includes Sleeve Bearing and Ball Bearing, life expectancy of sleeve bearing fan is 30000hours, while ball bearing is 50000hours or more.
4. How do we carry out quality control?
Usually, there are two ways to monitor reliability during the manufacturing process.
a. Early Life Test
This is used as a mean of process control aimed at identifying any latent manufacturing problems and determining the effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn in at 50°C+/-5°C for 24 hours.
b. On-going Reliability Demonstration
This is a longer-term program aimed at providing data on continuous basis to demonstrate the reliability of product. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at 50°C+/-5°C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions taken where necessary.
