Hefei Rijin Electronics -  supplier of Gree air conditioner controller

It has the production capacity of 5000 sets of air conditioner controllers per day. For many years, Rijin Electronics has been supplying various controllers for Zhuhai Gree, Nanjing Huamai, Zhejiang Shuaikang, Hangzhou Gaoteng, Anhui Meteorological Bureau, Zhongshan Power, Jinan Xiaoya, Hefei Rongshida and other enterprises.

In 2013, when it came to new procurement options, Rijin Electronics introduced a new ASEMI brand, a rectifier bridge D50SB100 with its own patents and its own heat dissipation effects.

In the process of the sample, D50SB100 not only has stable performance, but also has a slow temperature rise and small heat dissipation. The excellent performance has been favored by the chief engineer of Rijin electronic circuit design.

We know the working characteristics of air conditioning controller equipment, usually high switching current overcurrent and greater working power than ordinary appliances. Because the air conditioner controller needs to be started quickly in a short time, when the voltage is constant, it is necessary to apply a large current in a short time to achieve a high power effect.

Why is the ASEMI rectifier bridge D50SB100 ideal for air conditioning controllers? Below we answer this question with a simple data calculation -

Commercial air conditioner controllers generally have powers ranging from 2000W to 5000W. We calculate them with a maximum power of 5000W. Assuming the input voltage is 220V mains, the operating current of the induction cooker is:

5000/220=22.73 amps

The safety margin is reserved according to the operating current of 3-5 times. The rectifier bridge is selected by this safety principle. Actually, two D50SB100 can complete the rectification work in the controller scheme design.

If the design scheme is 2000W power, then the above formula is used to calculate. Therefore, engineers of ASEMI and Rijin Electronics believe that the D50SB100 is very suitable for air conditioner controllers, high-power equipment such as water heaters.
