Guangzhou Kaihui Electronics Co., Ltd. is one of the leading manufacturers and suppliers of 12 vdc 800watt power supply in China. With abundant experience, our factory offer high quality products made in China with competitive price. Welcome to contact us for customized service.
The 12 VDC 800-Watt Power Supply is a high-capacity, enclosed switching power solution engineered to deliver up to 66.6A of clean, continuous direct current. To manage this substantial output safely, the unit integrates an active Power Factor Correction (PFC) network, which optimizes electrical efficiency and significantly reduces harmonic distortion on the local grid. Housed in a robust, ventilated metal chassis with built-in intelligent forced air cooling, this module functions as the reliable backbone for energy-intensive electronic clusters where voltage drop or current fluctuations cannot be tolerated.

● All parameters are measured under the conditions of 230VAC input, rated load, ambient temperature 25℃ and humidity 70%; ● Accuracy:including setting error, line regulation,load regulation, etc. Line regulation: measured with the input voltage changes from low to high under rated load conditions; Load regulation: measured with output changes from 0 load to 100% load; Ripple test: Connect the power supply and the load with a 30cm-long twisted wire. The load end is connected with 0.1u and 47u capacitors, and it is measured at the load end with a 20MHz oscilloscope; |

FAQ
Q1: What is the typical production timeline for large bulk orders?
A: Once the project deposit is confirmed, the mass production and scheduling cycle for standard enclosed units generally takes 20 to 25 working days.
Q2: Can we modify the physical dimensions or add custom logos to the unit?
A: Yes. Full OEM and ODM services are available. This includes custom branding on the aluminum case, tailored wire configurations, and private label packaging designed to fit your corporate aesthetics.
Q3: Is it possible to request evaluation units before a major roll-out?
A: Sample orders are encouraged for rigorous validation. Typically, 1 to 5 prototype pieces can be provided, with custom sample preparation taking 7 to 10 working days after details are finalized.
