Product Description
About us:
Factory area is about 11000 square meters.etablished in 2004, Shenzhen SETEC Power Co., Ltd. is one of the leading manufacturer in China specializing in designing, researching, developing, producing and selling electric vehicle charging station,high-frequency switching power supply(rectifier), DC/AC power inverters, DC/DC converters, solar pump inverters. We provide advanced technology and outstanding quality products. Our customers are operators of domestic telecommunications industry and power industry, broadcast industry, and related ancillary equipment manufacturers. Our company provides not only high-frequency switching power supply equipment for large telecom operators, but also power supplies for the relevant supporting manufacturers. SETEC devotes ourselves to the national industry development and introduces the advanced technology and management experience from world-renowned enterprises to build our own high-tech enterprise. 
       Input:  230VAC, 1 Phase
     Output:  24V/48VDC
Power supply modules of series SET- 24V/48V/220V/110V are compact battery charging rectifiers 
with rear side connectivity. 
The rectifiers are designed for high voltage Power Plants and Substations.
Due to the modular concept and a high scalability the user is able to equip the power supply with 
additional modules according to his actual power profile. The chargers are very user friendly and
can be swapped as well as upgraded during system operation.
The devices get their operation parameters via the system RS 485 communication bus. 
After a successful login a central monitoring unit controls and monitors the devices. In case of interruption
due to failure of monitoring unit the modules operate continuously with internal default values.
Therefore the supply of the connected loads and the charging of the batteries are guaranteed without any 
Step less temperature control fan speed & change with the output power of module, which minimize 
noise & extend fan life.The rectifier needs a 1Ph AC mains connection.
Rectifier power circuit is divided into active PFC & DC to DC converter which can make the wide
input voltage range (85V-290V) & high efficiency.High power density has reached the international
advanced level.
• Protection for Input and output over /under voltage, over temperature, and short circuit, Modular design 
• "Hot plug-in" design with back plane connection
• High power density
• RS 485 Interface for Remote Adjusting,Controlling, Measuring and Signaling.
• High Efficiency with low EMI
• CE Safety and EMC certification
• LED indication for On / Fault status.
These power supplies are designed for a wide range of applications such as:
• Power supply for all medium to high power DC loads
• Rectifiers in DC systems with battery backup
• Telecommunication.
• Industrial control systems.
• Charging and buffering of stationary batteries in electrical power plants
