High frequency DC Switching power supplies

Intelligent Electronic Electroplating Power Supply

1. Rectifier manufacturing standards
national standards: GB/T 385901-93 "the basic requirements of the semiconductor converter sets"
industry standard: JB/T 1504-93 "power semiconductor devices and rectifying equipment"
enterprise standard Q/SCD 002-2008 "high frequency dc switching power supply"
2. Technical parameters
2.1 Input power supply
nput voltage: three-phase three-wire system, AC220V + / - 10%;
 input power: 65 va - 8 kva;
input power frequency: 47 hz - 60 hz.
2.2 DC output part of rectifier
rated output voltage: 0-36 v is optional;
  rated output current: 0-200 - a optional;
  rated output power: 60 w - 7.2 KW.
2.3 Rectifier form

  the original edge using high frequency power supply of the highest efficiency of the whole bridge inverter technology in;
  pay side use schottky full-wave rectifier;
3. Electrical performance
3.1 Under the rated condition, the output current is level I, which can work continuously at full load;
3.2 The working state can be selected in the stable voltage and current limiting or stable current limiting, and the accuracy of voltage and current stabilizing is ±1%;
4. Cooling mode of rectifier power supply
Adopts the self-cooling method of enlarging the radiator, the internal structure of the whole machine is sealed, which can effectively isolate from the outside environment, and the internal anti-corrosion performance is several times higher than that of ordinary air cooling.
5. Protection function of rectifier power supply
5.1 Loss of phase protection: when the power intake line is out of phase, the rectifier will automatically block;
5.2 Over-current protection: when the current exceeds the rated value, the rectifier will automatically be in the current limiting state until the fault is eliminated;
5.3 Short circuit protection: when the DC side is short circuit, the electronic switch will automatically act to block the given output. When the AC side short circuit NM air switch will automatically trip, cut off the AC input;
5.4 Over-temperature protection: when the base temperature rise of IGBT Schottky and other power devices is ≥40K, the power supply will be automatically blocked;
5.5 Under voltage protection: when the input voltage is lower than AC350V, the power supply will automatically stop working or fail to start.
6. Control of rectifier power supply
6.1 The power supply adopts digital control or analog control, which can be switched between manual and automatic operation. The numerical control mode is equipped with RS485 interface, which can facilitate system networking and communication with PLC and other upper computers.
6.2 Digital panel operating platform independently developed by the company is adopted to ensure system stability, high reliability and easy maintenance. Can start/stop, voltage/current stabilization and output set operations.
7. Equipment characteristics
7.1 The coating has strong brightness range, leveling property, toughness and uniform plating ability.
7.2 For non-ferrous metals and alloys and other small workpiece plating, strong penetration, good adhesion.
7.3 Small volume, light weight, high efficiency, high control precision.

7.4 Adjustable output voltage and current.
7.5 Complete protection function, with output overcurrent, overheating, short circuit and other protection functions.
7.6 The measures to prevent salt mist acidification are adopted in the structure to increase the service life of the power supply in the harsh environment.
7.7 The self-cooling structure is adopted, and the internal components are completely isolated from the outside world, so that the installation of the equipment can be completely free from considering the corrosive acid fog in the working environment, or even directly installed in the place where the acid fog is the most serious. The self-cooling cooling method has stronger anti-corrosion effect than air cooling equipment, but avoids the trouble of installing water pipes and erecting lines for water cooling equipment. It is the best choice of power supply for plating small workpieces such as non-ferrous metal and alloy.
8. Operating environment
8.1 Working ambient temperature: T≤45℃;
8.2 Air humidity: relative humidity < 85%;
8.3 Altitude: h≤1000m, if higher than 1000m, the rectifier shall be used with reduced capacity;
