Switching power supply

KH-SK series high-power switching power supply by our company for scientific research and industrial applications and independent research and production of a high-performance DC power supply, the internal use of IGBT module adjustment mode, output rectifier diode using the United States Fairchild, greatly reduce the heat, reduce machine loss, improve power efficiency, prolong the service life of the machine. Transformer copper wire is made of red copper material to reduce the heat loss of copper wire. The heat sink adopts customized high-density tooth heat sink to improve heat dissipation efficiency. The fan adopts imported bearing fans to reduce fan noise and prolong the service life of the fan. Other components are made of high-quality components, greatly improving the overall performance of the power supply.

Switching power supply with simple operation, small size, high efficiency, high precision, high stability and other performance, equipped with advanced LCD liquid crystal display, with perfect overvoltage, over current, over temperature, short circuit protection, so that users use the product more at ease, more stable, more reliable. It is the best choice of power supply for research units, laboratory tests and production lines.

Performance characteristics of switching power supply

· Specifications: Output voltage 0 -- rated voltage, output current O -- rated current; Power factor correction (optional);

· Voltage and current preset: the panel comes with preset buttons, which can set voltage and current values in advance;

· Stable voltage and current: the voltage and current value can be adjusted continuously from zero to the rated value, and the stable voltage and current can be automatically converted;
