What is a switching power supply

Definition: A power box that converts alternating current into direct current. A switching power supply is not a switch.

Because the switching power supply has a transistor inside (now using MOS tube) switch about 65000 times per second (we taste the switching frequency of 65KHz, of course, there are higher 90K, 200K and so on), so named switching power supply.

Application industry: Industrial automation, 5G communication, lighting and display, medical, security, power control, metallurgy, water treatment, infrastructure and various other.

Zhejiang Junlin Electric Technology Co., Ltd. is a professional switching power source factory, wit20 years of experience in the production of switching power supply, its own brand, the products are exported to many overseas markets, with more than 100 employees, OEM/ODM support, with CE,CCC,ROHS,ISO9001 and other certificates.

By ensuring our designs are compliant with international standards, we provide solutions for low, medium and high power applications from trusted global brands.
