EPS-45S-24 Datasheet/PDFAs one kind of AC DC Converters, EPS-45S-24 is widely used in power supply from 20 to 45V AC, converting from input AC voltage to 24V DC voltage. It is a component of medical, industrial and security products in power solution, providing high efficient and stable power solutions.
Working principle of EPS-45S-24 is mainly composed of three parts, which are input EMI filter, rectifier module and power supply controller and main power. Input EMI filter mainly includes AC EMI filter, varistor and common-mode choke. The rectifier electrical module is composed of bridge rectifier, filter capacitor, differential rectifier, isolation transformer and other components. And the power supply controller and main power are the key parts that limit the quality of EPS-45S-24. The power supplied by the input AC voltage is pre-rectified by the rectifier module and then sent to the main power stage. Here, it is further rectified and filtered. At the same time, it is converted into a regulated DC output voltage by the integral feedback control circuit, making it suitable for various voltage requirements. After stabilizing, EPS-45S-24 supplies 24V DC voltage.
The main features of the EPS-45S-24 include low standby power, high and stable output voltage accuracy, high operating efficiency, wide input voltage range, high power factor correction, global safety standards, high reliable encapsulation, user-friendly design and excellent anti-interference performance. In addition, it is characterized by environmentally friendly, no-load power consumption as low as 0.3W and unique over-current protection.
EPS-45S-24 is widely used in various types of power supplies, such as medical power supplies, industrial power supplies, security access control systems, office electronics and vehicle power supplies. In the medical industry, it is used in constant temperature water baths, ventilators, medical beds, respirators, liquid crystal power supplies, ECG monitors, respirators, medical air conditioning, hemodialysis machines, patient monitors, medical analyzers, etc. In the security industry, it is used in security access control systems, fire alarm panels, UPS and other fields. In the industrial field, it is used in power supply for communication networks, automation equipment, industrial computers and surveillance cameras. In the office electronics field, it is used in telephones, fax machines, copy machines and small office electronics products.
