A new choice for high-reliability power supply in multiple scenarios! 1500W domestic AC brick power supply released

AC/DC brick power modules have high integration, outstanding power density, strict reliability requirements, and high technical barriers. The market has long been dominated by overseas leading manufacturers.

Insufficient localized supply continues to restrict the entire set of equipment from being independently controllable; domestic equipment manufacturers generally face problems such as long supply cycles, high procurement costs, difficulty in customized development, and prominent supply chain risks.

Yudun directly addresses the pain points of the industry and launches a new 1500WAC brick power supply product - JLBF1500-13BxxG series, which is suitable for many application scenarios such as ground equipment, data communications, vehicles and ships, industrial control, instrumentation, etc.

The product adopts full brick packaging, with a conversion efficiency of up to 93%, ultra-wide input voltage, wide operating temperature range, high isolation level, and built-in multiple protection mechanisms.

In addition to excellent hardware quality, product supporting technical services are simultaneously supported. Relying on the high localization rate of components, high reliability level and excellent comprehensive performance, we create better power supply solutions for industry customers.

01 Product advantages

Breakthrough upgrade of localization to strengthen supply chain security

The JLBF1500-13BxxG series AC brick power supply realizes localization of components, and adopts domestic supply chain from core power devices to various auxiliary components. For high-reliability scenarios such as industrial control and ships, localized materials can effectively avoid risks such as overseas supply restrictions, delivery fluctuations, and supply interruptions. The JLBF1500-13BxxG has a stable delivery cycle, which can optimize the comprehensive procurement cost of the complete machine and lay a solid foundation for the localization of equipment.

Ultra-wide input voltage, adaptable to complex working conditions and diverse scenarios

This series supports an ultra-wide input voltage range of 85~305VAC/120~430VDC, and can easily cope with the complex and changeable power supply environment of industrial sites.

The wide input feature is compatible with various power supply sources such as conventional mains power, industrial non-standard power supply, and backup DC bus. It can be connected to the system power supply without adding additional complex front-end voltage regulation and preprocessing circuits, thus simplifying the peripheral design of the whole machine, reducing the number of peripheral components, reducing the cost of hardware development of the whole machine and the risk of machine failure caused by peripheral device failure, and adapting to the power supply access needs of many types of equipment.

Ultra-low THD and ultra-high PF performance

Relying on a high-performance circuit architecture, this AC brick product simultaneously achieves excellent power factor (PF&>0.99@50-100% load) and extremely low total input current harmonic distortion (THD≤5%@50~100% load), significantly reducing energy consumption and grid harmonic pollution, helping customer end products easily meet energy efficiency and harmonic specifications.

High power density, comprehensive and excellent performance

Relying on innovative circuit design, the JLBF1500-13BxxG series uses standard brick packaging to achieve a high power density of 226.64 W/in³ while maintaining an output power of 1500W. The product has a high isolation voltage of 3000VAC, an output efficiency of 93%, ripple noise as low as 150mV (typ.), no-load power consumption ≤5W, and output voltage regulation accuracy ≤±1%. At the same time, comprehensive protection functions such as input undervoltage, output short circuit/overvoltage/overcurrent protection, and overtemperature protection are integrated to effectively avoid the risk of loss caused by system or equipment abnormalities.

Ultra-wide operating temperature range, adaptable to various harsh environments

Temperature performance has a non-negligible impact on product stability. The JLBF1500-13BxxG series supports the operating temperature range of -40°C to +100°C (shell temperature), and operates at full load at a shell temperature of 85°C. It can adapt to complex temperature environments such as low temperatures, severe cold, and high temperature sealed chassis. The power supply design has passed strict environmental and life tests (high and low temperature cycles, high temperature and high humidity, vibration, impact, aging, etc.) to ensure long-term stable operation under various harsh working conditions and broaden the environmental applicable boundaries of the entire machine.
