　　【功能詳情 Function Introduction 】

　　1、可引線到燈具外部調電流該產品為方便電源內置燈具實現快速調節電流，輸出端設計外接引線端口，可將電流撥碼外引至燈具上，實測支持外出引線0.5米長(線徑0.5平方毫米)外出調電流，不影響整燈電氣和EMC性能。

　　1. The DIP switch can be used outside the driver

　　To achieve convenient brightness adjustment for the light used with built-in LED driver, we design a terminal for the external wire at the output end. With the wire, the DIP switch for adjusting current can be attached on the light instead of inside the LED driver. It supports external wire of 0.5 meter long (diameter of 0.5mm2 ) and will not affect electrical and EMC characteristics of the finished light.

　　2、四版本端口對比紅色電流撥碼與側邊色溫撥碼組合變化

　　2.Terminals of Four Versions

　　Combination of red DIP switch (adjust current) and DIP switch on the side (adjust CCT)

　　泰山系列非隔離UFO電源不僅是萊福德元老級非隔離產品，也是市場上首款非隔離大功率UFO產品。在這個全新的賽道上，如何選擇前進的方向?萊福德的答案是以客戶為中心，挖掘客戶潛在需求，解決客戶應用問題，持續進行產品優化升級。

　　LF-FHBxxxYxIV——泰山四代就是泰山系列不斷優化的最新一代。本次迭代主要優化了非隔離電源應用的核心痛點——調光關閉后仍有部分微光殘留。

　　萊福德利用獨家設計的新型電路，實現非隔離UFO的調光關斷無余輝效果，徹底解決非隔離電源應用的市場痛點，并獲得榮獲國家專利技術。

　　UFO non-isolated high bay driver is one of Lifud’s classic non-isolated products, which is also the first non-isolated high power UFO driver in the market. Facing challenge from more and more similar products, Lifud insists on customer-centered, digs out the potential needs of customers, solves application problems and continuously optimize and upgrade products.

　　LF-FHBxxxYxIV series is the latest generation of our non-isolated high bay driver. This upgrade is designed to solve the general problem of non-isolated driver in application---the light does not go out completely after dimming off.

　　To solve this problem, we applied our innovative circuit design in LF-FHBxxxYxIV series. With this driver, the light can be dimmed to off and goes out completely (as shown in the

　　left picture below). And we’re very proud that this circuit design was awarded national patent.

　　除此之外，泰山四代還優化了產品外觀、功率范圍、雷擊殘壓，并新增過溫保護、多調光選擇、正負調光邏輯可選等多項功能。

　　Besides, the LF-FHBxxxYxIV series also upgrades its appearance, output power range, residual voltage and etc. Multiple functions are available, including over temperature protection, dimming options, negative and positive dimming logic and etc.
