HBL1025数据手册电路保护的照明保护规格书PDF

描述 Description

The HBL1015/25 Series are electronic shunts which provide a
current bypass in the case of LEDs going into open circuit. LEDs are by
nature quite fragile when subjected to transients and surge conditions.
There are also many cases where high reliability of the LED lighting
must be maintained such as in headlights, lighthouses, bridges, aircraft,
runways and so forth. In these cases the low cost addition of the HBL
device will provide full assurance that an entire string of LEDs will not
extinguish should one LED fail open. The HBL device is also
applicable to other loads where circuit continuity is required. The
devices can be used with currents from 140 to 500 mA.

特性 Features

• A Bidirectional Device
• Automatically Resets Itself if the LED Heals Itself or is Replaced
• ON−State Voltage Typically 1.8 V
• OFF−State Current less than 0.5 µA
• These are Pb−Free Devices

应用 Application

• LEDs where Preventive Maintenance is Impractical
• LED Headlights
• LEDs with High Reliability Requirements
• Crowbar Protection for Open Circuit Conditions
• Overvoltage Protection for Sensitive Circuits

简介

HBL1025属于电路保护的照明保护。由制造生产的HBL1025照明保护采用 LED 分流或浪涌保护技术的照明保护器件专门设计用来在过流、过压或反接的情况下保护 LED 和其他照明电路。这些器件可根据工作电压范围、钳位电压和安装类型（包括底座安装、自由悬挂、支座、螺丝或表面贴装）进行选择。
