M 系列灯珠维修测试仪M-series bead testers

面向维修师傅的隔离型 LED 灯珠 / 电视背光维修仪：免拆屏点亮、变压器隔离更安全、硬件缓输出保护灯珠。系列含 MCA220、MCT220 与旗舰 MCL300。

Isolated LED bead and TV backlight testers for repair benches: light panels without removing the LCD, transformer isolation for safer handling, and soft-start output that protects beads. The line covers MCA220, MCT220 and the flagship MCL300.

系列共同特点

Shared highlights

免拆屏：表笔接灯条口即可点亮，不必拆开液晶屏
变压器隔离：输出与市电隔离，单触一极更安全（仍严禁同时触碰正负极）
缓输出保护：硬件缓升电压，降低烧灯珠风险
自动适应：自动调节输出电压，适配不同灯串
维修台友好：体积小、插电即用，配套万用表笔

No panel teardown: probe the strip connector and light the beads without removing the LCD
Transformer isolation: safer single-pole contact (never touch both poles)
Soft output ramps voltage in hardware to protect beads
Auto matching of output voltage to the string under test
Bench-ready: compact, plug-in use with multimeter-style probes
