Smart LED Tester for Quick SMD and Backlight Diagnostics
The DLV-300 smart LED tester is an essential tool for anyone repairing or checking LED circuits — from LED strips and SMD panels to TV and monitor backlighting. Automatic adjustment of output voltage and current protects the tested components and eliminates the risk of accidental burnout. The integrated digital display shows the output voltage in real-time, making checking a single LED or an entire row of diodes a quick and precise operation.
What you get with this product
- Quickly identify faulty LEDs without disassembling the entire circuit — save time and avoid unnecessary replacements
- Voltage and current adjust automatically according to the component being tested — don't risk burning out healthy LEDs during checking
- Compatible with a wide range of components: SMD LEDs, Zener diodes, LED panels, LED strips, TV and monitor backlighting, LED projectors
- Integrated digital display showing real-time output voltage — you know exactly what parameters you're working with for each test
- Direct power from 220V outlet via included EU cable, no batteries needed — always ready for bench work
- Compact dimensions and probes included in the package — fits into any service kit, ready for immediate use
How it works and how to install it
The tester connects to a standard 220V outlet via the included EU cable. The probes (red and black) are applied directly to the terminals of the LED or component to be tested — the device automatically detects the necessary parameters and adjusts the output voltage between 0 and 300V DC to illuminate the LED without overstressing it. No manual configuration is required: connect, apply the probes, and read the result on the digital display.
Frequently Asked Questions
Can I test a TV's LED backlight with this device without removing the board from the TV?
Yes, the probes allow direct access to the LEDs on the backlight bar even with the board partially mounted, as long as you have physical access to the terminals.
Is it dangerous to use if I am not a professional electronics technician?
The device is designed for workbench use with components disconnected from mains voltage; please follow the included safety instructions and do not short-circuit the probes.
Can it test Zener diodes or only LEDs?
Yes, the DLV-300 tester is compatible with SMD LEDs, conventional diodes, Zener diodes, and LED panels, not just LED bulbs or strips.
