Feature:1. The LED display screen is easier and more direct to read the working value, clear at a glance, convenient and fast2. The resistance uses high-accuracy chip resistors, and the main circuit adopts a five-ring metal film resistor with an accuracy of 1%, which ensures a good signal-to-noise ratio of the whole machine3. Large heat dissipation area, can better maintain longterm operation, wide working voltage with energysaving design, efficiency up to 90%4. Printed circuit board adopt good quality doublesided 1.6mm thickness PCB material, very stable5. Made with full tinning process, guarantee good passing performance of large and small currentsSpecification:Item Type: Decoder ModuleMaterial: PCBInput Voltage: DC7-12V.Package List:1 x Decoder ModuleNote:1. Do not use over‑load.2. Do not use over‑voltage.3. Do not use over‑current. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
