Feature: 1. The LED display screen is easier and more direct to read the working value, clear at a glance, convenient and fast 2. The 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 -to-noise ratio of the whole machine 3. Large heat dissipation area, can better maintain long‑term operation, wide working voltage with energy‑saving design, efficiency up to 90% 4. Printed circuit board adopt good quality double‑sided 1.6mm thickness PCB material, very stable 5. Made with full tinning process, guarantee good passing performance of large and small currents Specification: Item Type: Decoder ModuleMaterial: PCB Input Voltage: DC7-12V Package List: 1 x Decoder Module Note: 1. Do not use over‑load. 2. Do not use over‑voltage. 3. Do not use over‑current.
