The electromagnetic frequency of the generator is 150MHz, and high-efficiency light bulbs can be lit without power supply. 3 holes are separately, and each hole takes about 30 minutes to charge. When the indicator of the charger is turned off, it means it is fully . Easy to operate: When the instrument is close to the light-emitting tube part of the lamp, the light will turn on, indicating that the instrument is good and relevant tests can be carried out. ABS housing: The ABS shell of the pulse generator has excellent flame retardant and insulation, so you don't have to worry about . Wide range of uses: High-frequency strong magnetic generators can be used in electronic factories, laboratories, electronic research and development and other factories to test the anti-interference test of electronic motherboard experiments. Frequency: 150MHZ Typical applications: Fingerprint lock, slot machines, claw , game machines, etc. Working voltage: DC 36V Antenna mode: built-in reinforced antenna + external high-frequency antenna Power supply voltage: DC 36V Charging time: 1.5 hours in total Charger: input110-220 VAC Built-in rechargeable battery Note: Intermittent work (one click).
