FC-2G lightning protection device tester (varistor tester) In the measurement of varistors, the DC/DC converter is driven by a high-frequency pulse to raise the 12V DC voltage to the test varistor. Required DC high voltage. When testing the discharge tube, the slope control circuit controls the DC/DC converter so that its output voltage rises to discharge tube discharge at a rate of 100V per second in 5 to 1700v.

Old-fashioned Bluetooth Speaker
For Old-fashioned Bluetooth Speaker, I personally think that when many people buy Vintage speakers, the appearance is the first priority and the function is second.
We focus on retro Bluetooth speakers,It has high energy density, mini size, light weight and diversified shapes;Excellent fast charging performance, support fast charging and other excellent features with a brand-new design, showing retro nostalgia without losing fashion. It uses a 2.5-inch speaker and has many functions such as FM radio, Bluetooth fast connection, multi-mode switching, and HIFI high fidelity. Wireless Bluetooth 4-10 hours of playback (at 50% volume), which adds to its unique charm.
The sound quality of small speakers is also good. It does not have the same large speakers and power as HIFI speakers, and its sound quality cannot compete with large speakers due to physical limitations. But for the vast majority of users who are not golden ears, the use of small speakers with tablets and mobile phones is sufficient to meet their hearing requirment.
