Description

Amazon Product Parameters: Input voltage: 5V~15VDC. Output current reaches approximately 15mA with a 5V power supply; approximately 35mA with a 12V power supply. Input current: >=100mA, Output amplitude: 4.2V V-PP to 11.4V V-PP (output amplitude varies depending on input voltage), Output current: ≥15mA (5V power supply, V-PP greater than 50%), ≥35mA (12V power supply, V-PP greater than 50%). Applicability: This product is suitable for electronic projects and repairs, and is suitable for a variety of devices. The output has an LED indicator. The LED turns off at low frequencies and flashes at low frequencies, providing clarity and convenience. The output frequency range is selectable (with short-circuit protection) for a more continuous output frequency. Output frequency: Low frequency: 1Hz~50Hz, medium frequency: 50Hz~1kHz, medium-high frequency: 1kHz~10kHz, high frequency: 10kHz~200kHz. Period T = 0.7(RA + 2RB) C RA and RB are 0-10kΩ; for low-frequency range, C = 0.001µF; for medium-frequency range, C = 0.1µF; for medium-high-frequency range, C = 1µF; and for high-frequency range, C = 100µF. Therefore, you can calculate the frequencies in the table yourself.
