Description: size: 2.9CM*3.6CM 1, Main chip: NE555; 2, Input voltage: 5V-15VDC. (When 5V power supply, output current =15MA; when 12V power supply, output current=35MA); 3, Input current: ? 100MA 4, the output amplitude: 4.2V V-PP to 11.4V V-PP. (according to the different input voltage, output will be different) 5, Maximum output current: ? 15MA (5V power supply, when V-PP is greater than 50%), ? 35MA (12V power supply, when V-PP is greater than 50%) Characteristics and advantages: 1, output with LED indication(low level LED ON, high level LED OFF, at lower frequencies than the LED flashing); 2, the output frequency range level can be selected, the output frequency adjustable; Low frequency: 1Hz~50Hz MF: 50Hz~1kHz HF: 1KHz~10kHz HF: 10kHz~200kHz 3, the output duty cycle can Adjustable(Small), adjustable duty ratio will change the frequency. 4, the output frequency adjustable; Cycle T=0.7 (RA+2RB) c RA, RB for the 0-10K adjustable; C=0.001UF low frequency gear; C=0.1UF MF gear; High frequency in document C=1UF; C=100UF high frequency gear, wave frequency buyers can own calculation.
