Size:35x33mm
The main chip:NE555
Input voltage:5V-15V(note:DC 5V power supply,the output current can about 15MA; 12V power supply, the output current can be about 35MA)
Input current:≥100MA
Output amplitude:4.2V V-PP to 11.4V V-PP(depends on the input voltage,the output amplitude is not the same)
Maximum output current:
≥15MA(5V power supply,V-PP greater than 50%)
≥35MA(12V power supply,V-PP greater than 50%)
Product Features:
1. Output with LED indication, whether there is an output or not can be directly understood (LED on at low power level, LED off at high power level, LED flashing at relatively low frequency)
2. Optional output frequency range and grade, making the output frequency more continuous and adjustable
Low frequency range: 1Hz~50Hz
Medium frequency range: 50Hz~1kHz
Medium and high frequency range: 1KHz~10kHz
High frequency range: 10kHz~200kHz 3. Adjustable output frequency
Cycle T=0.7 (RA+2RB) C
VR1 and VR2 are adjustable from 0-10K
At low frequency range, C=0.001UF
Mid frequency range:C=0.1UF
Medium and high frequency range:C=1UF
High frequency range:C=100UF
Therefore, the frequency of the waveform can be calculated by the buyer themselves
