Features
-Size:3.5CM * 3.6CM
-The main chip:NE555;
-Input voltage:5V-15VDC. 5V power supply, the output current can about 15MA; 12V power supply, the output current can be so 35MA;
-Input Current:100MA
-Output amplitude:4.2V V-PP to 11.4V V-PP (depending 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%)
Advantages
-Output with LED indication, there is no output LED quantity (low straightforward, high level LED off relatively low frequency LED flashes);
-Output frequency range grade optional continuously adjustable output frequency;
-Low-frequency stall:1Hz ~ 50Hz
-IF stall:50Hz ~ 1kHz
-In the high-frequency stall:1KHz ~ 10kHz
-High-frequency stall:10kHz ~ 200kHz
-the output duty cycle can fine-tune the duty cycle and frequency is not adjustable separately adjust the duty cycle will change the frequency
-the output frequency is adjustable;
-Cycle T = 0.7*(Ra + 2*Rb)*C
-Ra, Rb:0-10K adjustable;
-LF gear C = 0.001UF;
-IF file C = 0.1UF;
-In the high-frequency file C = 1UF;,
-High-frequency gear C = 100UF, the waveform frequency buyers can own calculations.
NOTE:Output duty cycle can fine-tune the duty cycle and frequency is not adjustable separately adjust the duty cycle will change the frequency
