Feature
Size 31CM 22CM
The main chip NE555
Input voltage 5V15VDC 5V power supply the output current can 15MA around 12V power supply the output current can 35MA around
The input current 100MA
The output amplitude 42V VPP to 114V VPP Different depending on the input voltage the output amplitude will be different
The maximum output current 15MA 5V power supply VPP greater than 50 35MA 12V power supply VPP greater than 50
Advantages
1 the output with LED indication there is no output straightforward low LED volume high LED off frequency is relatively low the LED flashes
2 the output level selectable frequency range the output frequency is more continuously adjustable
LF file 1Hz 50Hz
IF file 50Hz 1kHz
Highfrequency file 1KHz 10kHz
HF file 10kHz 200kHz
3 the output duty cycle can finetune duty cycle and frequency is not separately adjustable adjusting the duty cycle will change the frequency
4 the output frequency is adjustable
Period T 07 RA 2 RB C
RA RB is 010K adjustable
Low profile when C 0001UF
IF stalls C 01UF
Highfrequency file C 1UF
HF stalls C 100UF
Note The size is manually measured there is an error of 15mm
