Item Type:Pulse Frequency Generator <br>Size:2.9 x 3.6cm / 1.14 x 1.42in <br>Fixing Hole Distance:22.5 x 30.5mm / 0.89 x 1.2in <br>Main Chip:NE555 <br>Input Voltage:5V~15VDC.When 5V is supplied, the output current can be around 15mA; when 12V is supplied, the output current can be around 35mA. <br>Weight:Weight: 10 g / 0.35 oz(approx.) <br>Input Current:>=100mA <br>Output Amplitude:4.2V V-PP to 11.4V V-PP. (The output amplitude will be different depending on the input voltage) <br>Output current: ≥15mA (5V power supply, V-PP is greater than 50%), ≥35mA (12V power supply, V-PP is greater than 50%) <br> <br>Output Frequency: <br>Low Frequency: 1Hz ~ 50Hz <br>Intermediate Frequency: 50Hz ~ 1kHz <br>Medium And High Frequency: 1KHz ~ 10kHz <br>High Frequency: 10 KHz ~ 200 KHz <br> <br>Period T = 0.7 (RA + 2RB) C <br>RA and RB are adjustable from 0 to 10K; <br>C=0.001UF in low frequency gear; <br>C=0.1UF in the intermediate frequency file; <br>Medium and high frequency file C=1UF; <br>C=100UF in high frequency, so the frequency of the waveform can be calculated by yourself.<br>1、Output with LED indication,when the LED is low, the LED is off, and when the frequency is low, the LED is blinking,more clear and convenient. <br>2、Output frequency range grade is optional,use the shorting cap to select) to make the output frequency more continuously adjustable. <br>3、Generate square wave signal, adjustable pulse. <br>4、Compact and practical design makes it works more stable. <br>5、Widely applicable to multiple occasions,suitable for many equipments.1 x Signal Generator
