NE555 Pulse Module Frequency Duty Cycle Adjustable Square Signal Generator

Descrição de NE555 Pulse Module Frequency Duty Cycle Adjustable Square Signal Generator

Features: 1.Main chip: N5555;Input voltage: DC5-15V; Output amplitude: 4.2V V-PP(5v input) to 11.4V V-PP(12V input); Output frequency 1Hz-50Hz, 50Hz-1KHz, 1KHz-10KHz, 10KHz-200KHz Four Optional. 2.When power supply is 5V, the output current can be 15MA around;when 12V power supply, the output current can 35MA around. 3.Output amplitude: 4.2V V-PP to 11.4V V-PP. (Different input voltage, the output amplitude will be different). 4.Maximum output current 15MA, included 15MA (5V power supply, V-PP greater than 50%), >=35MA (12V power supply, V-PP greater than 50%). Output with LED indication(low level ,LED will on; high level,LED will off;low frequency, the LED flashes). 5.The output duty cycle can fine-tune. Duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency. Package Includes: 1 Piece NE555 Module Specifications: Material: ABS Color: As picture shown Input Current: >100MA ( included 100MA ) Input Voltage: 5V-15VDC LF File: 1Hz ~ 50Hz IF File: 50Hz ~ 1kHz High Frequency File: 1KHz ~ 10kHz HF File: 10kHz ~ 200kHz Cycle T=0.7 (RA+2RB) C (RA, for RB for 0-10K adjustable) Low Frequency: C=100UF Intermediate Frequency: C=1UF M-H Frequency: C=0.1UF High Frequency: C=0.001UF Size: Approx. 3.1x2.2cm/1.22x0.86in Weight: Approx. 12g note: 1.Before changing the frequency, please power off. 2.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid. 3.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
