The electronic rodent repeller circuit diagram 3

Published:2011/6/30 5:35:00 Author:Lucas | Keyword: Electronic rodent repeller | From:SeekIC

The electronic rodent repeller circuit is composed of the power transformer T, diodes VD1 ~ VD6, transistors V1 and V2, thyristor VT, relay K, alarm HA and electrode and so on, and the circuit is shown as the chart. R1 ~ R3 use of 1 / 417 carbon film resistors. C1 and C2 select aluminum electrolytic capacitors with the voltage in 16V. VD1 and VD3 ~ VD5 use 1N4007 silicon rectifier diodes; VD2 uses 1N5408 silicon rectifier diode; VD6 uses 1N4148 silicon switching diode. V1 selects 59012 silicon PNP transistor; V2 selects 59013 silicon NPN transistor. VT selects MCR100-6 thyristor. K selects 6V DC relay. HA selects the speakers or alarm bell with higher loudness . Adjusting the R1 can alter the conduction sensitivity of VT.
