The fish farming oxygen increasing controller circuit is composed of the power supply circuit and control circuit, and it is shown in Figure 4-21. Power supply circuit is composed of the power switch S, power transformer T, rectifier diode VDl-VD4 and filter capacitor Cl. Control circuit consists of transistors Vl, V2, relays Kl, K2, resistors Rl-R4, capacitors C2, C3 and diodes VD5, VD6. RI-R4 select the 1/4W carbon film resistors or metal film resistors. Cl uses the aluminum electrolytic capacitor with voltage in 35V; C2 and C3 select the aluminum electrolytic capacitors with voltage in 25V. VDI-VD6 use 1N4007 silicon rectifier diodes. Vl and V2 choose C8050 or S8050 silicon NPN transistors.
