- 18-36 power control
This power supply circuit is adjustable 18-36 volts and is currently shown as being limited to 2 amps, but up to 3 amps in a small current sense resistor of Options (0.3 ohm). 2N3055 and 2N3053 transistors should be in wells. very hot right now and resistance is to be made at 3 watts or more. Voltage, which is controlled by 1 / 2 of the LM1458 Op Amp, or 1458-AMP. It can be replaced in the circuit below, but sources indicate pressure. Pin 8 to 30 VDC supply is limited, which may increase by 6.2 Vdc or 5.1 Vdc. Zener K-series resistance, is 8-pin. Maximum supply voltage DC for LM1458 and LM1558 are 36 and 44, respectively.
Should be the power transformer. As expected the power supply. Enter at least 4 times the desired output voltage, but can not exceed the op-amp under conditions of low stress. Transformer is used as a center, see 25.2 volts AC / AMP 2 units to regulate the 24 volts at 0.7 amps, 15 volts at 2 amps or 6 volts at 3 amps. Output AMP 3 is the center of the water. Transformer that changes the position of 18 volts. All components must be an exception from Radio Shack LM1458 op-amp.
