Auto Fuse for power supply
The power supply, with electronic stabilization - mainly those of laboratories - should be protected from overcurrent that emanates from short-circuits, erroneous association, or damage of repaired appliances. The circuit offers effective protection in power supply with output voltage up...
variable voltage and current power supply
An alternative method for utilizing operational amplifiers (op-amps) to regulate a power supply is illustrated below. The power transformer necessitates an additional winding to provide the op-amps with a bipolar voltage of +/- 8 volts. This negative voltage is also...
-15 V 1-A Regulated Power Supply
The supply receives -20 V from the rectifier/filter which is fed to the collector of the Darlington pnp pass transistor, a TIP105. The base drive to the TIP105 is supplied through resistor R5. The base of the TIP is driven...
100v / 10ma regulator circuit
The circuit features no-load and short circuit protection mechanisms. To accommodate short circuit conditions, it is necessary to increase resistors R1 and R2 to allow for power dissipation; for example, R1 can be set to 1.2kΩ with a power rating...
Eng Sony AV 3400
The original power supply AC-3400 features a charger function. In addition to the power button and the indicator light for power status, the front panel includes a charge level indicator for the accumulator, a start button, and a socket for...
