We will consider a laboratory power supply from GVDA 30 volts and 10 amps in a vertical design. Its maximum power is 300 watts. It can be used as a constant voltage and constant current source. This power supply will be useful:
1. Conducting various experiments and experiments with electronics, automation and electrics.
2. Charging various batteries, including car batteries.
3. Use as a temporary power source for those devices whose power supplies have burned out.
4. Calibration of devices for voltage and current.
