Educational power supply

stablized voltage power supply StableDC output 1V-25V/6A4A2A,with ammeter; AC output 2V-24V/12A6A3A, short current is 40A DC timed output limit.All the outputs are overload-protection. 1.AC output Nominal voltage: total is twelve grades, 2-24V, each grade is 2V. Rated current: 2-6V grade is 12A, 8-12V grade is 6A, 14-24 grade is 3A. Unload voltage: power supply voltage is 220V. Each grade 1.05Usuperscript+0.3V. Full-load voltage: power supply voltage is 220V, and output current is 5A. Each grade 0.95Usuperscript-0.3V. 2.DC stabilized output Nominal voltage: 1-25V can be continuous adjustable. Adjust 2-24V finely. Each grade is 2V and can adjust ±1V finely. Rated current: 2-6V grade is 8A, 8-12V grade is 4A, 14-24V grade is 2A. Voltage modulation: ± (2%Usuperscript+0.1V). Voltage stability: 2% +0.1V. Load stability: 2% +0.1V. Ripple coefficient: 1%. Precision of voltmeter: 2.5grade. 3.Overload protection: The power supply will stop automatically when the output current is 1.05-1.5times of rated current. Meantime, it can start the filament lamp is not more than rated current. 4.Short-term output of DC current Output current: 40±10A (short-term) Timer time: 8±1S, it will close automatically. Power supply input: AC220V±10% 50HZ
