This is a new 24 Volt DC power adapter. This is a high quality regulated power supply. The universal voltage input is 100 to 240 Volts AC at 50/60 Hz. The output is 24 volts DC at 1200ma (1.2 Amps). The power supply has a right angle plug. This power supply will replace 24 Volt DC power supplies that are rated at .1 to 1.2 Amps. So this a substitute for 24 VDC power supplies rated at 100mA, 200mA, 250mA, 300mA, 350mA, 400mA, 450mA, 500mA, 600mA, 650mA, 700mA, 750mA, 800mA, 900mA, 1000ma and 12000mA. 

These power supplies are commonly used with LED light strips, routers, computer case fans, humidifiers, LCD monitors, massagers and Bluetooth speakers.
