This new S-600W-12V switching power supply converts the input voltage 110V/220V 1% to DC12V, 0-50A, maximum 600W output voltage, error is 5%; output current; output current;Depending on the requirements of electrical equipment, it is suitable for supplying multiple different current/equipment.Tile AC input range is switched by switching, using new components and glass fiber board circuits; high -quality electrolytic capacitors, high -frequency and low resistance, pure voltage environment, more efficient operation, more stable voltage and longer uselife. We specially adjusted the switch to 110V/115V, suitable for American users.If you want to use AC220V, adjust the switch to the 220V side before use.There is a voltage selection switch on the side of the switch to set the input voltage of the power supply to 110V/115V or 220V/230V.Meet multiple use conditions There are 4 protection of this equipment: short -circuit/overload/overcurrent/overheating protection.The working environment is between -10 C and 70 C.Built -in filter, low output , low noise, sturdy and shells, after testing, 100% full -loading aging.Can be parallel/redundant operation Plug Type: US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the , the Philippines and so on.
