Product Name: HJS-480-0-120 0-120V4A Switching Power Supply 0-4800W 0-5V Signal Control Voltage
Input voltage: AC110/220V ± 15%
Output voltage: DC0-120V4A
Rated power: 480W
Product size: 21.5CM (length) * 11.5CM (width) * 5CM (height),
instructions:
(No matter how high the voltage is adjusted to, the current is 4A, and the current cannot be adjusted. The actual current is determined by the load). Any device with a current less than 4 can be used, and any device with a current greater than 4A cannot be used
Usage: Mainly used for various DC devices, DC motor stepless speed regulation, LED stepless dimming, chemical electrolytic plating speed regulation, scientific research testing, student experiments, etc., with a wide range of applications.
Special attention: When using inductive loads such as motors and fans, please pay attention to the high starting current parameter of the motor. This parameter should not be higher than the high operating current of the power supply, otherwise it may cause damage to the power supply. You should choose a power supply with a higher current or equip the motor with a soft start protection circuit to absorb the surge current.
(Power formula) Voltage X current=power
For example, when connected to an 80V3A device, the power is 240W, and when connected to a 120V2A device, the power is 240W
