The DC Regulated Power Supply features a sturdy, thickened steel chassis that is both aesthetically pleasing and durable, with a convenient carrying handle for easy transport. It offers precise voltage and current control with both coarse and fine adjustment options. The device automatically switches between constant voltage (CV) and constant current (CC) modes, allowing it to function as both a constant voltage source and a constant current source. The power supply is equipped with comprehensive protection features, including over-voltage protection (OVP), short circuit protection (OCP), and over-temperature protection (OTP). It incorporates PWM switch pre-regulation and MOS linear adjustment mode for high efficiency, energy-saving, and environmentally friendly performance. Additionally, the intelligent temperature-controlled fan adjusts speed according to the load, reducing noise and extending the fan’s life. The unit is designed with SMD technology for enhanced stability and performance and is capable of continuous 24-hour full-load operation.
