When buttons or knobs of a DC stabilized power supply fail (e.g., no response when pressing buttons, inability to adjust voltage/current via knobs, or failure to switch CV/CC modes), you can troubleshoot and resolve the issue by following the step-by-step guide below, starting with simple checks and moving to targeted repairs: I. Preliminary Quick...

Parallel Mode: Expansion Solution for High-Current Output 1. Core Definition & Application Scenarios In parallel mode, the output terminals of the two power supplies are connected in parallel, making the total output current equal to the sum of the two channels (I_total = I1 + I2). The voltage is controlled by the master channel...

Series Mode: Expansion Solution for High-Voltage Output 1. Core Definition & Application Scenarios In series mode, the output terminals of the two power supplies are connected in a specific way, making the total output voltage equal to the sum of the two channels (U_total = U1 + U2). The current is determined by the...

Independent Mode: Basic Mode for Differentiated Power Supply 1. Core Definition & Application Scenarios Independent mode is the most basic working mode of dual-channel power supplies. The two output ports (CH1, CH2) are fully independent, with voltage and current parameters adjustable separately without mutual interference. It is suitable for simultaneous power supply to loads...

DC regulated power supplies are prone to various issues during use, such as abnormal output, false triggering of protection mechanisms, and adjustment failures. These problems are mostly related to wiring, internal components, and load matching. Below are common high-frequency faults and their corresponding detailed solutions, integrating the common fault scenarios of multiple devices: 1....
