TASI TDB Series Adjustable DC Power Supply is a high-precision regulated power supply featuring constant voltage (CV) and constant current (CC) operation, with multiple output options ranging from 15V/5A to 100V/3A. As an adjustable DC power supply, laboratory power supply, variable power supply, bench power supply, and electronic test power source, it is widely used in R&D laboratories, electronics manufacturing, production line testing, industrial maintenance, automation systems, educational training, PCB testing, automotive electronics, communication equipment and component inspection applications. The TDB Series supports automatic switching between constant voltage and constant current modes, providing precise and continuous adjustment of output voltage and current. With high setting resolution, low ripple output and excellent stability, it delivers reliable DC power for electronic components, circuit boards, sensors, modules and various electronic devices requiring accurate power control. Equipped with built-in Over Voltage Protection (OVP) and Over Current Protection (OCP), the power supply allows users to set protection thresholds according to different applications. When abnormal output conditions occur, the system quickly disables the output to protect the connected devices and the power supply itself. The TDB Series supports three groups of parameter storage (M1/M2/M3), allowing users to save and recall frequently used settings for efficient repeated testing. The integrated RS232 communication interface enables connection with computers and automated test systems for remote control, parameter configuration and data acquisition, making it suitable for smart manufacturing environments. The high-resolution digital display provides real-time voltage, current and power readings simultaneously. Combined with adjustment knobs, function keys, output control and parameter lock functions, the operation is simple and efficient. With compact construction, forced cooling design and a 0–40℃ operating temperature range, the TDB Series is ideal for laboratory experiments, electronic product development, production line aging tests, repair stations and professional testing applications.
