Han Shengpusource30V5AAdjustable DC stabilized power supply is a precision programmable power supply that integrates high precision, multi-mode, portability, and intelligence. It is designed specifically for laboratory research and development, electronic testing, industrial debugging, and other scenarios. itswith“Small volume, large energy, multifunctional and stable transmissiongo out”As a core advantage, the practical standards for small and medium-sized power supplies have been redefined through innovative technology and user-friendly design. The following are the core product features:

1、 Lightweight and portable, worry free when traveling

Different from traditional large volume power supply devices, this product adopts a compact structural design, with a body size of onlyfor185×85×120mm（aboutA4Paper horizontalto, toward, at, facing1/3Size, overall weight of the machineonly 1450Ke（about1.45kg, equivalent to a large bottle of mineral water), truly solidnow“One palmgrip”Whether it is laboratory desktop movement, production line workstation switching, or outdoor testing carrying, it can be easily handled, greatly reducing space occupation and transportation burden.

2、 Multi mode flexible switching, one machine for multiple purposes

Breaking through the limitations of a single constant voltage function, supporthold constant voltage（CV）Constant current（CC）Constant power（CP）And electric energy metercalculate Multiple working modes can be freely switched. For example, during the research and development phase, when precise voltage control is required, the constant voltage mode should be selected; Switching constant current protection when testing load limit current; Enable constant power mode when optimizing energy efficiency; In long-term experiments, power consumption data can also be calculated through the electric energy calculation function. One machine covers multiple application requirements, significantly improving tool reuse rate.

3、 Minimalist user interface, intuitive and efficient

pickuse“Simple and cleanuse”The interaction logic and clear interface layout are divided into sections:

- Window display: high-definition LCD screen with four digit display, real-time synchronized presentationnow electricitypress/The set value and output value of the current (such asfixed3.3V/2A, losego out3.29V/1.98AAt a glance, accurately label the current output power to avoid manual conversion errors;

- Operation method: Supporthold Accurate key inputenter+The shuttle knob can be quickly adjusted (replacing traditional potentiometer fine-tuning), allowing for direct input of target values through buttons (such as input)enter“5.00V”One step in place), it can also rotate the shuttle quickly and roughlytune/Fine tuning to significantly improve parameter setting efficiency;

- Intelligent assistance: Built in status indicator lights and error code prompts, real-time feedback of power supply working status (such as overvoltage and overcurrent protection triggering), reducing the operating threshold.

4、 Intelligent temperature control and stable output guarantee

- Dynamic heat dissipation management: adopting temperature control fan adjustment technology, automatically starting and stopping or adjusting the speed according to the internal temperature (low-speed silent operation under low load, accelerated heat dissipation under high load), reducing noise interference while ensuring heat dissipation efficiency;

- CPUReal time tracking: Continuously monitor output parameters through high-performance microprocessors, dynamically correct deviations, and ensure long-term power supply during operationpress/current valueof High stability (whole machine temperature drift)＜50ppm, accuracyreach0.1%）Meet the power supply needs of precision instruments;

- Zero impact protection: uniqueof The two-stage adjustable voltage regulation topology circuit structure effectively suppresses the surge current during the switch on/off, avoids impact damage to sensitive loads (such as chips and sensors), and extends the service life of the tested equipment.

5、 High precision and low ripple, reliable data

- Core performance indicators:

- Voltage precisiondegree 0.1%(The deviation between the set value and the actual output is extremely small), distinguishrate10mV/100mV(Supporting fine adjustment);

- Electric current precisiondegree 0.5%, distinguishrate1mA/10mA(Meet the requirements of low current scenarios);

- Extremely low ripple and noise (electric)press≤2mVrms, Electricityflow≤3mArms）Pure output close to linear power supply, avoiding high-frequency interference affecting test results;

- Environmental adaptability: Low temperature float design（＜50ppm/℃）Even in laboratory environments with temperature fluctuations, long-term consistency of output parameters can still be maintained.

6、 Intelligent Memory and Security Protection

- Memory storage function: automatically saves the last set power before shutdownpress/The current value does not need to be repeatedly set during the next startup, saving debugging time;

- Anti misoperation design: Built in software locking function, which can remotely lock panel buttons through computer software (such as laboratory public equipment anti misoperation), or lock current parameters through physical buttons, improving usage safety;

- Dual protection mechanism: It has multiple protections such as overvoltage, overcurrent, overheating, and short circuit. In case of abnormal situations, it automatically cuts off the output and gives an alarm prompt to protect the safety of the power supply and the tested equipment.

7、 Flexible control and system compatibility

- Convenient adjustment experience: Abandoning the shortcomings of traditional potentiometers such as easy wear and inaccurate adjustment, adoptinguse presskey+Flying shuttle knob combination adjustment, balancing precise input and quick adjustment requirements;
