1. * * High precision and high stability**

-Accuracy and Resolution: Multiple models (such as HSPY 600-01 and HSPY 1500-0.2) have a set value accuracy of 0.1%, a voltage resolution of up to 10mV/1V, and a current resolution of 1mA/0.1mA, meeting high-precision testing requirements.

-Low temperature drift: The overall temperature drift of the machine is less than 50ppm, ensuring stable output at different ambient temperatures.

-* * Load Adjustment Rate * *: The voltage load adjustment rate is as low as 0.02%, and the current is 0.02%, further ensuring output stability.

### 2. **Flexible multi-mode operation**

-Multi mode exchange: Supports constant voltage (CV), constant current (CC), constant power (CP), and energy calculation modes to adapt to different testing scenarios.

-* * Programmable Function * *: Built in Modbus communication protocol, supports remote control through PC or PLC, and achieves automation system integration.

### 3. **Innovative power structure design**

-* * Switching+Linear Combination * *: The front stage uses a switching power supply to improve efficiency, while the rear stage uses a linear power supply to reduce ripple (ripple ≤ 5mVrms), balancing high efficiency and low noise, solving the problem of low efficiency or large ripple in traditional power supplies.

-* * Fanless/Temperature Controlled Design * *: Some models (such as HSPY 1500-0.2) use temperature controlled fans to regulate temperature, while low-power models (such as the old model mentioned on website 6) use fanless design to reduce noise interference.

### 4. **Safety and Convenience**

-* * Protection Function * *: Built in overload, short circuit, and overheating protection circuits ensure safe operation of the equipment.

-Memory storage and locking: Supports saving the last shutdown parameters and preventing accidental operations through the software lock panel.

-* * Portable Design * *: Multiple models are compact in size (such as HSPY 60-03 with dimensions of 185 × 85 × 120mm and weight of 1.45kg), suitable for laboratory and mobile scenarios.

### 5. **Widely applicable fields**

-Suitable for research laboratories, production line testing (such as electronic component testing, battery performance testing), communication equipment debugging, and automotive electronics.

-High voltage models (such as HSPY 1500-0.2 output 0-1500V) meet special high-voltage testing requirements.

### 6. **Customization and technical support**

-Provide non-standard customized services, adjust parameters and functions according to customer needs.

-Comprehensive after-sales support, including one-year warranty, lifetime maintenance, and professional technical guidance.
