500 V High-Voltage Output with Precision and Fast Response
The series offers 150 V, 300 V, and 500 V output ranges with 400 W and 500 W power ratings. A DSP main control chip and a 24-bit high-precision ADC provide excellent signal acquisition resolution and measurement accuracy.
Lightweight Design with a Clear Display
The compact, portable design features a 2.8-inch IPS color LCD with high contrast and excellent visibility. Waveforms and parameters remain clear in both bright and dim environments for easier operation and faster reading.
LIST Programming and Quick Parameter Recall
10 built-in timed output steps automatically run sequences with preset voltage, current, and dwell time. PC software expands the sequence capacity to 100 steps, while four Memory presets enable one-touch parameter recall.
Real-Time Curve Monitoring
Displays voltage and current curves in real time and logs up to 1 minute of operating data, helping users quickly capture abnormal fluctuations.
Multiple Protections and Safe Discharge

OVP, OCP, OTP, and automatic discharge release residual energy when the output is turned off. Combined with intelligent CV/CC switching and smooth power-on, these features improve high-voltage test safety and reliability.
Smooth Power-On for Enhanced Reliability
Provides 10 mV/1 mA setting and readback resolution, accuracy as tight as 0.05%. Minimal voltage and current overshoot during power-on helps protect sensitive devices and improves startup safety and reliability.
PC Control and Industrial System Connectivity
Supports PC programming and remote control. USB Device is standard, with optional RS232, RS485, or LAN interfaces. SCPI and Modbus compatibility simplifies automated system integration.
