Power Supply and Multimeter in One
Integrates a programmable DC power supply and 4½-digit digital multimeter for voltage, current, resistance, capacitance, diode, and continuity measurements. One unit handles power delivery, measurement, and debugging.
500 W Constant-Power Output
The series covers 150 W to 500 W, with output up to 80 V/20 A and flexible voltage and current combinations within the rated power. All models provide 10 mV/1 mA setting resolution, while the 80 V models offer voltage accuracy of ≤0.05% ± 20 mV and a response time of ≤5 ms.
Multiple Protections and Automatic Output
OVP, OCP, and OTP protections combine with intelligent CV/CC switching to automatically enter CC mode when the load current exceeds the limit. An independent output switch and configurable automatic output 5 seconds after power-on support circuit safety and unattended testing.
LIST Programming and Quick Parameter Recall
Ten 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 Output Curve Monitoring

Monitors voltage and current output curves for a clear view of changing trends. Suitable for smartphone and laptop repair, PCB burn-in testing, and battery charge/discharge experiments.
Multiple Interfaces and Remote PC Control
All models include USB Device and USB Host interfaces and support SCPI for remote control via PC software. On the SPM8104 and SPM8205, RS232 is available as an alternative to USB Device for automated testing and system integration.
