OWON SPM3103 - 10amp DC Lab Power Supply with Integrated Multimeter

Maximize your workspace efficiency and measurement precision with the OWON SPM Series Simple Source Measuring Unit. This innovative 2-in-1 instrument combines a high-performance programmable DC power supply with a precision digital multimeter, offering a compact, solution-oriented tool for laboratories, production lines, and educational facilities.

Designed for engineers and technicians who demand versatility without compromising on performance, the SPM Series streamlines your workflow by allowing you to power a circuit and measure its parameters simultaneously. Whether you are conducting standard circuit testing or performing complex micro-resistance measurements, the SPM Series is your collaborative partner in precision.

Key Features & Benefits

• Dual-Functionality (Source + Measure): Eliminates the need for separate devices by integrating a stable DC power source with a high-accuracy multimeter. This "Simple Source Measuring Unit" design saves bench space and reduces equipment costs.

• High-Precision Power Output:

  • Models Available: (e.g., SPM3103: 0-30V / 0-10A / 300W).

  • Fine Control: Features high resolution (10mV/1mA) with low ripple and noise, ensuring clean power delivery for sensitive electronics.

  • Advanced Protection: Built-in Over Voltage Protection (OVP) and Over Current Protection (OCP) ensure your device and the Device Under Test (DUT) remain safe during operation.

• Integrated Digital Multimeter:

  • Capable of measuring Voltage (AC/DC), Current (AC/DC), Resistance, Capacitance, Diodes, and Continuity.

  • High Resolution: Delivers precise readings (e.g., up to 4½ digit resolution or similar depending on mode), essential for detailed circuit analysis.

• Advanced Testing Applications:

  • Micro-Ohm & Winding Resistance Testing: The SPM Series excels at specialized tasks. By setting the power supply to a constant current (CC) and using the multimeter to measure voltage, you can perform precise low-resistance measurements.

    • Example Application: Set the constant current to 10 Amps and measure the voltage across a transformer winding. This setup allows you to read with 1 µΩ resolution (displayed as 0.01 mV).

    • Simplified Reading: Set the constant current to 1 Amp, and the voltage reading directly correlates to ohms (V = IR), allowing for instant, calculation-free resistance checks.

• Intelligent Control & Connectivity:

  • Remote Operation: Supports SCPI commands for remote programming and automated testing systems.

  • PC Software: Control the unit and log data via the dedicated OWON SPM PC software through the standard USB interface (LAN/RS232 optional on select models).

  • List Waveform Editing: Edit and output custom voltage/current waveforms (up to 10 points) for simulating various power conditions.

• User-Centric Interface: Features a clear 2.8-inch TFT LCD color display capable of showing power supply settings and multimeter readings simultaneously. Simple knob and button controls allow for quick adjustments and shortcut storage (M1-M4 memory keys).
