OWON SPM Programmable DC Power Supply Multimeter up to 500W

The OWON SPM Series combines a single-channel programmable DC power supply and a 4.5-digit digital multimeter in one compact instrument. With output configurations from 150W to 500W, the series supports powered-device development, laboratory verification, maintenance, education and automated power testing.

Integrating source control and independent electrical measurements reduces bench space and the need for a separate multimeter. List output programming, voltage and current curve monitoring, protection functions and computer control provide an efficient platform for repetitive test sequences and changing-load investigations.

Key Features

• DC source and multimeter integration: Supply power to a device under test and perform voltage, current, resistance, capacitance, continuity and diode measurements from the same instrument.
• Single-channel output up to 500W: The expanded series covers general circuit development as well as applications requiring higher voltage, current or total output power.
• 10mV and 1mA setting resolution: Apply controlled voltage and current changes during component evaluation, device verification and educational experiments.
• List waveform output: Create sequenced power profiles for startup testing, repetitive verification and changing supply-condition simulation.
• Ten editable timing groups: Configure multiple output stages without manually changing the voltage and current at every test step.
• Voltage and current curve monitoring: Observe output behavior over time to identify changes during startup, operation and load transitions.
• OVP and OCP protection: Set overvoltage and overcurrent limits to help protect the power supply and connected device during testing.
• Four stored output groups: Save frequently used power settings for faster setup during repeated laboratory tasks.
• 4.5-digit auto-ranging multimeter: Perform common electrical measurements without occupying additional bench space with a separate meter.
• USB and SCPI control on 150W–300W models: Connect these models to a computer for remote operation and integration into automated test workflows.
• Interface selection on higher-power models: The SPM8104 and SPM8205 are supplied with USB Device as the default communication interface or can be configured with RS232, allowing the interface to match the intended system environment.
• Compact 2.8-inch color display platform: View source settings, measured values and output curves from a space-efficient instrument.

Applications

• Electronic circuit development and powered-device debugging
• Power supply startup and sequence testing
• Automated production and repetitive verification
• Component, module and embedded-system evaluation
• Laboratory measurement and educational experiments
• Maintenance and repair of electronic equipment
• Voltage and current trend monitoring

Why Choose the OWON SPM Series?

The SPM Series is suited to users who need programmable power, electrical measurements and sequence testing in a compact platform. The 150W and 300W configurations address general electronics development and automated bench testing with USB and SCPI control. The SPM8104 extends the range for applications requiring up to 80V or 10A, while the SPM8205 supports higher-current work up to 20A and 500W. For these higher-power models, the required USB Device or RS232 communication configuration should be selected to match the control system.
