Power Supplies
Programmable DC power supplies from compact bench units to 7.2 kW high-power and bidirectional models — single- and multi-channel with SCPI remote control.
Professional OWON power supplies category introduction
OwonTechnology.eu supplies genuine OWON power supplies for European customers, with EU shipping, manufacturer warranty and local support. Main ranges include OWH67 High-Power Series, SPE / SPE-U Programmable, SPM Power Multimeter, SP / P4000 Linear Series, SPS Fanless / 1-CH + Rails, 2-CH with Fixed 5V, 3-CH Programmable. Choose by the required technical range, application, connectivity and measurement accuracy.
- High-power testing: Choose the OWH67 series (1200–3000 W) or OWH6522 (60 V / 120 A) when high current or total wattage is needed — battery cycling, motor drives and energy-storage characterisation.
- General bench programmable: Choose the SPE/SPE-U series for everyday programmable DC work — compact format, wide voltage and current range options, SCPI over USB or LAN.
- Bidirectional / regenerative: Choose the OWH67B when the supply must also sink current — charge/discharge cycling, regenerative test rigs and two-quadrant characterisation in one instrument without a separate electronic load.
- High-voltage output: Choose the SPE High Voltage (up to 540 V) or OWH6546 (up to 546 V) for applications requiring elevated DC voltage — component testing, dielectric withstand and HV device characterisation.
- Fanless / noise-sensitive: Choose the SPS Fanless series when acoustic or EMI noise from a fan would interfere with the application — measurement benches, audio equipment and clean-room environments.
- Multi-channel / digital development: Choose an ODP dual- or triple-output supply when multiple independently controlled rails are needed — mixed analogue/digital benches benefit from the fixed 5 V and 3.3 V logic rails alongside the main programmable output.
Power Supplies from OWON
The OWON power-supply range covers every major bench and production need: compact linear single-channel units for general electronics work, programmable switching SPE-series supplies for applications requiring precise voltage and current with PC control, and high-power OWH67 series models up to 3000 W — and the OWH6522 at 60 V / 120 A for battery, motor and energy-storage test systems. Multi-channel variants add fixed 5 V and 3.3 V logic rails alongside the main programmable output, covering digital development benches in a single instrument.
All programmable models support USB and LAN connectivity with full SCPI compliance for integration into automated test environments. The OWH67B bidirectional series operates as both a DC source (CC/CV/CP) and a DC load (CC/CV/CR/CP) from a single instrument — the practical choice for battery charge/discharge cycling, regenerative test systems and two-quadrant power characterisation. The SPM series adds source-measure capability with built-in voltage, current and power readback.

Questions about OWON Power Supplies
Technical selection guidance for choosing the right instrument family and model.
What is the difference between the OWH67, SPE and SP/P series?
The OWH67 series are high-power switching supplies (1200–3000 W) designed for demanding loads like battery test systems and motors. The SPE/SPE-U series are compact programmable bench supplies (100–500 W) for general lab and development use, with SCPI over USB and LAN. The SP/P4000 series are lower-power linear units (up to 180 W) suited to low-noise applications where switching ripple must be minimised.
What does bidirectional mean on the OWH67B?
The OWH67B can operate as both a DC power source (constant-current, constant-voltage or constant-power mode) and a DC electronic load (CC/CV/CR/CP) from a single instrument. This makes it suitable for battery charge/discharge cycling, regenerative test systems and two-quadrant power characterisation without needing a separate electronic load.
Which OWON power supplies support SCPI remote control?
All programmable models — OWH67 series, SPE/SPE-U, SPM and multi-channel variants — support SCPI over USB and LAN, allowing full remote control and automation from a PC or test script. The linear SP/P4000 series is manually controlled and does not include a remote interface.
When should I choose the SPM power multimeter over a standard supply?
Choose the SPM when you need both a programmable DC source and integrated measurement readback in one instrument — it combines a programmable supply with accurate voltage, current and power measurement, making it suitable for device characterisation, I-V curve tracing and source-measure unit (SMU) tasks.
