The OWON OWH67 programmable DC power supply series is a high-power solution for applications that require configurable DC output in laboratory or industrial settings. OWON introduced the series as part of its expansion in industrial-grade power supply technology. Its combination of rack-oriented construction, wide-range constant-power operation, and precise output settings makes it relevant where voltage and current requirements can vary during testing or equipment operation.
Overview of the OWON OWH67 Series
The OWH67 series is built in a 1/2 2U standard rack size. This format supports rack-mounted installations, helping users integrate the power supply into organized test setups or equipment racks. Output connections are available on both the front and rear panels, which can provide practical access options based on the installation layout.
OWON lists maximum output power options of 1200W, 2000W, and 3000W for the series. These options allow users to consider a power level suited to the needs of a particular application without assuming that every configuration has the same output capability.
Constant-Power Output for Flexible Operating Ranges
A key characteristic of the OWH67 high-power programmable DC power supply series is its wide-range constant-power design. The published output range reaches up to 150V/30A. Within the constant-power output limit, voltage and current can be combined more flexibly than with a fixed, single-point output approach.
For test environments, this can be useful when a workflow requires changes in the voltage-to-current balance while remaining within the applicable constant-power limit. Users should select and operate a power supply according to the requirements and limits of their own load, test procedure, and installation.
Output Setting Precision
The OWH67 series offers output setting precision of 10mV/1mA. Fine setting increments can be important in work that calls for deliberate adjustment of DC output values, including laboratory development activities and industrial test tasks. This specification describes output setting precision; it should not be interpreted as a broader measurement or system-performance specification beyond the information provided for the series.
When evaluating a programmable DC power supply, it is useful to distinguish required voltage range, current range, total power, physical installation, and setting resolution. The OWH67 series addresses these considerations through its stated power options, output capability, rack-compatible dimensions, and 10mV/1mA setting precision.
Rack Installation and Output Access
Rack mounting is a central part of the OWH67 design. The 1/2 2U standard rack size is intended for installations where bench space, panel access, and equipment organization need to be considered together. Having outputs on the front and rear panels may help accommodate different wiring arrangements, whether access is needed from the operator side of a rack or from the rear of an installed system.
Before installation, users should assess the planned rack arrangement and ensure that output access aligns with the intended workflow. The front and rear output arrangement is a product feature, while the best connection method depends on the specific application.
Temperature-Controlled Fan Operation
The series uses an intelligent temperature-controlled fan. OWON states that this fan design reduces noise and supports quieter operation in laboratory and industrial environments. This can be a meaningful consideration for workplaces where equipment is used near personnel or where minimizing unnecessary operating noise is preferred.
The OWH67 series therefore brings together high-power options and practical installation features without positioning noise reduction as a substitute for normal thermal planning. Appropriate operating conditions and system integration remain important for any rack-mounted power equipment.
Choosing an OWH67 Series Configuration
Selection starts with the power requirement: the available series options are 1200W, 2000W, and 3000W. Next, confirm that the needed operating point falls within the published range of up to 150V/30A and within the relevant constant-power limit. Finally, consider the rack layout, the preferred front or rear output access, and whether the 1/2 2U standard rack format fits the available installation space.
For laboratories and industrial operations seeking a programmable DC source with a wide-range constant-power design, the OWON OWH67 series presents a focused set of published capabilities. Its rack-ready form factor, output accessibility, precise settings, and temperature-controlled fan are the main points to review against the demands of the intended application.
