For electronics manufacturing, development, and bench work where controlled DC output is required, a power supply is more than a source of voltage. It is part of the setup used to apply power, observe behavior, and manage operating conditions during a task. The OWON SPS fanless programmable DC power supply series is designed around these needs with a single-channel architecture, digital control, and fanless operation.
The series includes two models: SPS6051, with a maximum output power of 150W, and SPS3081, with a maximum output power of 120W. Both are presented as fanless programmable DC power supplies and use a constant-power design. This approach supports different voltage and current combinations as long as the selected operating point remains within the model's rated power range.
Overview of the OWON SPS Programmable DC Power Supply
DC power supply must not only provide a stable output but also allow operators to monitor, adjust, and protect the device under test. The OWON SPS programmable DC power supply series features a single-channel configuration, focusing on one output channel for powering devices and setting operating parameters according to specific requirements.
Constant-Power Design
The constant-power design allows flexible combinations of output voltage and current, provided that the selected combination remains within the rated power range of each model. This feature is useful when an application requires different power supply conditions, such as using a higher voltage with a lower current or vice versa. Before configuring the output, users should compare the load requirements with the output limits of the selected model.
Fanless Design for Reduced Noise
The fanless design is one of the key features of the SPS series. By eliminating the need for a cooling fan, the power supply can operate with lower noise, which is particularly useful when the equipment is positioned close to the operator or used in environments where mechanical noise needs to be minimized.
Even with a fanless design, the power supply should still be installed and operated under appropriate conditions to ensure adequate heat dissipation.
Output Resolution and Monitoring Functions
The OWON SPS programmable DC power supply provides output resolution down to 10 mV/1 mA. This level of control allows users to set voltage and current with finer adjustment steps, making it suitable for applications where changes in output need to be closely monitored during testing.
The SPS series also supports List waveform output editing. This function allows users to create a sequence of output changes based on predefined settings rather than maintaining a single fixed voltage or current level.
The power supply can also monitor voltage and current waveforms and record one minute of online data. These monitoring functions help operators track changes in the power delivery process throughout a test session.
Built-in Protection Mechanisms
Safety is an important consideration when supplying power to electrical circuits, components, or devices under test. The OWON SPS digital control system incorporates protection functions against overvoltage, overcurrent, input undervoltage, and overtemperature. These protection mechanisms are designed to enhance the safety of both the power supply and the connected equipment under abnormal operating conditions.
In addition, the output incorporates a built-in discharge circuit. When the power supply is turned off, this circuit helps eliminate the risk of high residual voltage remaining at the output terminals. This feature supports safer operating procedures, particularly when users need to connect or disconnect equipment or proceed to the next testing step after DC power has been switched off.
Specification Comparison
The fanless design, constant-power operation, one-minute online data recording, and built-in protection functions give the OWON SPS programmable DC power supply a clear focus for laboratory and testing applications.
Users should configure the output according to the load requirements, check the rated power limits of the selected model, and follow appropriate safety procedures when connecting and disconnecting the DC power supply.
