The SPS3010H is an adjustable programmable DC power supply designed for a wide range of applications including product aging, R&D research, education, and manufacturing. This device features a digital display that simultaneously shows voltage, current, and power values, providing comprehensive real-time feedback to the user. Its core function is to provide a stable and adjustable DC power output, with both voltage and current outputs continuously adjustable from 0 up to their respective reference values via an encoder knob.
One of the key usage features of the SPS3010H is its automatic shift mode between constant voltage (CV) and constant current (CC) operation. Both CV and CC values can be conveniently preset using the encoder, simplifying setup for various tasks. The device allows users to activate or deactivate the power supply's output by pressing the OUTPUT push button. When the output is exited, the preset voltage and current values are displayed, offering a quick overview of the configured settings.
For enhanced safety and protection of connected load devices, the SPS3010H incorporates an Over-Current Protection (OCP) function. In the event of a short circuit or over-current condition in the load device, the OCP will activate, causing the power supply to exit output mode and trigger a blinking OCP alarm. The output can be restored by resolving the short circuit and pressing the OUTPUT button. This protective mechanism is crucial for preventing damage to sensitive equipment. The OCP mode can be activated or exited by pressing the "CURRENT" knob for 3 seconds. Users can also adjust the OCP setting by rotating the "CURRENT" knob, with the OCP indicator lighting up and the display showing "0" or "1" to indicate its status. Similarly, an OPN (Over-Voltage Protection) mode can be activated or exited by pressing the "OUTPUT" button for 3 seconds, offering another layer of protection.
The SPS3010H boasts excellent stability and a low ripple coefficient, ensuring clean and reliable power delivery. It also includes comprehensive circuit protections against short-circuit, over-voltage, over-current, and over-temperature conditions, contributing to its robust and safe operation. The device is designed for user-friendly operation, allowing for longer periods of full-load working without compromising performance. An inbuilt USB port provides a convenient charging function, adding to the versatility of the power supply.
The display features a 4-digit readout for setting and actual voltage and current values, providing precise monitoring. To ensure optimal operating temperature, the SPS3010H utilizes a low-noise, thermal-controlled cooling fan. A practical feature is the automatic storage of CV and CC values when the power supply is turned off or shut down. Upon powering on again, the previously stored values are automatically recalled, saving time and effort for repetitive tasks. Display contrast can also be adjusted by simultaneously rotating both "VOLTAGE" and "CURRENT" knobs when the display shows "OFF," allowing users to customize brightness for better visibility.
Connecting a load to the power supply is straightforward: users rotate the terminal knob counterclockwise, insert the load terminal, and then turn the knob clockwise to secure the connection. Banana plugs can also be directly inserted into the terminal hole. It is crucial to ensure proper polarity, especially when charging rechargeable batteries, to prevent damage to the power supply or load devices.
In terms of maintenance features, the product is offered with a free maintenance service for one year from the date of purchase. This warranty covers manufacturing defects but excludes failures caused by improper use, handling, repair, modification, or adjustment of the device. Consumable materials are not covered, nor are damages resulting from natural disasters such as floods, fires, or earthquakes. Repairs exceeding the warranty period will incur costs, which are the responsibility of the user.
For general maintenance, it is recommended to disconnect the power when the product is not in use and unplug the power supply before cleaning. Users should avoid using hydrocarbons, chlorides, similar solvents, or abrasive cleaners for cleaning. Proper grounding of the power cord is essential to prevent leakage current and reduce output ripple interference. If the power socket lacks grounding, the housing case of the power supply should be connected to ground with a wire.
When operating, it's important to use a power cord compliant with the device's rated power and ensure the device is properly grounded to mitigate leakage current from the anti-electromagnetic interference circuit. The device should not be operated in environments with flammable, explosive, or corrosive gases. The ventilation vents must not be blocked, and the power supply should always be operated in a well-ventilated environment. Selecting suitable output wires based on the current value and maintaining tight, clean, and rust-free connections is crucial to prevent damage to terminals, load devices, or potential fire hazards. In case of malfunction, users should consult their local A/S for assistance or return the unit for repair, as high voltage may remain in the circuit even after power-off, and self-repair or modification is not advised. Finally, users must ensure the correct AC input voltage (AC220V±5% or AC110V±5%) is used, as incorrect voltage can damage the device.
Fuse replacement is another maintenance aspect. If the fuse blows, the power supply will cease to function. Users must identify and correct the cause of the blown fuse before replacing it with a fuse of the same specification. For safety, the power must be turned off and the power cord unplugged from the outlet before replacing the fuse.
