Still confused about our DC regulated power supplies after checking the FAQs? Please contact our customer service, we are ready to solve all your problems.

Use overlay text to give your customers insight into your brand. Select image and text that relates to your style and story.

Our customer service can walk you through all settings. You can also watch full operation tutorials on our YouTube channel, including OVP, OCP, memory storage function and other operation guides. Our official blog also has lots of technical articles for reference.

Partial KUAIQU power supplies support program control with USB, RS232, RS485 interfaces, based on Modbus protocol. Remote control can be realized via our self-developed PC software. If you need this function and confirm interface configuration of a model, email us: kuaiquinstrument@163.com..

The banana plug adopts cross-slot design. Pry the metal slot slightly open with a screwdriver to make the plug clamp terminals tighter and safer..

All KUAIQU DC power supplies support basic battery charging. For dedicated long-term charging, our patented battery-charging model with independent BATTERY key and full charging protection is highly recommended.

A certain amount of ripple is normal for all switching DC power supplies. Ripple is a small residual AC component superimposed on the DC output and is an inherent characteristic of switching power supply technology. The typical ripple voltage of our power supplies ranges from approximately 100 mV to 300 mV, which is suitable for most general-purpose testing, maintenance, and electronic applications.

A: Minor fluctuations in the last displayed digit are normal and are typically caused by temperature drift within the electronic components. As ambient and internal temperatures change, small variations in the readings may occur. This falls within normal industry tolerances and does not affect the power supply's suitability for everyday electronics work, home repairs, DIY projects, or general testing. For applications requiring extremely high precision and ultra-stable output, a linear DC regulated power supply may be more appropriate.

This is normal and does not indicate a malfunction. The internal capacitors continue to hold a small amount of stored energy after the power is switched off. As the capacitors discharge, the display will gradually turn off, typically within 5–8 seconds.

In CV mode, the power supply maintains a fixed output voltage while the current varies according to the load. In CC mode, the power supply limits the output current to a preset value, automatically reducing voltage if necessary. CC mode is especially useful for battery charging, LED testing, and protecting electronic components.

This is normal behavior. The power supply contains internal filter capacitors that store electrical energy. When the output voltage is reduced, these capacitors require a few seconds to discharge, causing the displayed voltage to decrease more gradually than when increasing the voltage. Q: Why does t

If you have any other questions or technical doubts about our DC power supplies, please feel free to contact us anytime. Our professional support team will reply to you as soon as possible.

Output ripple refers to small residual AC fluctuations present in the DC output. Lower ripple levels provide cleaner power, which is important when testing sensitive electronics, RF circuits, audio equipment, and precision instruments.

Yes, all DC regulated power supplies manufactured by KUAIQU support battery charging. However, if you mainly intend to charge batteries, I would highly recommend our patented DC power supply specially designed for battery charging. It comes with an exclusive dedicated BATTERY function key, and built-in specialized charging protection functions to safeguard your batteries during the whole charging process..

This is normal behavior. The power supply contains internal filter capacitors that store electrical energy. When the output voltage is reduced, these capacitors require a few seconds to discharge, causing the displayed voltage to decrease more gradually than when increasing the voltage..

This is normal and does not indicate a malfunction. The internal capacitors continue to hold a small amount of stored energy after the power is switched off. As the capacitors discharge, the display will gradually turn off, typically within 5–8 seconds..

This is a common operation issue for adjustable DC power supplies. Please follow the steps below to solve the voltage adjustment failure: Turn the current adjustment knob clockwise moderately to set the unit to constant voltage (C.V) mode; After confirming the power supply enters CV mode, turn the voltage adjustment knob clockwise, then you can freely adjust the output voltage value..

It is recommended to pre-adjust the voltage to around 5V before operation. This step prevents spark generation when connecting short-circuited loads, which effectively avoids safety accidents and other hidden electrical hazards..

A: Our banana plug adopts cross-slot design. If the plug becomes loose, use a screwdriver to slightly pry open the metal slot, which can make the plug clamp tighter and connect more safely..

Some models of our KUAIQU DC regulated power supplies support programmable control. They are equipped with USB, RS232 or RS485 communication interfaces and adopt the Modbus protocol. You can realize remote control easily by using our self-developed PC software. If you need programmable control but are unsure whether a specific model comes with your required communication interface, please feel free to contact us via email: kuaiquinstrument@163.com.

If you have any confusion about using OVP, OCP and other built-in functions, our professional customer support staff will provide targeted guidance for you. We also upload complete step-by-step tutorial videos on our official YouTube channel. Apart from OVP and OCP over-protection setup, the videos demonstrate memory storage function and all common operation skills. You can visit our channel via https://www.youtube.com/ In addition, our official blog contains a large number of popular science and technical articles about DC power supplies, you can search and browse related content to solve your problems.
