The KUAIQU KQ3010R-4KD is a 4 channel programmable DC power supply built for electronics R&D, laboratory testing and production verification. BDTronics provides this multi channel bench power supply for engineers, technicians, students and testing teams who need to power several circuits, modules or boards at the same time from a single instrument. Each of the four outputs is independently adjustable and rated at 30V and 10A, so separate voltage and current settings can be applied to different devices during the same test session.

Features:

• Four independent adjustable DC outputs rated 30V and 10A per channel
• Real-time LED display of voltage, current and power for all four channels simultaneously
• High precision and high resolution adjustment for stable, low ripple DC output
• Programmable remote control through USB, RS232 and RS485 communication interfaces
• Individual Over Voltage Protection (OVP) and Over Current Protection (OCP) on every output channel
• 3 groups of memory storage per channel for saving and recalling frequently used voltage and current settings
• Independent output ON/OFF switch on each channel for flexible and safer operation
• USB-A and USB-C charging ports for powering USB devices and development boards
• Intelligent temperature controlled fan that adjusts speed according to internal temperature, reducing noise during operation
• Series has passed CE and FCC certification

For engineers comparing bench instruments, the KQ-4KD series from BDTronics combines a precision programmable power supply with the multi-device capability usually handled by several separate single-output units. The programmable control interfaces make the unit suitable for automated test benches, laboratory experiments and repeated production checks where settings must be recalled quickly.

Specifications:

Specifications listed above are taken from the KQ-4KD series datasheet; the KQ3010R-4KD variant is rated 30V and 10A per channel.

Applications:

• Electronics R&D: prototype development, PCB testing, circuit debugging and hardware verification
• Laboratory testing: electronic experiments, engineering education and precision measurements
• Production testing and quality control: product inspection, functional testing and aging tests
• Automated test systems: PC controlled testing, system integration and production automation
• Embedded system development: powering and testing MCU boards, sensors and communication modules
• Multi-device testing: simultaneous testing of several circuits, modules and electronic components
• Communication and industrial electronics: stable power for control systems, electronic equipment and measurement devices

How to Use:

1. Confirm that the input voltage version of the unit matches your mains supply before connecting power.
2. Connect the supplied input cable to the mains and switch the instrument on.
3. Use the front panel controls to set the required voltage and current for each of the four channels.
4. Connect your load to the output terminals using the supplied output cable.
5. Enable or disable each channel individually with its own output ON/OFF switch.
6. Store frequently used voltage and current values in one of the three memory groups available per channel for quick recall.
7. For remote or automated testing, connect the unit to a PC through USB, RS232 or RS485 and control the outputs from your test software.

Installation and Wiring:

Place the power supply on a stable, well ventilated surface and keep the rear and side ventilation paths clear so the temperature controlled fan can move air freely. Use the supplied input cable for the mains connection and respect the fuse rating that matches your input voltage. Route output cables from the front terminals to the device under test, keeping the leads as short as practical to reduce voltage drop and noise pickup. When more than one channel is used at the same time, connect each circuit to its own channel so that OVP and OCP protection acts on that specific output.

Compatibility:

• Available in AC110V (±10%) and AC220V (±10%) input versions
• PC based control and automated testing platforms through USB, RS232 and RS485 interfaces
• Suitable for powering development boards, sensors, communication modules, control circuits and other low voltage DC loads within the 30V / 10A per channel rating
• USB-A and USB-C ports for powering USB accessories and development boards

Safety Information:

• Use only the input voltage version that matches your mains supply; do not exceed the rated 30V / 10A per channel output.
• Replace the fuse only with the specified rating: 10A for 230V input and 20A for 115V input.
• Keep the unit dry and away from liquids, and do not block the cooling vents during operation.
• Rely on the per-channel OVP and OCP protection to limit abnormal voltage or current conditions, but always verify settings before connecting sensitive devices.
• Disconnect the mains supply before cleaning, inspection or moving the instrument.
