The KUAIQU KQ-4KD Series is a 30V 4-channel programmable DC power supply designed for electronic engineering, hardware development, and professional circuit testing. Available in 5A and 10A models, this multi-channel DC power supply features four independently controlled output channels for powering, adjusting, and monitoring multiple electronic circuits simultaneously. With programmable remote control, real-time voltage, current, and power monitoring, individual channel protection, and preset memory functions, this four-channel bench power supply supports electronic circuit design, PCB testing, hardware debugging, prototype development, and engineering verification. It is a versatile multi-output DC power supply for engineers, electronics developers, and R&D teams.
The KQ-4KD Series combines four independent adjustable outputs in one programmable DC power supply. Engineers can power different circuit boards, electronic modules, and hardware components within the same test setup. This 4-channel power supply helps simplify bench arrangements and provides flexible power management for electronic engineering projects, circuit development, and multi-module testing.
Available in 30V 5A and 30V 10A configurations, this multi-output DC power supply accommodates different current requirements in electronic engineering applications. The 5A model is suitable for general circuit development and electronic module testing, while the 10A model offers a higher-current option for compatible power circuits and electronic loads. This range gives hardware engineers greater flexibility when selecting a four-channel power supply for their projects.
Monitor voltage, current, and power readings for the output channels through the integrated LED display. This multi-channel bench power supply helps engineers observe electrical behavior, compare circuit operating conditions, and identify irregularities during PCB debugging, electronic module testing, and prototype verification.
USB, RS232, and RS485 communication interfaces support integration with compatible computer-controlled systems. Engineers can incorporate this programmable multi-channel power supply into automated testing workflows, development benches, and customized electronic test platforms. Remote control is particularly useful for repeated measurements, engineering verification, and testing procedures that require consistent output settings.
Each output channel incorporates over-voltage protection (OVP) and over-current protection (OCP). These functions help protect connected electronic circuits and modules against abnormal output conditions. Independent channel protection makes this four-output DC power supply a practical choice for hardware development, circuit debugging, and multi-module testing.
Each channel supports three groups of stored parameter settings for convenient recall of frequently used voltage and current values. Engineers can switch between saved settings when testing different circuit configurations, reducing repetitive manual adjustments and helping maintain consistency across recurring engineering procedures.
Individual channel ON/OFF switches allow engineers to enable or disable specific outputs as required. This function is useful when isolating circuit modules, changing test configurations, and evaluating different sections of an electronic system without unnecessarily interrupting other active outputs.
The KQ-4KD Series supports fine adjustment of output voltage and current, making it suitable for controlled circuit evaluation and electronic hardware development. Its specified adjustment resolution allows engineers to set experimental conditions and monitor changes during circuit characterization, prototype testing, and engineering verification.
The built-in temperature-controlled fan adjusts its speed according to internal temperature. This cooling system helps manage heat during operation while reducing unnecessary fan noise when cooling demand is lower, supporting a more comfortable electronic engineering workstation.
USB-A and USB-C auxiliary power ports provide convenient power for compatible development boards, USB-powered devices, and electronic accessories. These additional connections help simplify workbench arrangements during electronic prototyping and hardware integration.
