KUAIQU SPPS-K3010R-4KD 30V 10A 300W 4-Channel DC Power Supply 

Product Overview

The KUAIQU SPPS-K3010R-4KD is a professional 30V 10A 300W 4-channel DC power supply designed for battery testing, battery charging, battery pack evaluation, DC motor testing, automotive electrical systems, and high-current electronics. Each independent channel provides 0–30V and 0–10A adjustable output, delivering up to 300W per channel for power-intensive low-voltage applications.

Its modular 4U pull-out chassis allows individual power supply units to be removed and used as standalone DC power supplies, providing flexible configurations for multi-channel testing or separate workstations. With four independent outputs, precise CV/CC regulation, low ripple and noise, OVP/OCP protection, preset storage, and USB/RS232/RS485 communication, the SPPS-K3010 is designed for demanding high-current multi-channel testing.

Key Features

• 30V 10A 300W Per Channel: Each channel provides 0–30V/0–10A adjustable output with up to 300W power, making this 30V 10A 300W 4-channel DC power supply suitable for higher-current low-voltage applications.
• Modular 4U Pull-Out Design: Individual power supply units can be pulled out and removed from the 4U modular chassis for standalone operation, allowing users to switch between centralized four-channel testing and independent bench testing.
• 4 Independent High-Current Outputs: Four channels can operate independently, allowing multiple high-current devices, battery packs, motors, or electronic circuits to be powered simultaneously.
• Independent Output ON/OFF Control: Each channel has a dedicated switch, allowing individual loads to be connected or disconnected without affecting the remaining channels.
• Simultaneous Voltage, Current & Power Monitoring: The LED display provides real-time voltage, current, and power information across all four channels for convenient load monitoring.
• Stable CV/CC Regulation: Continuous voltage and current adjustment with automatic CV/CC conversion provides controlled output for battery and high-current electronics testing.
• Low Ripple & Low Noise: Clean and stable DC output supports reliable testing of battery systems, motors, power modules, and electronic assemblies.
• OVP & OCP Protection: Each channel includes independent Over Voltage Protection and Over Current Protection to help protect the connected equipment and power supply.
• 3 Groups of Preset Data: Three sets of voltage and current settings can be stored and quickly recalled for repetitive battery testing and production testing.
• USB / RS232 / RS485 Communication: Supports external control and integration with automated test equipment and laboratory systems.
• USB-A & USB-C Charging: Built-in USB-A and USB-C ports provide auxiliary charging for compatible electronic devices and test accessories.
• Intelligent Temperature Control: The temperature-controlled fan adjusts automatically according to internal temperature, helping maintain stable operation and reduce unnecessary noise.
