High precision with 1mV/1mA resolution
Low ripple and noise (<1mVrms)
Constant Voltage (CV) and Constant Current (CC) modes
4-digit LED display for real-time monitoring
Overvoltage, overcurrent, and short circuit protection
Temperature-controlled cooling fan
Memory recall and output on/off control
USB and RS232 communication interfaces
Compact, rack-mountable metal chassis

The PPH-1510D High Precision Dual Channel Output DC Power Supply is a professional-grade power solution engineered for electronics laboratories, R&D environments, and testing facilities requiring stable and precise DC output. It features two fully isolated output channels, each capable of supplying up to 15V and 10A, allowing both independent or synchronized operation for greater flexibility. The unit delivers exceptionally low ripple (<1mVrms) and high resolution (1mV/1mA), ensuring clean, noise-free power suitable for delicate analog circuits and digital systems. Equipped with a bright 4-digit LED display, users can easily monitor voltage and current in real-time with high accuracy. The power supply supports constant voltage (CV) and constant current (CC) modes, with automatic crossover and fine adjustment knobs for precise control. It incorporates comprehensive safety mechanisms, including overvoltage protection (OVP), overcurrent protection (OCP), short circuit protection, and temperature-controlled fan cooling to ensure long-term reliability and device safety. The compact 2U rack-mountable design with a rugged metal chassis makes it suitable for both bench-top and system integration use, while built-in memory recall functions, remote control capability via USB/RS232 interface, and output on/off control further enhance its usability and efficiency in a wide range of applications.
