KORAD KD Series Programmable DC Power Supplies
Manufacturer: SHENZHEN KORAD TECHNOLOGY CO., LTD.
Website: www.koradtechnology.com, www.korad.com.cn
Product Overview
The KORAD KD3000/6000 series comprises digital control and programmable DC power supplies, featuring encoder-controlled operation and LED displays. These power supplies are equipped with standard interfaces, including USB and RS232, facilitating convenient and rapid remote communication. The series offers two distinct adjustment modes for the encoders, catering to various user operational preferences. The KD series includes up to 10 different models, with power ranges spanning from 90W to 300W.
Product Description (Front Panel): The front panel features a prominent digital display showing Voltage (e.g., 30.00V) and Current (e.g., 0.000A). Indicator lights display the status of Over-current Protection (OCP), Constant Current (C.C), Constant Voltage (C.V), and a panel lock function ([Lock Indicator]). The unit has a Voltage Adjustment Knob (Digital Encoder) with functions for Push/Hold and LOCK/UNLOCK, and a Current Adjustment Knob (Digital Encoder) with functions for Push/Hold and OCP ON/OFF, along with FINE/COARSE adjustment. A Power Switch is also present. Output terminals and an Earth (Ground) Terminal are located on the front panel.
Product Description (Rear Panel - KD..P Version): The rear panel includes a Fan Vent for cooling, an interface for USB with Photoelectric Isolation, and an interface for RS232 with Photoelectric Isolation. It also features a label indicating voltage and fuse rating, and an AC Power Socket.
Product Description (Rear Panel - KD..D Version): Similar to the KD..P version, the KD..D version has a Fan Vent, a label on Voltage and Fuse, and an AC Power Socket. It also includes interfaces for USB and RS232 with Photoelectric Isolation.
Software Testing Interface: A graphical user interface is available for software testing, which mirrors the power supply's operational display and controls, allowing for remote monitoring and management.
