This series of products is a single-channel DC regulated power supply with 4-bit LED digital display; Automatic switching between constant voltage (CV) and constant current (CC) modes; The output voltage and current limiting current are continuously adjustable; Advanced switching power supply control technology and components are adopted, which has high efficiency, light weight, energy saving and environmental protection, and can provide 5V2A USB fast charging function (optional).
Features:
Display Mode: LED digital display, 4-digit digital voltage, current and power display.
Multiple Protection: over-voltage, over-current, over-power and over-temperature protection
Efficient Heat Dissipation: With fan vent and intelligent temperature control fan, used for internal heat dissipation of power supply, intelligent temperature control adjustment, energy saving and electricity saving.
Data Storage and Recall: 3 sets of shortcut parameter storagerecall functions, which are convenient and effective.
Easy to Use: Constant voltage (CV) and constant current (CC) modes can be automatically switched, with status indicator. Encoder adjustment, the specified number of digits can be adjusted accurately.
Support a Variety of Communication Modes: The product provides users with up to three communication modes, namely USB(optional), RS232(optional) and RS485(optional), to realize remote control.
