Description

This line of products features a single-channel DC regulated power supply with a 4-digit LED digital display. The devices automatically switch between constant voltage (CV) and constant current (CC) modes. The output voltage and current limiting currents are continuously adjustable. Built with advanced switching power supply control technology and materials, these devices offer high efficiency, a lightweight build, energy conservation, environmental friendliness, and a 5V/2A USB fast charging function (optional).

Features

• Display Mode: The device features an LED digital display, capable of showing a 4-digit digital voltage, current, and power display.
• Multiple Protection: Users are protected against over-voltage, over-current, over-power, and over-temperature conditions.
• Efficient Heat Dissipation: The device comes equipped with a fan vent and intelligent temperature control fan for internal heat dissipation, enabling intelligent temperature control adjustment, energy saving, and electricity saving.
• Data Storage and Recall: For convenience, the device includes 3 sets of shortcut parameter storage/recall functions.
• Ease of Use: Users can automatically switch between Constant Voltage (CV) and Constant Current (CC) modes, guided by a status indicator. Encoder adjustment allows for precise digit adjustment.
• Variety of Communication Modes: This product provides users with up to three communication modes, namely USB(optional), RS232(optional), and RS485(optional), to facilitate remote control.
