Frequently Asked Questions
Q: What is the XY6020L buck module used for?
A: The XY6020L is a CNC-adjustable DC step-down (buck) power supply module used for a wide range of applications including battery charging, laboratory power testing, LED driver circuits, motor speed control, and DIY electronics projects. It supports both constant voltage (CV) and constant current (CC) modes for versatile use.
Q: Does the XY6020L support remote or automated control?
A: Yes. The XY6020L supports standard MODBUS serial communication protocol, allowing it to be integrated into automated systems, microcontroller setups, or PC-based control environments for remote voltage and current adjustment.
Q: How does the cooling fan work on the XY6020L?
A: The built-in cooling fan activates automatically when the output current exceeds 2A, output power exceeds 50W, or the internal temperature rises above 50°C. It shuts off once current drops below 1.5A, power drops below 45W, and temperature falls below 45°C — ensuring efficient, quiet operation under light loads.
Q: What protections are built into the XY6020L?
A: The module features a comprehensive suite of protections including input/output overvoltage, input undervoltage, overcurrent, overpower, over-temperature, timeout, overcapacity, and over-energy protection — all adjustable to suit your specific application requirements.
