XY7025 DC Buck Converter CNC Step-down Adjustable Regulated Laboratory Power Supply Constant Voltage Current Solar Charge Module

Features:
1. The product adopts silicone buttons, comfortable hand feeling, each button with cool indicator light
2. LCD screen layout is reasonable, the font is large and full of rounded, professional power supply LCD screen, you want the function it has!
3. Adopting one-piece injection molding shell, flame retardant material is safer! Double-layer buckle design, double-layer circuit board fixed more firmly
4. The product supports serial communication standard Modbus protocol, support for firmware upgrade, support for MPPT solar charging, comprehensive functions.
5. Upgrade PCB welded terminals (M3) current is greater, lower heat, more reliable!
6. The product has a wide range of applications, there is a backflow prevention function can be charged to a variety of rechargeable batteries, and with MPPT function to support MPPT solar charging, can be connected to the external temperature probe to support over-temperature protection and so on.

Precautions:
1. Input can not be connected to AC power, not to mention 220V utility power
2. The maximum input voltage can not exceed 90V, it is recommended to use within 85V, positive and negative poles can not be reversed.
3. The output is not anti-backup, when connecting the battery to ensure that the power supply output voltage is always higher than the battery voltage, or in the power supply output positive diode series single conduction, to prevent the battery voltage back-up burns the power supply
4. When connecting the battery to the output terminal, please pay attention to the positive and negative poles not to be reversed.
5. The product is a step-down power supply, the maximum output voltage = input voltage * 0.945
