Features:
1. Support firmware upgrading, support MPPT solar charging, support serial communication, standard MODBUS agreement
2. Visualization range of 38 * 29mm, LCD screen layout is reasonable, full and rounded fonts, professional power supply LCD screen, you want the function it has!
3. Adopt one-piece injection molding shell, flame retardant material is safer! Double-layer buckle design, double circuit board fixed more firmly; display board using immersed gold design, anti-oxidation, better conductivity and more durable!
4. High-precision external clock crystal, to ensure the accuracy of the time, capacity/energy statistics more accurate, 48-pin powerful MCU controller, 64M frequency computing speed faster!
5. Upgraded PCB welded terminals (M3), greater current, lower heat, more reliable

Precautions:
1. Input can not be connected to AC power, not to mention 220V utility.
2. The maximum input voltage can not exceed 145V, it is recommended to use within 140V, positive and negative poles can not be connected to the reverse.
3. The output is not anti-reverse irrigation, 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 series diode single conduction, to prevent the battery voltage reversal burns the power supply.
4. This product has no output reverse connection protection, the battery positive and negative poles will be reversed to damage the equipment. Battery charging requires a certain degree of expertise, non-professionals please do not charge directly to prevent fire and explosion.
5. The product is a step-down power supply, maximum output voltage = input voltage * 0.945.

Package include:
Package A: adjustable power supply *1 + meter *1 + cable *2
Package B: adjustable power supply *1 (base plate can be used independently)
