Used to calibrate the voltmeter if the displayed voltage doesn't match a multimeter reading. P4 (Time Delay):
Press the Left button once quickly. The screen will flash a voltage value. Use the Left (+) and Right (-) buttons to set your lower voltage threshold.
The board features a segmented layout divided into control power, measurement sensing, and physical relay actuation. Understanding these core interfaces ensures safety during physical deployment. Interface Callouts Xh-m608 Manual
: Connect the XH-M608 between the 48V battery bank and the inverter. Set P1 to 42.0V and P2 to 58.4V. If battery voltage falls below 42.0V or rises above 58.4V, the relay opens, disconnecting the inverter to protect the battery bank.
Relay output (mechanically isolated, allowing it to switch external power sources up to 220VAC). Compatible Batteries: Used to calibrate the voltmeter if the displayed
Connect the load's negative lead directly back to the negative terminal of the battery.
Wait 5 seconds without pressing any buttons. The screen will stop flashing, saving your settings and returning to the live voltage display. Wiring Diagrams Use the Left (+) and Right (-) buttons
To make the most out of your device, explore the various customization options:
Use this architecture when you want to terminate an incoming charging current (such as from an AC-to-DC wall charger, solar charge controller, or wind turbine) once the battery hits its maximum capacity ceiling.
The board features a three-digit LED display, two control buttons (, + , and - ), and a heavy-duty relay.
For a 12V battery, you might set P1 to 10.8V and P2 to 14.4V to automate the charging cycle. P3: Timer Function Set this to 0 to disable the timer.
