## Description

Battery protection panel module, automatically disconnects power when voltage drops below the set threshold and reconnects the consumer at the chosen restart voltage. Compatible with 12-48V, controls loads up to 20A, digital display for monitoring and settings, LED for indicating low voltage status, simple two-button adjustment.
Panel module for power interruption in case of low voltage, settable. Its use is indicated to prevent discharge below a certain battery voltage. When the voltage returns to a preset value, the consumer's supply is resumed. It has an indicator LED for the low voltage state and a display for monitoring the voltage and setting the parameters.
Specifications:
Supply voltage: 12VDC
Battery voltage: 6 - 48VDC
Controlled voltage: 5 - 60VDC
Maximum controlled current: 20A
Voltage error: +-0.1V
Dimensions mm: 78 x 43 x 23mm
Model: YX-20A, YIBAI
Operation:
The 2 buttons adjust the settings. The module enters the setting mode by long pressing one of the buttons until the display flashes.
S1 - Low voltage setting: A short press displays the set value for low voltage. Long press until the flashing display enters the setting mode. The two buttons, up and down, are used to set the desired value.
S2 - Restart voltage setting: A short press displays the set value for the consumer's restart voltage. Long press until the flashing display enters the setting mode. The two buttons, up and down, are used to set the desired value. This setting takes effect when the low voltage event occurred and is used to restart the consumer at the preset value.
The module can come as the YX811 or YX815 version, the difference between them being given by the presence of the internal battery connector (see photo no. 3). The module is powered by the battery.
