Features:

1. 100% brand new and high quality.

2. Delay alarm function: This module will alarm and break the output when the battery is in undervoltage status for 5-20s.

3. Applicable for 12/24/36/48V battery, strong universality.

4. Allowable current through this protection board is 30A  at most.

5. Static power consumption about 12mA (when the battery voltage is normal); Dynamic power consumption about 100mA (battery undervoltage).

 

Specification:

Applicable Battery Voltage: 12/24/36/48V

Load Current: 30A

Weight: Approx. 59g/2.1oz

 

Application Examples:

Example 1: If the load is a motor, the battery voltage will fluctuate when it is started. This protection board can work in this situation, with delay alarm of 5-10 seconds, enough to restore the battery voltage to a stable value.

Example 2: When the car just started, the lights will flash, also because the starting current is relatively large, battery voltage fluctuations, and this protection board can also  work in this situation.

The alarm module is self-locking type: After the battery is in undervoltage status for 5-10 seconds, the module automatically disconnects the output. When the battery voltage rises above the set value, it will not reconnect the load. The module input must be manually disconnected before it can be restarted. You can easily control by connecting a normally closed switch between battery positive pole and module positive pole input end.
