Description:
- Name:Battery Charger Discharger Board & Undervoltage Overvoltage Protection Timing Charge and Discharge with Communication Function
Module highlights:
- 1. battery charging and discharging control, automatic power failure after setting.
- 2. can set charge and discharge time;
- 3. with serial communication function, the working state of the relay can be monitored in real time through the serial port.
- 4. extra signal output, which can control other devices when meeting the relay's conduction condition and output high level.
- 5., there is one button emergency stop function (STOP key), with reverse connection protection, reverse connection without burning.
Work model:
- The upper voltage limit is UL1, the voltage limit is nL1, the voltage limit is greater than the voltage limit (UL1>nL1).
- U-1: charging measurement: when the measuring voltage is lower than the lower limit voltage, the relay will pull in and exceed the upper limit voltage, and the relay will be disconnected.
- U-2: charge measurement time control: set charge time (OP); when the measurement voltage is lower than the lower limit voltage, the relay suck in, after suction starts to countdown OP time, the time is up, the relay is disconnected, the relay is higher than the upper limit voltage, the relay is disconnected.
- U-3: discharge detection: when the measuring voltage is lower than the lower limit voltage, the relay is disconnected, higher than the upper limit voltage, and the relay is absorbed.
- U-4: discharge detection time control: set discharge time (OP); when the measurement voltage is higher than the upper limit voltage, the relay suck in, after absorption, it starts to countdown OP time. When the time comes, the relay is disconnected; when the measurement voltage is lower than the lower limit voltage, the relay is disconnected.
- U-5: pull in the interval: when the measuring voltage is between the upper and lower limits, the relay will pull in and the rest will be disconnected.
- Outside the U-6: interval suction: when the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay will pull in, and the relay will be disconnected in other cases.
Specification:
- Size:5x2.8cm/1.96x1.10 inch
Package Includes:
1 Piece Battery Charger Discharger Board
Let customers speak for us
from 614 reviewsExtremely Disappointed – Terrible Service, No Delivery After 1 Month!
Review:
I am beyond frustrated with this shopping site. I placed an order over a month ago, and I have yet to receive the product. The lack of communication and failure to fulfill the order is completely unacceptable. I have sent multiple inquiries with no proper response. This is the worst shopping experience I have ever had.
I strongly advise others to avoid this site, as they clearly cannot handle basic customer service or delivery. If you value your time and money, do not waste either here.
This company has absolutely no regard for its customers. I expect a full refund, or I will be forced to take legal action. Do yourself a favor and shop elsewhere.
