Pololu Reverse Voltage Protector, 4-75V, 8A
This module protects a connected load from reverse voltages down to -75 V (80 V absolute max). This version does not block reverse current, making it suitable for applications such as battery-powered motor control where delivering energy back into the supply is desirable.
| Operating voltage1 | Max current | Resistance2 | Reverse current blocking | Size |
