Description
Features
- Manual-Auto Flexibility: Our voltage sensitive relay allows you to choose the mode that best suits the scenario, ensuring a more flexible battery system.
- Zero Voltage Drop: Thanks to the optional Storage Mode of our dual battery isolator, you can experience zero power consumption when your engine is off.
- Stable Voltage Control: The voltage-sensitive chip maintains a stable voltage connection at 13.3V, disengaging below 12.8V for a consistently charged main battery.
- Dual Sensing Technology: With the technology, our VSR monitors the voltage of both batteries, allowing the transfer of excess charge from the auxiliary to your starter.
- Battery Protection: The voltage sensitive relay safeguards your battery against over-discharge and shield sensitive equipment from damaging power surges.
- Weather & Dust Proof: With an IP67 rating for its silicone-sealed interior, our VSR thrives in challenging environments, ensuring a smooth and pleasant journey.
- LED Status Indicator: With the built-in LED indicator in our battery isolator, you can easily assess whether your system is connected or disconnected at a glance.
- Broad Compatibility: Compact and suitable for various applications, this device is perfect for ATVs, UTVs, RVs, marine applications, trucks, and caravans.
- Effortless Installation: Our voltage-sensitive relay includes the necessary hardware, mounting instructions and even a 6-meter cable for a more flexible installation.
