The RIPEnergy Gateway RY-uni-directional relays can be programmed to behave as Voltage SensitiveRelays (VSR) or Low Voltage Disconnects (LVD) and are designed to monitor source (battery) voltage while providing current to a load (accessory) as long as the battery voltage stays above a particular preset level. An integrated microcontroller is factory programmed to cause the device to open or close by constantly monitoring battery voltage, load current, internal temperature, and timing cues. It is truly a Perfect Switch capable of responding exactly how the user requires, all in a single highcurrent module capable of handling all high-current andlow-current accessories. The arrayed MOSFET SSR is designed to switch and control DC currents up to 100A.
