OutBack Power FireRaptor OBFRS-ESW1 Shut-off Switch

SKU: 580-0149


OutBack, IMO FireRaptor, Shutdown Switch, OBFRS-ESW1

The IMO FireRaptor module-level rapid shutdown system is a dependable, secure, and straightforward platform.

Each module contains a single FireRaptor OBFRS-01 assembly that is controlled by a two-conductor cable system with its own connectors. There are no wireless or power line communications on this system that could be disrupted by interference from the charge control, inverter, or the environment. The procedure is simple: the units will turn on if they are supplied with 24 VDC fuel; if that power is interrupted, they will turn off. The OBFRS-01 will switch off if the ambient temperature rises above 185°F (85°C), then turn back on when the temperature drops. If the temperature rises above 198°F (92°C), it will shut down and require a manual reset.

This system is compatible with any charge controller or inverter. Two MC4 module connectors on 5-inch pigtails, two string series pigtails with MC4 connectors every 71 inches, and two control wire pigtails with special connectors every 71 inches are included in each OBFRS-01 unit. The control wire is a dual-conductor jacketed wire with interchangeable connectors.

The OBFRS-ESW1 is a solar array emergency shutoff switch that switches on and off. It comes with a power supply that can power up to 40 FireRaptors and converts 120 VAC to 24 VDC. If the machine's 120 VAC power is switched off, the system will shut down automatically. If the manual button is pressed, the unit will shut down. A 48 VDC to 24 VDC power supply can be used instead of the AC to DC power supply that comes with the ESW1 for more reliable manual shutdown for systems with backup power. Emergency shutoff switches from other systems may be used in place of the ESW1. For OutBack, this could be the RSI, and for MidNite, it could be the MNBirdhouse. Similar to the ESW1, the Aux link closure in those switches would cut off power to the FireRators during a rapid shutdown. This is useful for systems with charge controls that involve a disconnect at the charge control end of the circuit because the FireRaptor system does not directly serve that function.
