The AIRSYS DC Failover Box is an indoor, wall-mounted power conversion unit that converts 24 VDC or 48 VDC input to 230 VAC output. The unit provides AC pass-through under normal operating conditions when an AC power source is available. Upon loss of AC power, the unit automatically transfers to DC inverter operation, converting DC input power to AC output.
