KG-175 Failover Adapter

The CS FO175 has been designed and developed specifically to meet the needs of users who require a high reliability power supply solution for the KG-175 family of HAIPE devices. Customers who implement the CS FO175 will have peace of mind knowing that their KG-175 A, B, D or G HAIPE device will remain powered and online in the event of a power supply failure. The CS FO175 uses two power supplies in a failover arrangement so if one of the two power supplies fails, the KG-175 device will remain powered by the second power supply. It does this instantaneously and automatically with no user interaction. The CS FO175 utilizes either the KG-175 OEM power supply or the highly reliable power supplies that we produce specifically for the KG-175 family and works with either the KG-175A, B, D, and G HAIPE devices.
