30kVA static switch, with manual by-pass, 3U 19"rack
Static switch in inverter and UPS applications
An AC/AC UPS system runs mainly on the utility AC in normal operation. The Inverter system is stand-by and operates only at AC failures. The static switch permits a smooth switch over between battery backed up supply and utility supplied AC.
Can be remote controlled to permit selection between on-line or off-line applications. A manual by-pass can also be provided.
