THREE PHASE ELECTROMECHANICAL LINE CONDITIONERS STI range

The three phase line conditioners of the STI range add the the usual characteristic of ST range the high protection of a three phase isolation transormer, which galvanically separates thee loads from the network and provides harmonic attenuation and protection of all loads. STI range can be also used where a neutral is not available, or in the areas where a 220V three phase without neutral is available, simply requiring a 220V (230V) input stabiliser, giving a 400V+N stabilised output voltage. STI range is fitted with input automatic circuit breaker, digital voltmeter with input/output voltage reading switch, fine output stabilised voltage regulaiton
