Dear Friend,

Please contact Ms.Linda for price, catalog, user manual and service.

STS STS static transfer switches are available in singlephase double-pole 16A,32A and 50A versions. STS ensures maximum reliability to critical loads by eliminating system failures caused by problems in distribution rather than by the failure of the power source itself. Double-pole operations ensure optimal flexibility for all the different types of electrical distributions.

STS Three phaseSTATIC TRANSFER SWITCHThe Hairf Static Transfer Switch is a solid state three phase STS designed to connect a critical loads to one of two separate sources of power, to assure supply continuity. The source to which the load is normally connected is designated as priority source and other as alternative source.Hairf STS is fitted with two internal maintenance by-pass switches, which enable a load transfer to the supply sources without causing a power interruption to the critical load. Bypass isolation is complete, allowing all serviceable components to be maintained in safety.

Hairf switches between different AC inputs lines according to priority criteria and technical characteristics of the input voltages. If the lines are synchronized, the transfer time from one source to the other is less than 4 ms.

A clever key-operating interlocks ensures that the two bypass switches (one for each line) cannot be simultaneously closed, thus avoiding the direct connection of the two sources. The control logic ensures that in the event of an accidental closure of the bypass on the passive line, the Hairf STS will automatically transfer the load on the line should the bypass operation has been carried on. The layout is designed for maintenance and service for the active components from the front.STANDARD OPTIONS:3-phase 4-pole configuration plug-in circuit breakers operation without neutralOPTION ON REQUEST:
