Thiết bị chuyển mạch STS
iSTS Model W 32A to 100A
The Model W is a wall-mount unit for use at the point of distribution where the STS is close to the load. It has an excellent power rating to size ratio, ideal for high-current small-space installation. The design incorporates an integrated maintenance bypass. Comes standard a decal and graphic OLED with the option of a colour touch screen LCD interface.
iSTS Model B4w 63A to 160A
The Model B4 is a high-power capacity static transfer switch with a hot-socket field replaceable power module. This model is ideal for high power installations with the convenience of wall mounting. Perfectly adapted to large power surge or motor and transformer start up.
iSTS Model C 63A to 160A
Generally dedicated to a single sensitive application where power continuity is critical. iSTS model C rugged design is adapted to all industrial environments.
Compact, wall mounted, iSTS Model C frees floor space.
iSTS Model K 250A to 630A
The iSTS Model K feeds a single level of distribution or are used in pairs to improve availability in dual corded distribution systems.
Ideally suited for corridors and computer rooms with just 400mm in depth.
iSTS Model Hw 100A to 250A
The Wall-Mount Solution for Decentralised Distribution iSTS Model Hw provides protection against infrastructure failures and upstream inadvertent switching events. It is a rugged fuse-less design capable of reliable operation under the most arduous operating conditions.
Wall mounted and with just 300mm depth, iSTS Model Hw is suited for limited spaces.
iSTS Model H 100A to 250A
The iSTS Model H provides protection against infrastructure failures and upstream inadvertent switching events. It is a rugged fuse-less design capable of reliable operation under the most arduous operating conditions. With just 300mm depth, iSTS Model H is suited for limited spaces.
GE's STS Series 25-1000A
230V/3x400V 25-1000A 2/3/4-pole Static Transfer Switches (STS)
Static Transfer Switches (STS) are designed to transfer the supply between two independent AC power sources. Unlike traditional automatic transfer switches (ATS), a static transfer switch provides a fast load transfer (typically 1/4 of a cycle), which ensures uninterrupted operation of sensitive electronic equipment. Load retransfer to the preferred input source is virtually instantaneous (typically 0.1 ms).
The basic applications of STS are in automatic systems in the power industry, power supply systems for petrochemical industry, computer and telecommunication centres, automatic and security systems of ‘intelligent’ buildings as well as other equipment which is sensitive to interruptions in the supply.
STS-3 Series, Three Phase
GE Critical Power is a supplier of static transfer switches to a wide range of industries. The GE Zenith STS-3 Series static transfer switch supplies critical loads with a choice between two available sources of electrical power. By continually monitoring power quality, the STS-3 switch automatically transfers to an alternate source without interruption of power to even your most sensitive critical loads. With a sense and transfer time of less than 4ms, and the industry’s best communication package, the STS-3 represents the highest performance power switching solution available.
