Static Bypass Switches

Static Bypass Switch STS207

The new STS207 is a series of very compact Static bypass switches. Minimized synchronization time of inverter and mains frequency is guaranteed by digital PLL. The transfer time between both inputs is less than 4msec. Therefore the STS207 can be used with equipment very sensible to small dips in the AC supply.

Product Description

The STS monitors both incoming sources according to the voltage level, frequency and their synchronization. In combination with the inverter series INV215/INV222 the unit can operate in Offl ine or Online-mode. This function is programmable at site. All main functional parameters and measuring values are displayed on the front side LCD panel. For highest reliability the internal circuits are supplied in redundancy by the bypass mains as well as the battery circuit of the AC system. For communication between STS and inverter a CAN bus communication is used. The unit is equipped with an ethernet interface for remote connection via SNMP-Protocol or WEB-Browser.

Key Features

• 1/4x19", 2U
• "Hot-Plug-In" design with backplane connection
• Optimized synchronization speed with digital PLL
• CAN-Bus interface
• Display for all main operating parameters settings and measuring values
• Front- to- rear airfl ow with temperature-controlled fan cooling
• SNMP interface and monitoring by WEB-Browser included

Static Bypass Switch UNB5.0

The UNB range of static bypass switches features the modern micro controller technology for monitoring, synchronization and communication combined with a fl exible 19"-compatible rack mounting.

Product Description

These modular units are designed for systems consisting of inverters type UNV or PWS. Parallel connection up to 5.0kVA is possible to increase output power or system reliability by (n+1)-redundancy. The micro processor-controlled synchronization unit guarantees mains synchronicity of single or paralleled inverters. The availability of all inverters in the system is continuously checked and monitored. All monitoring functions and system parameters are indicated and adjusted comfortably by an alphanumeric display and control keys on the front panel. All system parameters can be read out together with the central monitoring unit UPC3 (optionally).

Key Features

• 19", 3U
• "Hot-Plug-In" design, rear side connection
• Wide synchronization range
• Optimized mains synchronization
• Alphanumeric LCD display for measurement values and systems parameters
• Complete system monitoring via CAN bus
• Temperature-controlled fan cooling
