UPS systems are being offered in 3- ,5- and 6-kVA models and are intended to give IT and facility managers N+1 redundancy by connecting two to four UPS systems together. Users unpack the unit and roll it next to the alpha unit. The small footprint allows the paralleling of two, three or four units to achieve 6-kVA, 12-kVA or 18-kVA N+1 redundancy (or increments of 3kVA or 5kVA) without the hassle of buying and populating a full-size rack enclosure.
Falcon Electric Circle 462
Surge protection devices are offered in a variety of application-specific voltages and packaging configurations, the new devices prevent transient voltages from interrupting data streams or damaging vulnerable electronic equipment. Utilizing multi-stage hybrid circuitry based on gas tubes, silicon avalanche components, and reset PTC fuses, the devices address overvoltage transients to provide high-speed, high-energy protection to network signal lines entering or leaving control panels, such as PLCs and universal remote I/O.
