Static Transfer Switch - 60 Hz
The solid-state bus transfer switch is the enabling technology behind dual-bus power systems. These devices are connected between your critical load and the outputs of two independent UPS systems. If the primary UPS should fail, the switch will automatically transfer the loads to the surviving UPS. The STS 2 has triple-redundant logic. Each DSP controller is capable of working independently, and each helps monitor the other two. If one malfunctions, the other two lock it out. Each controller has power feeds from both power supplies. Available in 100 to 1000 Amps
Features
- Complete Front-Access
- Color Touchscreen Monitor
- Triple-Redundant, Self-Correcting Logic
- Internal Dual-Bus Control Power
- Simplified Installation & Maintenance

SmartSwitch - 60 Hz
If your critical electronic equipment demands the reliability of redundant power
sources, the SmartSwitch provides rapid switching between two independent AC power
sources, for uninterrupted operation of critical electronic equipment. It automatically
transfers from the failing power source to the alternate source immediately upon
detection of a problem — in less than six milliseconds. SmartSwitch's proven
power switching technology allows dual AC power paths all the way up to the critical
load for the ultimate in AC power system redundancy, power availability and fault
tolerance.
Ideal Applications
- Data Processing
- Distributed Computing
- High Tech Manufacturing
- Other Critical Loads
Product Features
- Fast switching between two AC power sources makes power transfer time invisible
to your protected equipment.
- Manual and automatic transfer capability.
- Selectable preferred input source without rewiring or load shutdown provides application
flexibility and facilitates load balancing.
- Integral maintenance bypass to both input sources for servicing convenience.
- Hot-swap electronics allow module replacement without load shutdown.
- Switched neutrals maintain isolation of the separate power sources and simplify
grounding.
- Break-Before-Make switching eliminates connecting together of the independent power
sources, even under faulted conditions.
- Diagnostics and transfer tests detect potential switch failures before the problem
becomes critical.
- Output receptacles are available to match your load specifications, simplifying
system installation.
- The NEMA 12 enclosure may be placed under a raised floor, mounted on a wall or used
in a rack, based on your site needs.
- ETL Listed to UL Standard 1008 for safety.
- CE marked, complies with EMC and low voltage directives.
