Break before make transfers
Break time < ¼ Cycle
Will not transfer faults
Small 1RU Design
Passively Cooled
One touch transfer
Better than relay based
Voltage free contact
Preferred source selector
Supported current up to 32A
Features
• Fast, reliable switching
• Transparent transfer – less than ¼ cycle.
• Solid state devices are far superior to their electro-mechanical equivalents.
• Dual redundant internal power sources.
