Other brands are what, please specific models have the best manual
In addition, I do not understand why the design of the dual power supply conversion time so high? What are the devices or devices that require 0.5 seconds?
Thank you to answer the perfect set points
Change the transition period? Similar to the strict requirements of the same period is the grid, requiring phase sequence, voltage, frequency are the same.
UPS and dual power switch is not a concept, like your phone to change the use of charging, there is no power switch problem, because they are battery-powered, nothing more than the battery at the same time whether the charge in the charge.
More detailed on the power switch problem I can not reply, I was engaged in industrial control -_- !!!
But from the actual use of view, in fact, you still mention the point of the most critical, which devices and equipment on the dual power supply switching have different needs, from my contact, such as the Pudong Airport runway lights double power, oil machine Three-way power supply) switching time requirements are concerned, is not more than 15 seconds. Other more stringent requirements, really did not encounter.
The requirements of the design institute are not all reasonable, rigid dogma is that they are not aggressive or they are.
ATS series of conversion time is certainly> 0.5 seconds, and dual power switch is not as fast as possible, in half an alternating cycle to detect the power failure is not possible, Schneider other series of dual power switch Also in more than 0.5 seconds. And this time can be artificially set, such as the detection of common power failure, the delay t1 disconnect the commonly used circuit breakers, and commonly used circuit breaker unloading load to the standby circuit breaker closing time t2, common power recovery, standby power Exit time can be set.
This request is not high, generally in the industry dual power switch required time is mS level, that is less than a power cycle of the exchange. You are already very loose.
