Using the АП1 power adapter as an instantaneous solid-state transfer switch for the control supply.

Use of the АП1 power adapter as an instantaneous solid-state transfer switch for the control supply.

ATS equipment work on the following algorithm: at faults* on the incomer 1 main source occurs transfer to supply from 2 standby source, at restoration of the initial supply voltage occurs reset to supply from 1 main source.

В ATS on electromechanical contacts during transfer between sources there is a brief interruption of the supply to the load. Loss of supply may lead to к failure the order of operations controller software, releasing the relay self-latching i contactors, reset i restart time relays etc.

АП1 power adapter is a solid-state micro-ATS control supply with instantaneous transfer time.

АП1 has Two equivalent supply inputs, and also common "N" input, which is connected to the common neutral. Output voltage АП1 is 12 V DC, load current – up to 200 mA. If there is two three-phase incomers, supply inputs АП1 it makes sense connect к phases of different incomers. This will supply load when voltage is present on at least one of the incomers.

АП1 power adapter is designed to supply electronic relays and controllers, БУАВР units and other loads, requiring an uninterrupted supply 12 V DC. Used also to supply БУАВР.х.х.х units from 0.4 kV busbars of transformer substations under operating, adapter i emergency substation operating conditions

In a number of cases, using АП1 makes it possible to replace an uninterruptible power supply (UPS). Solution с using АП1 has dimensions tens of times smaller, weight i cost. Besides АП1 has no battery requiring periodic replacement.

*fault – this covers: loss of all three phases of an incomer, loss of any one phase, and phase voltages going outside the set limits.
