Important power information
An ATS switches between available power sources; it does not generate backup power or replace a UPS. Both incoming feeds must be correctly rated and suitably protected. Keep the connected load within the rating of the selected ATS and its upstream supplies.
The C20-input model does not include input leads. Order two suitably rated IEC C19-to-C20 leads separately and confirm their compatibility with the source supplies.
Frequently asked questions
Does this replace a UPS?
No. The ATS transfers the load between two available AC sources. It does not provide stored energy or create a backup supply.
Are the C20 input leads included?
No. The AT-120-04-2XS1 requires two compatible input leads, ordered separately. The 16A and 32A commando versions include attached three-metre leads.
Can iPower build another configuration?
Other inlet, outlet and enclosure combinations may be available for project requirements. Send us the required rating, connections, outlet types and quantity.
