Power’s ARm-1000 redundancy module ~ automatic bypass system is
recommended when no downtime from power outage is tolerated. Internet
service providers, critical servers and telecom equipment, and export
markets with bad power would find this technology valuable. The ARm
Series permits daisy chaining with any UPS, providing unlimited
redundancy using any combination of independant (separate) ac circuits,
UPS systems, generator-backed ac circuits, and so on.
Typical ARm
series applications
Designed
for situations where reliability and predictability matter to the
enterprise.
Examples: telecommunications equipment, export markets, file
servers, routers, digital copiers, office machines, industrial
controllers (PLC), automatic test equipment (ATE), laboratory analyzers
and other sensitive, specialized microprocessor-based equipment.
Key automatic
redundancy module benefits
The ARm
will provide uninterrupted ac to your load even in the event of UPS
failure. ARms your critical equipment against
extended power outages and catastrophic system shutdowns caused by
accidental circuit breaker trips, UPS overload conditions, weak or old
UPS batteries, routine & preventive maintenance of UPS, accidental
UPS shut down, loose power cords, or UPS failure. ARm-1000E
permits unlimited redundancy using any combination of independent
(separate) 230V ac circuits, UPS systems, generator-backed AC circuits, etc.
How ARm automatic
transfer switches work
The ARm
is fed by two AC power sources. When the primary power source detector
circuit senses a loss of power on that circuit, a relay immediately
switches the load over to the backup power source feed in less than 10
ms. This is fast enough to be invisible to computer switch-mode power
supplies. |
