The system consists of two identical plug-in supplies, each capable of delivering the full rated output power of the system, in a fully wired rack mounting assembly equipped with input switches, voltmeters, front panel output voltage adjustments and failure alarm circuits that provide the user with a set of Form C (SPDT) dry contacts that may be used to control an external alarm or other circuitry; they switch if either supply's output voltage deviates by 2V or more from the nominal.

Options include built-in audible alarms and ammeters.

The systems operate on inputs of 90-265V AC, 49-420Hz, single phase.

Each power supply has a separate set of input connections, so that two sources of input power may be used to have input power redundancy.

Standard models are available with outputs from 3.3 to 125V DC, to 276W, priced from US $1390 each.

Acopian guarantees to ship within 9 days.

A five year warranty applies. Request a free brochure from Acopian Power Supplies ...
