The AEP-A3000R series of pure-sign-wave inverters provide 3-kVA power in a 1U rack and is available in standard input configurations of 24 and 48 Vdc. Outputs are regulated to ±3% or better. A built-in, 4 to 6-ms automatic bypass switch allows redundant operation from utility power if the dc supply drops out. In UPS mode, the ac input is not needed for standard inverter operation.
The inverter series features protection circuitry and a front-panel digital display that indicates low/high input voltage, overtemperature, and overload conditions. The display also indicates volts, amps, watts, and temperature. The device features 87% to 90% efficiency. (From $2,299 ea/100 – available now.)
