Vadodara based electronika enterprises offers hpha1 series of harmonic attenuators manufactured by pico electronics-usa, a perfect front-end solution for universal ac or 3 phase input/dc output applications. The standard 2.5" x 4.6" x 0.5" footprint is one of the smallest available in the market in this power range offering a 365v regulated dc output, it can be used as a front end for pico"s fd/ md/ lfd/ lmd/ lpd/ pd and hpd series of dc-dc converters, which can provide from 3.3 v to 300 v dc. Also many laser and motor applications are able to use the hpha1"s 365 v dc output directly. It has a universal input voltage [47 to 440 hz] from 85 to 250 v ac and its output power is 1000w [derate from 110 v ac to 85 v ac at the rate of 1.2 percent per volt]. Its power factor is 0.99 [from 50 percent to 100 percent fl] [50 to 60 hz]. For systems needing synchronization, a 100 khz synchronizing signal is available by synchronizing pin. The enable pin ensures that the pico dc-dc converter doesnot get activated until the output of the hpha1 is within acceptable limits. Its efficiency is 90 percent or better [95 percent minimum from 170 to 250 v ac or for three-phase input]. The operating temperature ranges from 00 c to +850 c base plate with no power derating required, facilitating a regulated 36+++5 v dc output for many motor, laser and direct drive applications.
