Harmonic attenuators
Harmonic attenuators
Vadodara based Electronika Enterprises offers HPHA1 series of harmonic attenuators manufactured by PICO Electronics-USA. These are the 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. Providing 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. Its output power is 1000W (Derate from 110 V AC to 85 V AC at the rate of 1.2% per volt). Its power factor is 0.99 (from 50% to 100% FL) (50 to 60 Hz). For systems needing synchronization, a 100 kHz synchronizing signal is available by synchronizing pin. Enable pin helps in preventing the PICO DC-DC converter from turning on until the output of the HPHA1 is within acceptable limits. Its efficiency is 90% or better (95% 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. Regulated 36+++5 V DC output can be used directly for many motor, laser and direct drive applications.
