AC Front End Modules for Power Supplies

Filters and AC Front Ends for Power Systems

HAM – AC Harmonic Attenuator Module

The HAM module is a full-wave rectifier with a proprietary high-frequency zero-current switching (ZCS) boost converter providing up to 675 watts of power in a full-brick package.
measuring only 2.4" x 4.6" x 0.5".

AIM – AC Input Front-end Module

The AIM is an AC front-end module which interfaces directly with worldwide AC mains to provide line rectification, EMI filtering, transient protection, and inrush limiting. This module is used in conjunction with VI-200 or VI-J00 DC-DC converters to realize a universal AC input, high density, low profile switching power supply with outputs from 1 - 95 Vdc and a total power rating up to 200 W.

ARM – Autoranging Rectifier Module

The Autoranging Rectifier Module (ARM) is the front end of a switching power supply and uses a microprocessor to control strapping of the voltage doubler. The user only needs to add an input filter, hold-up capacitor and appropriate DC-DC converters to realize an autoranging, high-density, low-profile switching power supply.

Filter / Autoranginig Rectifier Module - FARM

FARM - Filter / Autoranging Rectifier Module

The FARM (Filter/Autoranging Rectifier Module) is an AC front-end module which provides EMI filtering, autoranging line rectification and inrush current limiting. The FARM is available in either 500/750 W or 750/1000 W models in a mini-sized package measuring only 2.28" x 2.2" x 0.5".
