The FC 2KP-EW/A Series modular ac-ac frequency converter system was designed to deliver a clean sine-wave output from "dirty" generator voltage under extreme environmental conditions.

This 2kVA system converts a wide range varying generator voltage of 180V - 270Vac with a frequency range of 35 - 70Hz, to a stable 120Vac at 60Hz, which is required to run control circuitry and instrumentation in earthmoving equipment. This design can be adapted to similar requirements for other heavy equipment vehicles used in mining, excavation and oil exploration environments.

The FC 2KP-EW/A system employs field-proven, microprocessor controlled high frequency PWM technology, which enables compact construction and high efficiency. It is comprised of an AC-DC sub-system and a DC-AC sub-system, each housed in a separate low-profile, mechanically robust enclosure and mounted on a 508 x 69 x 914 mm base-plate. Conduction cooling is by base-plate which is attached to a heat-sinking surface. No fans are required.

To ensure immunity to the high levels of shock and vibration encountered in harsh environments, the internal modules in both sub-systems are entirely potted with thermally conductive MIL-grade silicon rubber compound. This also provides protection from high temperature, moisture and airborne contaminants.

Electronic protection features include 2250Vdc input to chassis/output isolation, over-voltage and short circuit protection with thermal shutdown and self-resetting. The system is filtered to meet EN55022 Class A conducted and radiated requirements with wide margins. It complies with C22.2 No. 107.1-01, UL 458 and EN/UL60950-1 and equivalent industrial safety standards.
