About the 705309-39R
705309-39R Field Supply Assembly
The 705309-39R is a Reliance Electric component manufactured for use with the company’s drives. Most of Reliance’s products are marked with their logo and shipped with Reliance branded paperwork (manuals, etc.) However, due to changes in company structure, it is possible your current component originated from either Baldor-Reliance or from ABB. If there are any questions about compatibility between your current part and this listing, please contact our team.
The 705309-39R functions as a field supply assembly. This component is designed from a three-sided metal housing with two right-angled flanges drilled for mounting located at the bottom of both vertical sides. The housing has a back panel but is open to the front. Most components are mounted either directly to the back panel or are part of the small circuit board screw-mounted to the bottom right corner of the panel.
The previously mentioned board component portion of the 705309-39R is populated by two transformers, diodes, resistors, several terminal pins, and multiple cable connectors. This circuit board is numbered 0-51378-27. This is a gate coupling board. Other components mounted within the housing include metal oxide varistors, a Dale power resistor, an inductor coil, and an oscillator. The housing has openings in its side and top edges to allow cables through to their proper destinations.
