7 / 9 page Rev C JFCW30 SERIES 30 Watt DC/DC Power Converter Single and Dual Output 02/27/2017 Wall Industries, Inc. • 37 Industrial Drive, Exeter, NH 03833 • Tel: 603-778-2300 • Toll Free: 888-597-9255 • Fax 603-778-9797 website: www.wallindustries.com • e-mail: sales@wallindustries.com Page 7 of 9 OUTPUT VOLTAGE ADJUSTMENT Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting an external resistor between the Trim pin and either the +Output or –Output pins. With external resistor between the Trim and –Output pin, the output voltage set increases. With an external resistor between the Trim and +Output pin, the output voltage set point decreases. The external Trim resistor needs to be at least 1/16W of rated power.
