Output voltage programmable from 0.6V to 3.3V, 0.59V to 6.0V, 3.0V to 6.0V, and 5.0V to 15V by connecting a single resistor between the TRIM and GND pins of the module. To calculate the value of the resistor (Rtrim) for a particular output voltage (Vo), use the equations shown in Table 1. 2. CV12S3.3-3000: When using negative output application, |Vo| trim up > 3.3V and the output current is 1.5A max. 3. CV12S3.3-3000: When Vo,set < 0.9VDC the input voltage range is 4.5 ~ 9 VDC. 4. Both vertical mounting and horizontal mounting SIP types are available. Add the suffix “A” to the model number for horizontal mounting SIP type. 5. CAUTION: This power module is not internally fused. An input line fuse must always be used. *Due to advances in technology, specifications are subject to change without notice. 01/02/2013 Wall Industries, Inc. 37 Industrial Drive Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 Page 3 of 6 CV Series 1.8 to 45 Watts Adjustable Output Voltage Non-Isolated DC/DC Converters Rev.
