PWR1726AC www.murata-ps.com 1.5 Watt Unregulated DC/DC Converter DESCRIPTIONDESCRIPTION FEATURES The PWR1726AC is a single-channel, bipolar output DC/DC/ 8000v Isolation Test Voltage converter designed for those applications where high-isolation voltage and low-barrier capacitance are critical for system reliability No External Parts Required and integrity. Remote On/Off Calculated mean-time-to-failure (MTTF) is in excess of 100 years at an ambient temperature of +25C and at rated output Low-Barrier Capacitance power. The performance of the PWR1726AC is not derated over its RoHS Compliant entire speci ed temperature range of -25C to +85C. Synchronization of the PWR1726AC may be accomplished Synchronizable simply by connecting the Sync-In pin of one unit to the Sync-In pin of another unit. Up to 8 converters may be synchronized in this manner. APPLICATIONS The PWR1726AC provides a plus and minus output voltage that is approximately equal to the magnitude of the input voltage. Biomedical Data Acquisition The unit operates over an input voltage range of 7VDC to 16VDC. Industrial Process Equipment Each PWR1726AC isolation barrier is tested per the method set forth by UL544, VDE750, and CSA C22.2.
