TMU 3 3W Isolated DC/DC Converters

TRACO Power TMU 3 series are 3W Isolated DC/DC Converters with unregulated outputs in a standard SIP-4 package. The TRACO Power TMU 3 3W Isolated DC/DC Converters provide a cost-effective alternative to regulated DC/DC converters with no compromise in quality or lifetime. The series features continuous short circuit protection, 1500V_DC I/O isolation, and a convection cooled –40°C to +75°C full load operating temperature range. These compact converters are ideal for use in space-critical applications in communication equipment, instrumentation, and industrial electronics.
