1 Astrodyne Corporation Tel: (08) Hampden Road Fx: (08) Mansfield, MA sales@astrodyne.com MICROVERTER -164 DC/DC Converter 300 Input 300 Watts 3/4 Brick The MICROVERTER 164 Series is a second generation product which combines high efficiency electrical power design and proprietary advanced thermal management techniques including insulated metal substrate technology, specialty dielectrics and formulated thermally conductive potting to produce small, ruggedized DC/DC converters with reduced temperature rise and increased reliability. This series is ideal for use in rugged, thermally challenged applications requiring baseplate cooled operation such as military systems, RF/power amplifiers, commercial avionics and industrial control. All RO products are normally manufactured using a tin-lead soldering process. The MICROVERTER 164 Series is also available in both full RoHS compliant (utilizing lead free solder) and full tin-lead (no pure tin) configurations. All models are designed to meet international safety standards. OPERATIONAL FEATURES Encapsulated & Environmentally Rugged Package Extremely Low Thermal Resistance -40 ~ 0 C Baseplate Operation Standard - ~ 12 C Baseplate Operation Optional Constant Frequency Operation for Reduced Noise Remote On/Off, Parallel and Remote Sense Functions Auto-Recovery from OTP / OCP / OVP Circuits Trimable Output Synchronizable from KHz (Optional) 2 Year Warranty ORDERING INFORMATION Model Number Input Voltage Range Output Voltage Output Current ( ) 11A XXX uv xxx-164yy S= Synchronization KHz RL= No Pure Tin T= - C to 0 C Operating Temperature LF= RoHS Compliant C= Conformal Coating no suffix is required for E= - C to 12 C (Consult the factory for output power rating) standard tin-lead finish Part Number Example: uv stc-164rl Synchronization, - C to 0 C, Conformal Coating, No Pure Tin YY
