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 ~ 100°C Baseplate Operation – Standard -55 ~ 125°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 330-400KHz (Optional) • 2 Year Warranty ORDERING INFORMATION Model Number uV300-12-164 Input Voltage Range Output Voltage 220-400 VDC 12 (10.8-13.2 VDC) Output Current 25A uV300-12-XXX-164YY XXX YY S= Synchronization 330-400KHz RL= No Pure Tin T= -55°C to 100°C Operating Temperature LF= RoHS Compliant C= Conformal Coating no suffix is required for E= -55°C to 125°C (Consult the factory for output power rating) standard tin-lead finish Part Number Example: uV300-12-STC-164RL Synchronization, -55°C to 100°C, Conformal Coating, No Pure Tin www.astrodyne.com www.roassoc.com Astrodyne USA: 1-800-823-8082 Astrodyne Pacific: 886-2-26983458 uV300-12-164 300 VDC Input / 300 Watts / 3/4 Brick ABSOLUTE MAXIMUM RATINGS Exceeding absolute maximum ratings may cause permanent damage or reduce reliability Parameter Option Minimum Maximum Units Conditions Input Voltage ( + In to -In) -0. 3 400 VDC Continuous Transient Input Voltage (+In to -In) -0. 3 100 msec.
