SynQor has premiered a new line of military commercial-off-the-shelf (COTS) products aimed at applications requiring large amounts of power in limited space.
The MCOTS Zeta line of DC-DC converters is designed to provide isolated DC power for electronics such as power amplifiers, jammers and systems requiring high-power bus voltages. These converters use SynQor’s synchronous rectifier technology to achieve efficiencies of up to 95% at full load. This performance allows the units to provide output power levels of up to 500 W in a standard half-brick package.
Switching frequency is constant to provide predictable EMI performance and the converters can be paired with SynQor MCOTS EMI filters to meet most requirements of MIL-STD-461. The devices are offered encased for high performance in harsh environments and can provide full output power at case temperatures between -55°C and 100°C.
Input voltage family ranges have been tailored to MIL-STD-704 and MIL-STD-1275 and include 28 (16 V to 40 V), 28V (9 V to 40 V) and 28VE (9 V to 70 V) with many output voltage offerings between 5 V and 50 V. The optional built-in current sharing feature allows for easy paralleling of modules for applications requiring more than 1 kW of power or module redundancy with limited external components.
Features include remote on/off control, +10% to -50% output voltage trim range, remote output voltage sense, input under-voltage lockout, output over-voltage protection and optional current share. The Zeta series is designed for 2250 V d.c. and 30 M input-to-output isolation, is 6/6 RoHS compliant, and is rated with MTBF values in excess of 1,3 million hours at 70°C (MIL-217).
