Very high-reliability 80W DC-DC converter for demanding applications

11-09-2019 | Cosel | Power

Cosel Co Ltd has released a very high-reliability 80W DC-DC converter, the MGF80. Packaged in an industry-standard 2" x 1", six-sided, shielded metallic case, the series has been created to the company's strict criteria for high performance and reliability, contributing to the company’s world-class quality with a failure rate of less than 30 parts-per-million. All components are chosen for a very long lifetime, making the device one of the most reliable DC-DC converters in its category. Consequently, the company backs up the series with a long, confidence-inspiring warranty period of 10 years. To guarantee lifetime quality, the device does not include aluminium or tantalum capacitors.


Satisfying a large range of critical applications, the series is offered in two input voltages, 9V to 36V and 18V to 76V. A single output version, the MGFS80 is offered in four output voltages, 3.3, 5, 12, and 15V, and can be modified within a range of +/- 10% utilising a resistor bridge or potentiometer. A dual-output version, the MGFW80 is provided in two factory-trimmed output voltages, +/- 12V and +/- 15V, giving the possibility to offer respectively, 24V and 30V between the two ends.


Built with robustness in mind, the rugged series has been tested to sustain rough conditions and has passed three-axis vibration testing equivalent to 10G and shock testing of 50G.


Housed in a six-sided, brass, nickel-plated housing measuring an industry-standard 50.8mm x 25.4mm x 9.9mm (2" x 1" x 0.39"), the unit uses lead-free plated copper pins. Weight is just 50g.


The series has input-output isolation of 1500VDC, and an input and output to case isolation of 1000VDC. It is UL62368-1, C-UL [CSA62368-1) and EN62368-1 approved and CE mark 2014/35/EU. The MGFS80 and MGFW80 are RoHS compliant.
