Value-added DC-DC converter platform with 80W unit for industrial applications

COSEL Co Ltd has added an 80W DC-DC converter to its value-added STMGF platform. Offered in two versions, the STMGFS80 covers all industrial voltages from 9V to 76V. Using its efficient MGFS80 DC-DC converter assembled on a carrier board, the STMGFS80 series fits in the same footprint as its predecessor, which previously only produced 30W. Ready to use out of the box, it includes terminal blocks, output voltage potentiometer, input filter and extra capacitors. The series complies with safety standards UL62368-1 and C-UL EN62368-1.

Battery-powered industrial applications need very efficient power solutions, and system developers are endeavouring to decrease the number of references when choosing a power supply. They also want easily mountable power sources such as DC-DC converters within their equipment.

Combining the company's high efficiency, wide input range DC-DC converter modules with a robust mechanical platform, its Value Added STMG platform provides designers with an easy way to obtain the benefits of a high-quality power solution in an industrial mount packaging.

The series is offered in two models. The STMGFS8024 operates from 9VDC to 36VDC, embracing 12V and 24V systems, and the STMGFS8048 works from 18VDC to 76VDC, covering industrial 24V and 48V systems. Four output voltages are available, 3.3V/18A; 5V/16A; 12V/6.7A and 15V/5.4A. Output voltage may be adjusted by a potentiometer incorporated on the motherboard.

All modules incorporate an ON/OFF remote control function through an interface connector. Negative logic is the standard method employed to control ON/OFF through the remote function, although positive logic RC can be offered on request (Option R).

Benefiting from its high-efficiency topology, the STMGFS80 offers a typical efficiency of up to 92%.

Optimised for convection cooling, the power supplies may be operated within an ambient temperature range of -20C to +70C. Depending on the assembly method and ventilation levels over the final equipment, a derating can apply as specified in the technical documentation.

The series incorporates overvoltage and overcurrent protection. In the case of overcurrent exceeding 105% rating, the module functions in hiccup mode and automatically recovers when the output current returns to normal.

For safety and galvanic isolation, the series has 1,500VDC Input and RC to Output, 1,000VDC Input and RC to FG and 1,000 VDC Output to FG. It can be assembled directly to a customer’s equipment chassis by fixing the base plate utilising the two mounting holes. It can also be clipped to a DIN rail chassis by ordering the option (N2). Open frame type, the series measures 52mm x 29mm x 117mm (2.05" x 1.14" x 4.61") and weighs 170g max.

The series has a five-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives.
