80W DC-DC converter for industrial applications
The Cosel STMGFS80 DC-DC converter fits in the same footprint as the previous 30W design with easy system integration by baseplate and DIN rail attachments

Cosel has expanded its STMGF DC-DC converter range with an 80W variant for industrial designs.

The STMGFS80 covers all industrial voltages from 9V to 76V and uses the MGFS80 DC-DC converter assembled on a carrier board to fit the same footprint as its 30W predecessor. The DC-DC converter includes terminal blocks, output voltage potentiometer, input filter and extra capacitors and complies with safety standards UL62368-1 and C-UL EN62368-1.

Battery powered industrial applications require very efficient power solutions, and system developers are seeking to reduce the number of references when selecting a power supply. They also want easily mountable power sources such as DC-DC converters within their equipment. The topology gives an efficiency of 92 percent with easy mounting in industrial designs.

The STMGFS80 series is available in two models. The STMGFS8024 operates from 9VDC to 36VDC for 12 and 24V systems, and the STMGFS8048 works from 18VDC to 76VDC, covering industrial 24 and 48V systems. Four output voltages are available, 3.3V/18A ; 5V/16A ; 12V/6.7A and 15V/5.4A and the output voltage can be adjusted by a potentiometer included on the motherboard.

All modules include an ON/OFF remote control function via an interface connector. Negative logic is the standard method used to control ON/OFF via the remote function, although positive logic RC can be provided on request (Option R).

The DC-DC converters can be operated within an ambient temperature range of -20 to +70 degrees centigrade with convection cooling. Depending on the assembly method and ventilation levels across the final equipment, a derating may apply as specified in the technical documentation.

The STMGFS80 series includes overvoltage and overcurrent protection. In the case of overcurrent exceeding 105% rating, the module operates in hiccup mode and automatically recovers when the output current returns to normal.

For safety and galvanic isolation, the STMGFS80 series has 1,500VDC Input and RC to Output, 1,000VDC Input and RC to FG and 1,000 VDC Output to FG.
