Cosel adds 80-W DC/DC converter to value-added platform

Update: September 22, 2021

Cosel Co., Ltd. has expanded its value-added STMGF platform with the addition of an 80-W DC/DC converter. Available in two versions, the STMGFS80 covers a wide input voltage range from 9 V to 76 V.

The STMGFS8024 operates from 9 VDC to 36 VDC for 12-V and 24-V systems, while the STMGFS8048 works from 18 VDC to 76 VDC, covering industrial 24-V and 48-V systems. Four output voltages are available, 3.3 V/18 A, 5 V/16 A, 12 V/6.7 A, and 15 V/5.4 A. The output volage can be adjusted by a potentiometer included on the motherboard. The STMGFS80 has a typical efficiency of up to 92%.

Using Cosel’s MGFS80 DC/DC converter assembled on a carrier board, the STMGFS80 series fits in the same footprint as its predecessor, which previously only delivered 30 W. The STMGFS80 is ready to use out of the box and includes terminal blocks, an output voltage potentiometer, an input filter, and extra capacitors. The series complies with safety standards UL62368-1 and C-UL EN62368-1.

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

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

The open frame STMGFS80 series measures 52 x 29 x 117 mm (2.05 x 1.14 x 4.61 inches) and weighs 170 g max. It can be assembled directly to the end equipment chassis by fixing the base plate using the two mounting holes. It can also be clipped to a DIN rail chassis by ordering option (N2). Additional options will be available, including a plastic cover (N1) or combined DIN and cover (N3).

The STMGFS80 series has a five-year warranty and conforms to the European RoHS, REACH, and Low Voltage Directives.
