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%.
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.
