Includes wide input voltage and easy system integration by baseplate and DIN rail attachment with a robust mechanical platform
Battery-powered industrial applications require very efficient power solutions. System developers involved in their development seek not just reduced number of references when selecting a power supply, but also want easily mountable power sources such as DC-DC converters within their equipment.
Therefore, COSEL has now included the STMGFS80, an 80W DC-DC converter in its STMGF series. The STMGFS80 can cover industrial voltages from 9V to 76V in a compact footprint. Ready to use out of the box, the STMGFS80 includes terminal blocks, output voltage potentiometer, input filter and extra capacitors. By combining COSEL’s high efficiency, wide input range DC-DC converter modules with a robust mechanical platform, its Value Added STMG platform offers designers the benefits of a high-quality power solution in industrial mount packaging.
The STMGFS80 series is available in two models: the STMGFS8024, which operates from 9VDC to 36VDC and is suitable for 12V and 24V systems, and the STMGFS8048, which 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. 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 STMGFS80 has a typical high efficiency of up to 92%. The DC-DC converter is optimised for convection cooling and can be operated within an ambient temperature range of -20 to +70 degrees centigrade. Depending on the equipment assembly method and ventilation levels, a derating may apply.
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.
STMGFS80 can be assembled directly onto a customer’s equipment chassis by fixing the base plate using the two mounting holes. It can also be clipped to a DIN rail chassis by ordering the option (N2). Additional options e.g., plastic cover (N1) or combined DIN and cover (N3) will be available early Q2-2022.
Available in an open frame type, the STMGFS80 series measures 52mm x 29mm x 117mm (2.05 x 1.14 x 4.61 inches) and weighs 170g max. The series complies with safety standards UL62368-1 and C-UL EN62368-1, and conforms to European RoHS, REACH and Low Voltage Directives with a five-year warranty.
