XP Power MTC30 Series DC Power Supply MTC3028S28

The MTC3028S28 is a DC power supply from the MTC30 Series by XP Power, designed to operate within an input voltage range of 15.5 to 40.0 VDC, with a transient input capability of up to 50 VDC for short durations. This model provides a nominal output voltage of 28.0 VDC and can deliver a maximum output power of 35 W. It features no minimum load requirement and offers line and load regulation of ¬±1% of the nominal output voltage. The power supply includes several protection features such as overvoltage protection (110-120% of Vout), overcurrent protection (105-150% at nominal input), and short circuit protection with a trip and restart mechanism. The operating temperature range is from -40 ¬8C to +100 ¬8C, with an extended range option available down to -55 ¬8C. The unit is designed for high reliability in demanding environments, meeting various military standards including MIL-STD 461 and MIL-STD 1275. With a switching frequency of approximately 450 kHz and a power density of 14.5 W/in¬=, the MTC3028S28 is suitable for applications in vetronic and avionic systems. It also features a maximum capacitive load of 300 ¬µF at startup and a startup time of less than 100 ms. The product is backed by a three-year warranty, making it a robust choice for engineers seeking a reliable power supply solution.
