The Astrodyne TDI MCA30 series, including the MSCC-0300 model, offers 30W ultraminiature modular switching power supplies designed for performance and reliability. These units feature a universal 90 to 264 VAC input, making them suitable for global applications. The operating temperature range is from 0 to +50°C in free-air convection.
Key electrical specifications include an input frequency range of 47-440Hz, with typical values of 50-60Hz. The power supply provides 3000 VAC of input-to-output isolation, 1000 VAC output-to-ground isolation, and 2500 VAC input-to-ground isolation for enhanced safety. It has a typical operating frequency of 140 kHz and features over-voltage protection, continuous short-circuit protection, and current limiting.
The MSCC-0300 is designed for chassis mounting and has dimensions of 4.76" L x 2.56" W x 1.00" H (120.9mm x 65.0mm x 25.4mm). It weighs 380g (13.4 oz). The power supply meets safety standards such as UL60950-1, C22.2 60950-1, EN60950-1, EN60601-1-2, and IEC60950-1, with CE and cURus approvals.
Applications for this series include ITE (Commercial) and Medical equipment. The power supply also includes features like universal input and an on/off control function.
The input voltage range is 90-264 VAC, with nominal 100-240 VAC.
The output voltage is adjustable from 3.3 to 24 VDC, with a ±6% trim range.
The operating temperature range is 0°C to 50°C at full load, with derating.
The dimensions are 120.9mm x 65.0mm x 25.4mm (4.76" x 2.56" x 1.00").
It has UL/cUL, UL-EU, CE, and CB approvals, conforming to UL60950-1, EN60950-1, EN60601-1-2, and IEC60950-1.
Input-output isolation is 3000 VAC, input-ground is 2500 VAC, and output-ground is 1000 VAC.
The MTBF is 180,000 hours at 25°C per MIL-STD-217 for single output models.
