The Astrodyne TDI MSCA-0303 is a 30W ultraminiature modular switching power supply. It operates with a universal input voltage range of 90 to 264 VAC and a frequency of 47 to 440 Hz. This converter is designed for ITE (Commercial) applications and features an efficiency of 80% and a single output.
Key electrical specifications include an output current of 2A, an initial accuracy of ±1%, and load/line regulation of ±0.3%. It offers robust protection features such as over-voltage protection (130-150%), continuous short circuit protection, and a current limit of 130% typ. The unit provides 3000 VAC input-to-output isolation, 1000 VAC output-to-ground isolation, and 2500 VAC input-to-ground isolation.
Mechanically, the MSCA-0303 is housed in an 8-DIP module with 5 leads and is designed for Through Hole mounting. Its dimensions are 88.9mm x 63.5mm x 24.9mm. The operating temperature range is 0°C to 50°C, with a storage temperature range of -25°C to +71°C. The case material is Rynite, rated 94V-0.
Safety approvals include CE and cURus, with compliance to standard 60950-1. The MTBF for single output is rated at 180,000 hours.
