Description
The Alpha Technologies 012-554-20-041 is an OEM CSM46 DC-DC Converter Module designed for telecommunications network and remote line powering applications. This modular converter transforms high-voltage DC input from distributed power networks into regulated -48V nominal DC output, providing reliable power conversion for remote telecommunications equipment. The module supports an input voltage range of 195 to 380 VDC and delivers up to 150W of output power.
The Alpha Technologies CSM46 Modular Converter System uses high-frequency switched-mode conversion technology to support centralized network powering over existing copper pair infrastructure. Each converter module incorporates two isolated DC-DC converter channels, rated up to 75W each, with built-in protection and monitoring features. Designed for installation in compatible CSM46 converter shelves, the module supports scalable power capacity, hot-swappable replacement, and integration with Alpha CSM36 upstream power conversion systems used in telecommunications network infrastructure.
