Why Engineers Prefer the LPS-75-12
Application-Specific Advantages
Industrial Automation:
The converter's -20 C to +70 C operating range (with derating above +50 C) ensures stable performance in harsh environments. Its 3000m altitude rating and <5% output ripple make it ideal for CNC machines, PLC systems, and test equipment.
ITE/Telecom Solutions:
CB/CE/cURus/TUV certifications guarantee compliance with EN/UL 62368-1 safety standards for IT equipment. The remote on/off control (via 4-8VDC signal) enables smart power management in server racks and network switches.
