Overview
The Lambda LOS-Z-5 is a regulated AC/DC power supply engineered for reliable low-voltage DC power delivery in industrial control and instrumentation applications. Lambda LOS-Z-5 units feature fixed 5V output with current-limiting protection, switchable AC input voltage, and a modular enclosure suitable for board mounting or standalone rack installation. This used, tested unit is fully functional and represents significant cost savings for facilities and integrators stocking redundant power architecture.
Key Features
- Fixed 5VDC output with 3A maximum current rating at 40°C ambient
- Dual-voltage AC input: 105–125VAC or 210–250VAC, 47–63Hz operation
- Voltage-regulated for line and load, with inherent current-limiting protection
- Compact modular frame construction for cabinet or DIN-rail integration
- Tested fully operational; ready for immediate deployment
