Overview
The Lambda LNS-Y-24 is a 125W regulated linear power supply designed for servo drives, amplifiers, and industrial control systems requiring stable 24VDC output. Manufactured by TDK-Lambda, this unit features dual input voltage selection, making it suitable for global installations. The LNS-Y-24 is discontinued by the manufacturer but remains a reliable choice for maintenance, replacement, and retrofit applications where low-noise, regulated DC power is critical.
Key Features
- 125W regulated output—sufficient for mid-range servo amplifiers and multi-axis control systems
