LD / LDS Series Linear Power Supply

The LD / LDS Series from Lambda is a family of linear regulated power supplies designed to provide stable DC output for industrial and instrumentation applications. These units use transformer-based designs with rectification and filtering to deliver clean, well-regulated voltage from AC line input.

The series spans a broad range of output voltages, from low-voltage models around 5 to 28 volts up to higher-voltage units reaching 100, 120, and 150 volts. Several adjustable-range models are also included, such as 0–7, 0–18, and 0–32 volt versions. Power ratings across the series vary by frame, with input power classes including 155W, 230W, 293W, and 430W.

Common Applications

• Industrial control systems
• Test and measurement equipment
• Electronic instrumentation

Typical units feature adjustable output voltage and screw terminal connections, making them suitable as replacements across a wide variety of fixed and variable DC supply requirements.
