Samlex Heavy Duty Non-Isolated Step-Down DC-DC Converter

This high efficiency switch-mode step-down DC-DC converter converts an input voltage of 24V DC nominal (range 20V DC to 35V DC) to a highly regulated output voltage of 12V DC nominal (13.8V DC) at 5A/30A. The SDC DC-DC converter is non-isolated (no galvanic isolation between input and output) and meant for use in negative ground systems. Features include short-circuit, reverse polarity and over-voltage protection. This DC-DC converter is designed for heavy duty applications.

Features:
