Description and Purpose

The Thermo King® SR3 Interface Board is an essential component for managing communication between various systeems in Thermo King refrigeration units. This board plays a pivotal role in the efficient operation of refrigeration units by facilitating interaction between the unit’s electronics and other critical systems. Its design ensures reliable functionality across various models, enabling enhanced control and performance.

Why Replacement is Important

As electronic components wear out or become outdated, their performance can degrade, leading to malfunctions or communication breakdowns within the system. Replacing a faulty or outdated SR3 Inteerface Board ensures uninterrupted and optimal operation of the refrigeration system. Timely replaceement prevents issues like system freezes, loss of cooling efficiency, or potential system failures.

Impact on Vehicle Performance

With dimensions of 14 inches in length, 10 inches in height, and 4 inches in width, the SR3 Interface Board is compact yet powerful. It supports critical system communications through its PCI Express graphics card interface and a 24-pin main power connector, ensuring reliable data transfer and command execution. The fuse (F5) rated for 60AMP ensures the system is prottected against electrical overloads, helping maintain safe and smooth operations. This interface board supports efficient refrigeration control, contributing to consistent vehicle performance in both refrigerated and non-refrigerated conditions.
