Xantech's ERGPS energy efficient-regulated, 12-volt DC power supplies are packaged with the IR kits. Two models are available for other IR-based installations. The 781ERGPS will replace the 781RG power supply, and the 782ERGPS will replace the 782-00. The power supplies are packaged in a smaller form factor. A secure-fit plug interfaces with Xantech IR connecting blocks. A small indentation on the secure-fit plugs allows a tight and secure connection every time.
