Introduction
E-1201 is one combined fixed channel mini-modulators unit that is developed according to space-saving, durable, and high performance design principle. It is composed of 12 mini-modulators, and one highly efficient switching power supply that are all vertically installed in one 3U sized standard rack. For each modulator, concentrated power supply, and internal combining mode are applied to allow system debugging simple and reliable. The 3U sized standard rack can either be installed on 19-inch cabinet, or is flexible to apply wall-hanging mode. Each modulator’s channel is displayed by LED serial number. You will easily find the channel number by checking the Serial Number and Channel Number Reference Table on the panel.
Features

l 5V power supply circuit enables operation at mildly warm status.
l The switching power supply applied is applicable to voltage 100~280V.
l Equipped with built-in combiner, no need to install additional combiner.
