860MHz Combined fixed Channel Modulator (CSP1200)
 860MHz Combined fixed Channel Modulator (CSP1200) |
Product Description
CSP1200 is one combined fixed channel modulators unit that is developed according to space-saving, durable, and high performance design principle. It's composed of 12 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 mixing mode are applied to allow system debugging simple and reliable. The 3U sized standard rack can either be installed on 10-inch cabinet, or is flesible 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 Mumber channel Mumber and Channel Number Reference Table on the panel.
IF processed, double PLL circuit.
5V power supply circuit enables operation at mildly warm status.
The swiching power supply adopted applicable to voltage 100-280v
Equipped with built-in mixer, on need to install additional mixer.
