Holland Electronics HMMS Mini Modulator Series Ch.#2 - Ch.# 135
CMHO54XX-1
Details
***Please specify the channels that you need for your head end system***
The HMM Modular Head-End system consists of a 12-slot mounting rack and power supply capable of holding 12 high quality SAW modulators and/or demodulators. The easy slide-in mounting system uses only a 3.5" rack height, making installation easy and space efficient.
Installation is as easy as sliding in the module and plugging in the VDC power.
SAW Filtered, PLL Controlled Modulators
Microprocessor Based Demodulators
Fan Cooled Power Supply For Extra Reliability In Warm Environments
Stereo Encoder Available
Switching Power Supply Works from 95-240 VAC
Front Panel Controls
