Overview
Product description
BMS series cascadable headend multiswitch with redundant dual power supply for 1 satellite in a 19″ rack-mountable enclosure.
No regular service and maintenance are needed during operation.
Headend Multiswitch, 1 Satellite (4 Sat-IF) + RF in, 12 Users out
BLANKOM Multiswitch optimized for use in Headends. 4 in/12 out+RF cascadable and non-cascadable Multiswitch for distribution of satellite signals from 1 satellite position (4 polarities) to 12 users. Redundant power supply, designed for heavy-duty use, in a 19″ 1 RU rack-mountable enclosure.
Features & capabilities
Features
BLANKOM BMS-0512C is a high-performance 1x Satellite Multiswitch for digital TV broadcasting Headend systems with a high-end performance.
Designed for the modern 19’’ rack mounting installations. This professional Multiswitch can be cascaded and is useful to grow with your demands. If more receiver outputs are needed, simply add a second device in your 19’’ Rack. (Up to 8 cascading devices in one chain are possible.)
The LNB power can be set to ON or OFF to be almost flexible for the combination with non-powered devices like optical LNB or similar optical transmitter – receiver couples like the BLANKOM BFT-44 (4x fiber transmitter) to BFR-44 /4x (fiber receiver).
LEDs are showing the actual status, as well as gain adjustments for the 4 SAT levels, securing a flexible installation even with multiple LNBs supported.
- 4 SAT-IF inputs, 1 terrestrial input, 12 receiver outputs
- Active terrestrial band input (passive optional available)
- 5 cascade throughput (models BMS-0512C, BMS-0512C* only)
- 19″ 1 RU rack mountable enclosure
- Dual (redundant) power supply
- Up to 7 cascaded Multiswitch possible
- Low-power consumption
- LNB powering ON/OFF selectable
- LNB supply 13-18V, 13V-18V+22 kHz = QUAD LNB compatible
- DiSEqC 1.0 support
- 950-2150 MHz and 47-870 MHz lossless sharp filter design
- Trunk loss is on average less than 2 dB
- High isolation between outputs
- Output port protection up to 100 Volts
- LED indicators for each output
- High performance isolated industrial power supplies
- Professional RF design for DVB IPTV and Digital Headend’s
