BF-TR8500 50W DMR Repeater 10-50KM Walkie Talkie Repeater with 99 Channels for Handheld Transceivers

Description:
Cost-effective DMR Repeater
BF-TR8500 is a full-band high-power digital repeater based on DMR/PDT protocol. It can effectively solve the problems of large-area network coverage, conventional single-base station communication, multi-base station networking, cross-regional command and dispatch, and frequency resource shortage, meeting the strict requirements of any conventional or cluster communication scheme. It can be used in airports, terminals, logistics and transportation, large hotels, etc.

High-power Full-range Design
The BF-TR8500 digital repeater offers a full-band design. It supports a maximum transmit power of 50W. Users can choose better transmission power according to their own business needs. It can flexibly meet the different frequency needs of various industries at home and abroad, and help users achieve a significant increase in communication coverage.

Standard Rackmount Structure
The DMR repeater adopts a standard 19-inch 2U structure. Its built-in fan and metal shell are used for heat dissipation. Users can install an appropriate duplexer into the chassis, eliminating the need for an external duplexer to avoid taking up additional space and making it more flexible to use.

Main and Standby Power Supplies
The BF-TR8500 digital repeater's built-in power supply supports AC power supply from mains electricity and DC power supply (such as a storage battery or a DC power supply). When the AC power supply is interrupted, the DC power supply can be used as a backup to restore the equipment to normal operation, ensuring that it is always on call in case of emergency.

Rich Application Features
1. Float charge: When the repeater is operating with AC power, the DC port can provide a floating charge current of up to 1A to charge your battery. This ensures that the battery can play a backup role in the event of a mains power outage.
2. USB programming: It supports a common USB data interface for programming and maintenance. Maintenance personnel do not need to delay maintenance work because they cannot find a dedicated programming cable.
3. Relay back-to-back: The device supports back-to-back functionality through the ACC interface.
4. Fault indication: When the equipment is in an abnormal working state, it will send out a fault prompt sound, and the digital display will prompt the fault code, which is convenient for maintenance personnel to quickly determine the cause of the fault and carry out maintenance and repair in time.
