Unity Rectifier System

Newmar’s Powering the Network offers Unity Rectifiers. Telecom Hot Swap Rackmount Rectifier with 3-24 amps per system and 24-48 VDC.

Rectifiers and Battery System for Point-to-Point Microwave Transmitters

The Unity Rectifier System integrated with the Battery Module series creates a comprehensive DC power system providing 24 or 48 volts for point-to-point microwave transmitters along with an integrated battery back-up function for ride through when utility AC power is down.

The Unity Rectifier, model UR-48-3, provides 48 VDC at 3 amps per modular unit that inserts in a rack mount shelf, which accepts up to 3 modules for N, N+1, and N+2 configurations. In case of critical dependence on the wireless network, additional 1U Unity Rectifier modules provide critical systems with redundant DC power, thus ensuring high reliability. Model UR-24-6, provides 24 VDC at 6 amps per modular rectifier.

In situations of utility AC power failure, minimize transmitter down time with an easy to install battery back-up system. Using a modular approach, this system does all the hard integration work for you. No need to source battery cells, mounting trays, interconnect cables, terminals, lugs, and circuit breakers because they are all included in the Battery Module System. This system is ideal for backing-up low power to point-to-point microwave transmitters for broadband, assuring the system remains up when AC power is down. The 48 volt, 5 amp-hour modules provide easy scalability to meet reserve run time requirements. Each shelf accommodates two battery modules and shelves can be paralleled via modular connectors.

Application 1: Unity Powers School District’s Network

Newmar’s 48 volt Unity Rectifier System, model 48-3, was selected to supply primary DC power and maintain battery back-up for a multi-million dollar licensed microwave project for a large school district in Arizona.

The Unity series rectifier is powering transmitters which are linked by point-to-point microwave technology connecting 47 separate locations in the district including schools, warehouses, administrative offices and other facilities. The network provides the school district with high speed connections to Internet, as well as data, video, and voice systems to increase communication and learning in the classroom.
Because the school district has critical dependence on this wireless network, additional Unity Rectifier modules provide the wireless system with redundant DC power, thus ensuring a high reliability. Also, with limited rack space available the 1 RU low profile of the Unity Rectifier System, which only occupies 1.75” (1U) of vertical rack space, proved to be an important factor for system integration.

Application 2: Replacement Power Supplies for ‘Older’ Broadband Radios

Many older broadband radio networks utilize power supplies that are no longer supported by the manufacturer. When replacement is needed Newmar offers a DC power solution which prolongs the service life of the network. For example, manufacturers like Proxim have obsolete older radio models and their accompanying power supplies. Newmar’s Unity UR-48-3 Rectifier System is an ideal replacement for the old power supplies and are easily integrated into existing radio networks.
