Majortel DC Power Systems

Majortel DC Power systems (MTS) meet or exceed most equipment application requirements for today’s growing new technology networks.  The MTS system includes telecom grade switch-mode 48V rectifiers in a feature rich mounting shelf with integrated remote communication package. Each shelf is 1.75” tall, 11” deep and occupies a standard 19” wide rack space.




The Majortel dc Power system, MTS48/30BL-1U, is designed with a maximum of four, field-configurable, distribution circuits plus one battery circuit. Individual load bay slots are easily configured for on-site installation by choosing (before purchase) the required breakers in ratings of 5a, 10a, 15a, 20a or 30 amps. This circuit-breaker style of load distribution means that each system can support A/B enterprise server power requirements with or without battery back-up. Installation is made simple with the convenience of, included, standard NEMA line cord AC source connections. System capacity 1.74 kW.

Majortel Controller


The MTS-Com centralized man-to-machine interface is included with every system. The integrated controller monitors critical system conditions and facilitates system programming. The controller functions include fault alarms, alarm threshold adjustments, voltage adjustments and overall system status. This easy to read screen allows the user to program the unit with only a few buttons. The unit toggles audible alerts, LEDs and Form-C contact closures based on the system monitored parameters.
