Power & Utility Systems in the Majortel Product Line

Majortel Power Systems meet or exceed equipment application requirements for today’s growing new technology networks.  The utility systems include telecom grade switch-mode rectifiers or high-frequency isolated dc/dc converters in a feature rich mounting shelf with integrated remote communication package. The comprehensive system package integrates control, communication, power and distribution. Existing deployments are approved for substation auxiliary dc power systems.

The Majortel dc Power system, MTS130/20AT-1U, is designed with a maximum of 2800W using two (2) power modules, communication module and integrated distribution circuit breaker.

Each system is designed to occupy a true 1U (1.75″ tall) rack space in a standard 19″ wide rack and under 11″ deep. Installations can include one or two compact, high density and reliable switch-mode rectifiers at 10 amps each for a total system capacity output configuration of 2800W @ 140Vdc.

The integrated system includes a simple 2-pole output breaker configuration suitable for connections to an existing bus, individual load or battery storage.


130V Power System

Ordering Assembly Number:
MTS130/20AT-1U: rack system with 19″ ears, controller and 2 rectifiers (20A)


130V to 48V DC/DC Converter

Ordering Assembly Number:
MTD48/50-130-1U: rack system with 19″ ears, controller and 2 converter power modules (50A)

The Majortel dc/dc Converter system is a sleek, compact design that is ideal for applications requiring 48V dc power from a 125-130V dc power source. Each MTD48/50-130-1U system is designed to occupy a true 1U (1.75” tall) rack space in a standard 19” wide rack and under 11”deep. Typical installations include two compact, high density and reliable high frequency 25 amp converters, for a total system capacity configuration of 2900W @ 58Vdc output.

The MTD48/50-130-1U converter system includes a simple Load 1 and Load 2 breaker distribution to support multiple isolated output circuit configurations and the MTS-Com centralized man-to-machine interface. The system power capacity is user configurable for 50A applications. The dc-dc converter modules are hot-swap capable, facilitating field replacement in a matter of minutes. Install or two modules with automatic load sharing.
