La Marche TPM Modular Rectifier

The La Marche TPM (Total Power Module) Switchmode Rectifier Systems are compact self contained Power Systems that provide the Modular Power that today’s Telecommunications, Process Control and Utility Substation applications require. The TPM Switchmode Rectifer is the building block of these reliable systems utilizing advanced switching technology. Its filtered output provides the clean power required for sensitive loads. The TPM is rated at 750 watts and available in 24V (30 amps) and 48V (15 amps) versions. A 12V TPM module is also offered and rated at 375 watts (30 amps). The Rectifier modules are hotswappable plug-in type. Replacement is swift and simple, and achieved without affecting the integrity of the system.

The universal input voltage range of 102-264VAC and frequency of 47-63Hz is ideal for power demands throughout the world. The AC input and DC output wiring of the Rectifiers can be done either in pairs from the same side of the cage or as a complete system. A convenient AC input cord (6 ft long, 20A rated) is supplied to power each pair of TPMs Rectifiers per cage. The DC output wiring is done by hardwiring to the provided busbar. Flexibility is given to hardwire a single connection for all Rectifiers or for each pair of Rectifiers per cage. This allows for custom field installations and gives greater system flexibility to suit the customer needs and preferences. TPM Systems are factory configured with one to four Modules in a single Cage. Distribution Modules consisting of either GMT Fuses or Breakers can share a Cage with the Rectifiers to form a complete Power System.
