RPM - Redundant Power Module - Dual Output      

Redundant Power Module

While modern power supplies are sophisticated designs with superlative performance, they remain the device with the shortest MTBF.  To mitigate this threat, Orbital Research introduces the RPM (Redundant Power Module) to provide one for one (1:1) DC power redundancy.  This simple, low cost module provides an extremely reliable passive method of providing automatic backup power for the majority of satellite system devices.  It has two inputs, one for each power supply, and simply takes the power supply with the higher voltage.  So, if one power supply fails, the RPM automatically switches to the other supply. 

The RPM also has dual outputs, so that you can supply two separate devices, such as a BUC/LNB combo in a VSAT, or both polarities for LNBs.  Since the RPM uses our standard SIP chassis, it integrates easily into stacks, plates, or rack-mountable chassis with our other modules.

RPM or RPT?

The Orbital Redundant Power Module provides DC in DC out redundancy only, while the Redundant Power Tee provides for redundant power insertion into the L band signal.

Attention:

The RPM does not sum the two input power supplies to produce a combined output; only one Power Supply is supplying current at any given time.

Redundant Power Supplies

The first step in Redundancy, is to protect against the most common cause of failure - loss of power.  The Redundant Power Module automatically switches to the second power supply in case of failure.  The power supplies are hot-swappable, making the RPM the least expensive redundancy devise for your system.

Modems and receivers often cut costs in the design of their power supplies.  LNBs, especially external reference units can put too much of a load on a cheap power supply, causing premature failure.  By taking the powering function away from modems and receivers, the user can add the quality and margin needed in the power supply for reliable and consistent system operation.

As well, powering the BUC or LNB independently makes for much easier splitting or combining of L band signals, and keeps the system fully on while adding or removing modems.
