What is Motorola 2005 R56?
Motorola 2005 R56 (68P81089E50B), Standards and Guidelines for Communications Sites details Motorola’s requirements for the installation and performance of communications equipment, infrastructure and facilities. As opposed to other specifications, Motorola R56 is an all-encompassing specification, covering the entire shelter from site planning to system turn up.
Motorola’s 2005 R56 standard is known throughout the industry as the most complete and stringent specification for protection of mission critical communications equipment at today’s advanced public safety and commercial wireless communications sites. It is the standard to meet as of March 2007.
What Changed in the 2005 Revision?
Although revisions to most chapters were made to reflect recent changes to industry standards, the SPD chapter of the 2005 revision of Motorola R56 places stringent new performance requirements on AC surge protectors. The 2005 R56 requires Motorola approved and witnessed laboratory testing, demonstrating low let-through voltage and high maximum surge capability without protector degradation. This replaces the previous R56 requirements, which were based on the joule (energy) ratings of the individual MOV and SAD modules and did not require system level testing. With the 2005 revisions, hybrid MOV/SAD protectors must be coordinated to withstand electrical surges up to 160 kA 8/20 µs without damage to the SAD component, while still providing the benefit of low SAD let-through voltages. This results in superior reliability and increased suppressor life. Prior to the 2005 R56 Standard, there were no protectors on the market that could simultaneously meet both these requirements. ACData is the first to deliver an MOV/SAD hybrid that does.
The ACData Solution.
Motorola’s 2005 R56 requirements have raised the bar, challenging the industry to develop new technologies. ACData Solutions’ engineers have stepped up, developing a new patent-pending Advanced Coordinated Hybrid ™ technology that seamlessly combines the high surge current capability of MOVs with the low let-through voltage of SADs. This new technology meets Motorola’s revised 2005 R56 standard and has resulted in the most reliable and best performing advanced AC protection solution on the market. ACData’s engineers have developed a new technology to ensure our surge protection products meet Motorola’s stringent 2005 R56 requirements, greatly enhancing performance and reliability. We are the first manufacturer to meet the new requirements, gain official Motorola R56:2005 approval, and begin delivery of products.
Your Bottom Line.
Motorola has revised the R56 chapter covering SPD’s, eliminating joule ratings and replacing them with stringent requirements for laboratory proven MOV/SAD coordination, resulting in high surge current withstand and low let through voltages. To meet the 2005 R56 challenge requires that manufacturers develop durable products using new technologies.
