Redler Technologies has released a detailed white paper highlighting the fundamental limitations of mechanical relays in -48V telecom power systems and outlining the advantages of its Power Rider solid-state electronic circuit breaker technology.
The paper by Shaya Redler explains that mechanical relays suffer from inherent design flaws, most critically electrical arcing and sparking during contact opening and closing under load. In DC telecom environments, where there is no natural zero-crossing point to extinguish arcs, this effect is particularly severe, leading to intense heat, electromagnetic interference (EMI), and accelerated contact degradation.
According to Redler Technologies, arcing can generate temperatures exceeding 5,000 K, producing broadband EMI and RFI capable of disrupting sensitive telecommunications equipment. Over time, relays also experience rising contact resistance due to oxidation, corrosion, fretting, material erosion, and contamination, which results in higher power losses, thermal stress, and reduced reliability. These issues are compounded by thermal management limitations, contact welding risks, and the finite mechanical lifespan of relay components.
The Power Rider electronic circuit breaker addresses these challenges by eliminating mechanical contacts entirely. Using semiconductor-based switching, it removes arcing, contact wear, and EMI generation, while delivering ultra-fast fault protection with response times as low as 300 nanoseconds. The system also incorporates advanced thermal management, bidirectional current blocking, and intelligent networking capabilities for coordinated power management. As a result, Power Rider offers significantly higher reliability, longer operational life, and improved protection for modern telecom power infrastructures compared to conventional mechanical relay solutions.
