Remote AC or DC Isolated Powering
The Positron Power Isolator provides a high-voltage isolated source of 24Vdc or 48Vdc
This technology allows companies to safely bring either floating 120Vac or floating Station Battery 129 Vdc or 48 Vdc power to any point in a substation, irrespective of the local ground potential. It consists of a matching input power unit and an output power unit each with a 50 kV rms isolation barrier. A high dielectric strength cable between the matched power units delivers floating isolated power via the output power unit.
The latest in high-voltage isolation and power electronics, Positron’s Power Isolator system provides a source of isolated power to power remote devices.
Some Applications to power remote devices
- GPON Fiber-Fiber Junction (FFJ)
- Copper Fiber Junction (CFJ) inside or outside of the substation Zone of Influence (ZOI)
- A substation’s wireless receiver in the switchyard
- Surveillance cameras
- Alarm systems
- Lighting
It can also be used for lightning protection in other applications like safety powering remote speakers in an outdoor concert environment. Positron’s Power Isolator technology provides a source of power free from any remote ground reference. This results a power source immune to sudden high-voltage surges.
Housed in two 12” x 14” x 6” NEMA 4X rated fibreglass closures, each closure contains sophisticated power conversion electronics partnered with Positron’s unique high-voltage isolation transformers, can be separated by thousands of feet of 18AWG copper conductors.
Isolation of 50kVrms (continuous) is achieved when the 18 AWG electrical conductors are isolated by the system’s high-voltage isolation transformers. The 18 AWG conductors should be contained in Schedule 80 PVC conduit between the Power Isolator’s input and output units to achieve the highest level of high-voltage isolation. The Power Input and Power Output Units can be separated from 3 feet to more than 2000 feet.
The Positron Power Isolator Series 100 can deliver an output of 100W @ 48Vdc that is fully isolated from any high-voltage or remote ground influence. Powered from a source of either 120Vac or floating 48Vdc / 129Vdc from a substation battery, you can bring 100W @ 48Vdc output power to any point, irrespective of the local ground potential.
The standard Power Isolator Series 100 is suitable to provide isolated power to a Copper Fiber Junction (CFJ) of a hybrid-fiber high-voltage communications isolation installation, or an all-dielectric Fiber-Fiber Junction (FFI) either located inside or outside of the Zone of Influence of a power station. Other models are customizable and available for higher power outputs (200W, 300W, etc.). with different input voltages and providing different output voltages, regulated or unregulated power.
