General description
Smart Power Module System (SPMS) is a modular system for powering Power over Ethernet devices with different pin out.
Each module performs its function independently and guarantees maximum reliability and protection.
The products that make up this solution are:
•
SPI: Surge Protector Injector
•
SPP: Surge Protector Passthrough
SPI
Surge Protector Injector is a Power over Ethernet injector with integrated arresters, reverse polarity protection, redundant
power supply and selectable pin out and polarity.
Each SPI can be configured to handle a different type of PoE injection map. The configuration of the power pin out is simple
and does not require any computer skills: just select the mode and polarity with the microswitches on the side of the SPI
module.
