SP-MBUS-40V-L
Combined coarse and fine surge protection for M-Bus networks
Application
The surge protection is designed to protect a two wire communication line of an M-Bus network against impulse overvoltage. The two stage protection protects M-Bus devices against overvoltage between the wires and between the ground and each wire. The surge protection is suitable for M-Bus slave and master devices regardless of type.
Main characteristics
- Maximum current load 0.4A – 255 M-Bus devices.
- Maximum M-Bus operating voltage 44V.
- Peak surge current In(8/20μs) 10kA.
- Serial resistance per line 2.2 Ω.
- Plastic box with a width of just 17.5mm.
Guarantee of quality
- In order to achieve maximum possible level of reliability and quality the devices are electrically tested and pass visual inspection during manufacturing.
