3 .1 .2 JMBx-ZM2
The JMBx-ZM2 contains our patented power monitoring with Distant Fault
Detection (DFD™). The Power monitor measures both the real and reactive
components of the fence feed current. By doing so, it can detect a fault at
distances beyond 10km from the energizer. The JMBx-ZM2 contains cir
-
cuitry that allows it to power two separate fences. Each fence has its own
Power monitor and optional fence return terminal for end of fence voltage
monitoring.
• Two independent fence zones each with up to 23 Joules (stored)
• Synchronised outputs can be bridged for up to 46J (stored) into one
fence
• Measures both zones Feed and Return and the Ground voltage
• Measures real and reactive Feed currents to distinguish real faults from
capacitive fence currents
