JVA High Voltage Monitor & Energizer

The JMB series is the most powerful and feature-rich high-security fencing energizer JVA has manufactured to date. It continues JVA's reputation of technical superiority in the area of monitored electric fencing and IP Energizers®.


The powerful JMB series produces up to 46J of stored energy, which currently makes it the world’s largest battery-powered energizer. While these energizers were originally designed for game parks and exclusion fencing, they’re extremely well suited to any large permanent electric fencing application.

Reduced maintenance

This monitored electric security fencing solution reduces maintenance and saves you time with its electric fence fault finder, which allows you to check the fence from wherever you are in the world. With our easy-to-use JVA virtual keypad, you can monitor, control, and program the fence energizer from your Wi-Fi enabled smart device (phone, tablet, or laptop). The JMB series can also be controlled and monitored with the wired JVA 4-Line keypad controller that is supplied with the unit.
