Power up your Defence with Stafix JVA Electric Fence Energiser: Jumbo Range

By 3 min read

combo

The JMB series is the most powerful and feature rich electric fence energiser JVA has manufactured to date. This continues JVA’s push for technical superiority in terms of Monitored Electric Fencing and IP Energisers®.

While the JMB energisers were specifically designed for game parks and exclusion fencing, they are also well suited to any large permanent electric fencing application.

The JMB series produces up to a remarkable 46 J of stored energy, currently the world’s largest battery powered energiser. A monitored electric fence reduces maintenance by reporting whenever there is a fault and by allowing you to check the fence from wherever you are using the Internet.

The JMB series introduces the JVA Virtual Keypad. This allows you to monitor, control and program the energiser from your Wi-Fi enabled smart device (phone, tablet, or laptop). The JMBs can also be controlled and monitored with a wired JVA 4-Line Keypad supplied with each unit.

Features

  • Combined electric fence energiser and monitor
  • Power or Loop Monitor depending on model
  • Virtual Keypad via your Wi-Fi enabled device (smartphone, laptop, or tablet)
  • Distant Fault Detection (DFD™) technology
  • High powered (up to 46 joules stored)
  • Mains or 12 V battery powered (mains via supplied 24 V plug pack)
  • Lightning protection on all fence connections
  • No mains inverter is required to run on solar and battery
  • Power on demand; it uses only the power it needs for the fence conditions
  • Able to be controlled and/or monitored through multiple options:
  1. 24/7 fence information available via GSM or Wi-Fi Virtual Keypad programming via a smart device
  2. Virtual Keypad using on-board Wi-Fi
  3. Cloud Router (requires a Cloud Router account and Gateway)
  4. Perimeter Patrol (requires a PC, TCP/IP Interface, and Perimeter Patrol Licence)
  5. Most JVA Z-Series Keypads (4-Line or touch screen keypad)
  6. Fence Line Remote Control
  • Built-in 1 A backup battery charger
  • 1 Siren and 2 Strobe 12 V outputs for standalone security installations (switched 12 V DC) On/Off switch
  • Programmable relays

By incorporating Power Monitoring and our patented, Distant Fault Detection (DFD™) technology, the JMB ZM1 and JMB ZM2 models can be configured to monitor long fences without the need to create loops or install return wires to connect the end of the fence voltage back to the energiser. This is also known as start of fence monitoring. For those who wish to use traditional end of fence monitoring, these models also have an optional fence return terminal.

JMB ZM1

The JMB ZM1 contains circuitry that allows it to power and monitor a single, high power fence zone. The Power Monitor measures both the real and reactive components of the fence voltage and feed current. By doing so, it can detect a fault at distances beyond 10 km from the energiser.

Features

  • Up to 46 joules (stored) for better performance on long fences
  • Measures feed, return and the ground voltage
  • Measures real and reactive feed currents to distinguish real faults from capacitive fence currents
  • The JMB ZM1 contains our patented Power Monitor with Distant Fault Detection (DFD™)

JMB ZM2

The JMB ZM2 contains circuitry 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.

Features

  • Two independent fence zones each with up to 23 J (stored)
  • Synchronized outputs can be bridged for 46 J (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

JMB ZM50

The JMB ZM50 contains our patented Loop Monitor with Distant Fault Detection (DFD™). The loop or loops of live wires may run down and back on the same fence or all the way around a property. While previous fence loop monitors suffered from a range limitation of approximately 10 km of fence or 30 km of wire, DFD™ has greatly increased this range.

Features

  • Can split a single fence into up to 50 sectors
  • Can report the position of a fault as a percentage of overall fence length
  • Short sectors can be accurately defined using JVA sector dividers
  • ELV (Extra Low Voltage) open circuit detection
