Cape Town Electric Fencing and Automation. Africa Electric Fencing is an SABS certified installer: Our policy is “do it right the first time”. This means fewer problems for the customer and ultimately less upkeep or additional expenses after the electric fence has been installed. A quality check is done after each successful instillation.

SECURITY ENERGIZERS

We at AFRICA ELECTRIC are proud to say that we only use SABS and International safety grade energizers like the JVA or STAFIX range of energizers.

Z-RANGE
The imported JVA Z-Range of energisers is designed to be the best affordable high-feature security energiser in the world. It was built and designed as a product of over 30 years of electric fence experience earned in the most testing international environments. The unit has a unique LCD voltage display so that the fence output and return voltages can be seen clearly.
The unit can be operated by key-switch or by the optional LCD keypad.
FEATURES INCLUDE
 LCD voltage display
 Powerful 4 joules peak output energy
 Designed to pass IEC60335.2.76 and EMC standards (reports available on request)
 Wall mountable, robust enclosure with detachable PCB chassis for ease of installation and repair
 Earth monitor input
 Gate input
 Key-switch
 Keypad programmable
 Lower-power mode
 Entry/Exit delay from gate input trigger
 Switched +12V outputs for Siren and Strobe up to 30 Watts for 3 minutes
 Microprocessor controlled
 Outputs may be wired for All-Live wire fences (All-Live model only)

WHAT IS BI-POLAR FENCING?
The new JVA Z14A Electric Fence Security Energisers can be operated in bi-polar mode. This gives rise to the questions: What is bi-polar and what exactly are the benefits of this wiring configuration?
A bi-polar fence is an all-live wire fence. A bi-polar energiser has the ability to pulse synchronized positive and negative pulses down alternative wires of the same fence line. So, instead of having alternative live and earth wires on the fence line, one now has one wire with a positive pulse and one wire with a negative pulse. This means that all the wires on the security fence are live (with the exception of one true earth wire in the fence grid).
A reading taken between the positive pulsing or negative pulsing live wires and the true earth, will give half the voltage of a normal live earth configuration. However, when one touches both the positive and negative pulsing wires, one will receive the ‘full Monty’. The big plus factor of this configuration is that, by reducing the voltages to each wire, one eliminates the annoying and often difficult-to-eliminate arcing experienced in coastal or dusty areas.
