140 mile 110 V Energizer

STX-M20R 110V Energizer

Stafix Energizer M20R

Remote control capable. Delivers maximum power and reliable performance for your permanent electric fencing.

Powers up to 140 miles (1,400 acres) of fence
22 J maximum output energy (34 J stored energy)

bg-key-tech-cyclic-wave-technologyCyclic Wave™ technology.  Provides a clean, powerful pulse that maximizes the energy that travels down the fence line, resulting in continuous power right to the end of your fence for optimal livestock control


bg-key-tech-bi-polar-technologyBi-polar technology.  Enables the user to power a fence system to perform exceptionally well in dry, low conductive soil


bg-key-tech-remote-control-capableRemote capable.  Using a Stafix fence remote (with remote capable Stafix energizers) enables you to switch the energizer on or off from anywhere along the fence line. This makes it easy to manage repairs and maintenance


bg-key-tech-indicator-lightsIndicator lights.  Easy to read light bar display provides an instant measure of the energizer output voltage for quick fence diagnostics. The LED display shows red when heavily loaded


bg-key-tech-large-terminalsLarge terminals.  Mounted on the front of the energizer casing for convenience, these large terminals are easily adjusted and accept up to two fence wires. The slotted terminals make inserting wires and getting a good connection easy


Low impedance.  Designed to deliver power to the end of the fence even under heavy load e.g. foliage, undergrowth

bg-key-tech-low-interferenceLow interference.  Cyclic Wave™ technology delivers outstanding fence performance and helps to minimize electromagnetic interference in line with international EMC standards


bg-key-tech-rugged-compact-designRugged design.  Hi-tech components and advanced research and development have enabled us to make powerful energizers in a rugged, compact, polymer case


Half voltage terminal.  Up to 4,750 V output



2 year (includes lightning) Warranty
