Thunderbird 350km Energiser for the Biggest Properties Out There
If you're running a large cattle or sheep operation and need an energiser that doesn't flinch, the Thunderbird MB-5600R is the top of the range. With 55.3 stored joules and the ability to cover up to 350km of fence line, this is as serious as it gets for mains or battery powered energisers. Both a 12V lead and AC adapter come included, so you're set up and running from day one.
A Thunderbird 350km Energiser That Goes Where the Power Doesn't
For those remote paddocks where mains power just isn't an option, the MB-5600R pairs with an optional solar kit compatible with a 480-watt panel, the largest solar option across the whole Thunderbird range. Hook it up to your external battery and keep the fence hot without needing a power source nearby. It's a proper off-grid setup for properties that need it.
Know Exactly What Your Fence is Doing at All Times
The digital display on the MB-5600R puts everything in front of you at once, output voltage, earth condition, joules, and amps, all on the same screen without any toggling required. When you're managing this much fence line, being able to read the situation quickly matters.
The built-in earth monitor keeps a continuous check on your earth system condition so you're not left chasing a fault across the property when something doesn't look right.
Your Thunderbird 350km Energiser Responds Before You Even Notice a Problem
The auto power boost function monitors your fence and increases the energy output automatically when conditions demand it. Whether it's a heavy weed load or a change in conditions, the unit responds on its own. You've got three power levels to choose from (low, medium, and high, up to 9.9kV) and 13 pulse speed settings ranging from 1.2 to 2.4 seconds to fine tune performance for your setup.
The built-in alarm will trigger the internal buzzer the moment fence voltage drops below your set threshold, which you can dial in anywhere between 2 and 6kV. You'll know there's a problem well before the stock figure it out.
Tough Enough to Live Outside Year Round
The MB-5600R is sealed with an O-ring enclosure built to keep out dust and moisture no matter what conditions it's sitting in. This is a unit designed to work hard in the field, not one that needs to be looked after.
Control Your Thunderbird 350km Energiser From a Distance
The MB-5600R is remote ready, and with the optional ERC-2 remote you can turn the unit on or off and check the voltage digitally without walking out to it. With a no-load voltage of 8.9kV and 7.9kV at 100 ohms, you're getting strong output right across that 350km reach.
When the battery starts to run low, the auto battery save function steps in automatically. It drops the output to low and pushes the pulse rate to maximum to squeeze every bit of life out of the remaining charge, keeping your fence running as long as possible before you need to recharge.
