Featuring heavy-duty 8 AWG wiring and a smart LED status indicator, this compact, military-grade device ensures your electrical system stays resilient against the harshest surges.

## Description

Product description Max EMP Defender 12V Gen 2 Designed with our Exclusive Overwatch protection circuitry that provides ultra-fast surge response and easy to read status indication. The SPD is built to handle surge currents up to 500,000 Amps (500kA). Designed using Metal Oxide Varistors (MOV), Transient Voltage Suppression (TVS) Diodes and Gas Discharge Tube (GDT) technology. With reaction speeds in the trillionth of a second and capable of surviving thousands of repetitive surges when we say this device is built tough that is an understatement. By using Military and Commercial grade components this SPD is designed to protect against every type of transient surge possible including EMP all phases, CME (coronal mass ejection), Solar Flare, Lightning and more... Bad Wolf is a leader in high power surge protection devices SPDs and provides one of the largest selections of both AC or DC available. Bad Wolf is a Service-Disabled Veteran Owned Made in the USA company that is not only a contract manufacturer for private and federal agencies, but also backed by the SBA (small business administration) to provide custom solutions for consumer applications as well. Vehicle Protection ATV, UTV and Off-Road Vehicle Protection RV Protection Marine Protection Compact Design Measuring 5.5"W X 3.25" W X 2" H the Max EMP Defender 12V fits most mounting locations Status Indicator Overwatch Protection Circuit With Smart Status Indicator Green Means All OK, Red Indicates There Has Been A Surge And No Light Means No Power Applied Flush mount design Unique 3 stage surge protection with reverse polarity surge protection with Response times in the trillionth of a second. Heavy duty wire The Max EMP Defender 12V comes with 3 feet of 8 AWG wire and uses soldered (Not Crimped) 3/8" stud ring terminals. Types of surges Defective alternator Poor electrical connections CME (Solar Flare) Battery Jumpstart EMP (E1,E2 and E3 Phases) ISO 7637-2 MIL-STD (188,461,464,RS105,CS115-117) ITU-T K.12 IEEE C62.31 IEC 61643-311 GDT UL 1449 Sources of electrical surges The most common source of vehicle electrical surges results from a faulty alternator. The next most common surge is due to ESD Electrostatic Discharge and electromagnetic induced coupling. Construction Built using the latest technology components that are fast, powerful, and rugged. Using a combination of TVS Diodes, MOVs and GDTs this surge protector has reaction speeds in the trillionth of a second and is capable of up to 500,000 amps of surge suppression. Old style TVSS surge protectors incorporated a separate green ground wire, this often resulted in what is called a "ground loop". This ground loop can cause damage to the electrical system and at least create noise, this problem was only exacerbated at high delta V. Technical Specifications

Review: easy to install - the perfect item to protect your car/truck
Review: Very easy to install. - I got this for my motorhome. It's easy to install, just attach it across the battery. I installed this one in the house section. The cables are high quality and very beefy to they'll take the surge. I took a peek inside the box to make sure there's actually something in there. I only saw the back of the PCB and couldn't get into it further without risking destroying it, so I didn't see much. I was not surprised at all though to find that it actually does appear to be a surge suppressor, not just a box with an LED. These work by shunting current when there's a voltage spike- and from what I saw it looks like that's exactly what it will do. Until this actually saves, or fails to save, my motorhome from a spike, it's impossible to know how well it does the job. Surge suppressors are never a guarantee, but having a surge suppressor like this on the 12V side is something I am very glad to have in place. They are not cheap, but it's cheaper than losing the motorhome. I would consider installing one in the vehicle engine as well.

### ⭐⭐⭐⭐⭐ Peace of mind during a time of increased solar activity!
*by A***. on May 23, 2024*

At the time of this review, there have been multiple solar flares causes by a massive geomagnetic storm on the surface of the sun that has been producing multiple "M" and "X" type of coronal mass ejections (CME). These are very bad for electronics. In fact, they can wipe out every electronic that is on at the time of an electromagnetic pulse. Having this EMP protection device gives me peace of mind in case we are affected by the solar flares and other sources of EMPs. The only other option is a Faraday Cage. But those are expensive and usually built on a smaller scale.
