This device is rated to protect against EMP, ESD, and CME damage. The EMP Defender works like a flood control gate on a lake. On a lake once the water level reaches a maximum level the extra water is diverted and the lake level is maintained at a safe level. The EMP Defender works like this by shunting the extra voltage away from your electrical circuit allowing it to operate as normal.

FAQ
What is the MEMP12VSAE mainly used for?
The MEMP12VSAE is designed to help protect 12VDC battery-powered electrical systems from damaging surge events. Its primary application is vehicle protection, but it can also be used on compatible 12VDC battery circuits in marine, RV, powersports, generator, emergency power, communications, and other low-voltage DC applications.
How is the MEMP12VSAE different from the MEMP12V?
The MEMP12V and MEMP12VSAE are designed for similar 12VDC protection applications. The main difference is the connection style. The MEMP12V uses wires with ring terminals for direct battery connection, while the MEMP12VSAE uses an SAE-style two-pin connector for quick connection and disconnection.
What is the SAE connector used for?
The SAE-style two-pin connector allows the MEMP12VSAE to be quickly plugged in or disconnected from a compatible 12VDC battery circuit. This style of connector is commonly used with small battery chargers, trickle chargers, battery maintainers, motorcycles, powersports vehicles, and other 12VDC battery accessories.
What voltage is the MEMP12VSAE designed for?
The MEMP12VSAE is designed for 12VDC electrical systems only. Do not use this device on AC power, 24VDC systems, or any voltage outside the product rating.
What does the 150KA rating mean?
The 150KA rating refers to the surge current capacity of the device. The MEMP12VSAE is designed to help protect compatible 12VDC electrical systems from damaging surge events when properly connected.
Does the MEMP12VSAE protect against EMP, CME, solar flare, and lightning-related surges?
Yes. The MEMP12VSAE is designed to help protect compatible 12VDC systems against normal surge events, indirect lightning-related surge activity, and EM-related surge events such as EMP, CME, and solar flare related electrical disturbances.
Where should the MEMP12VSAE be connected?
The MEMP12VSAE should be connected to a compatible 12VDC SAE-style battery connection. For best protection, the SAE lead should be connected as close to the battery as practical. If direct battery connection is not possible, it may be connected to another suitable section of the 12VDC electrical circuit.
Can the MEMP12VSAE be used with a battery tender or trickle charger connection?
Yes. The MEMP12VSAE is designed for use with compatible SAE-style 12VDC battery connections like those commonly used with small battery chargers, trickle chargers, and battery maintainers.
Can the MEMP12VSAE protect both a battery charger and the vehicle?
Yes. When used with a compatible SAE-style T-connector, the MEMP12VSAE can be connected in a way that helps provide surge protection for the battery charger and the vehicle or equipment electrical system the charger is maintaining.
Can the MEMP12VSAE be used on vehicles?
Yes. Vehicles are a primary application for the MEMP12VSAE. It can be used on compatible 12VDC vehicle battery circuits with an SAE-style connector to help protect the vehicle’s electrical system from damaging surge events.
Can the MEMP12VSAE be used on motorcycles, ATVs, UTVs, boats, RVs, or generators?
Yes. The MEMP12VSAE may be used on compatible 12VDC battery circuits in motorcycles, ATVs, UTVs, boats, RVs, generators, off-grid systems, communications equipment, and emergency equipment when the system uses a compatible SAE-style connector and matches the product rating.
How is the MEMP12VSAE wired?
The MEMP12VSAE uses an SAE-style two-pin connector instead of ring terminals. The SAE connection must be wired with the correct polarity for the 12VDC system being protected.
Is polarity important when using the MEMP12VSAE?
Yes. The MEMP12VSAE is polarized. Always verify SAE connector polarity before connecting the device. Incorrect polarity can damage the surge protector or connected equipment.
Does the MEMP12VSAE connect to chassis ground?
No. The MEMP12VSAE connects through the positive and negative sides of the 12VDC electrical circuit using the SAE-style connector. On a vehicle, the chassis is already connected to the negative battery terminal. Adding a separate chassis ground connection could create a ground loop and cause electrical issues.
What do the blinking red eyes mean?
The red eyes on the MEMP12VSAE blink when the device is connected correctly and functioning properly.
Does the MEMP12VSAE need a fuse or circuit breaker?
No additional fuse or circuit breaker is required specifically for the MEMP12VSAE because it connects in parallel with the electrical circuit and includes built-in overcurrent protection. Always make sure the vehicle or 12VDC electrical system has proper circuit protection for the overall installation.
Can the MEMP12VSAE be installed outdoors?
The MEMP12VSAE is waterproof and suitable for harsh environments, but it should not be submerged in water. Install it in a secure location where it will not be exposed to physical damage, improper use, or connector damage.
Can the MEMP12VSAE be submerged in water?
No. Do not submerge the MEMP12VSAE in water. Although the device is waterproof, it should be installed and used in a way that prevents submersion or damage to the SAE connector.
Can the MEMP12VSAE be used on AC power?
No. The MEMP12VSAE is for 12VDC electrical systems only. Do not use this device on AC power.
Can the MEMP12VSAE be used on 24VDC systems?
No. The MEMP12VSAE is designed for 12VDC systems only. Do not use it on 24VDC systems or any voltage outside the product rating.
Can the MEMP12VSAE be opened or modified?
No. Do not open, modify, tamper with, or improperly use the MEMP12VSAE. If the device is damaged, improperly connected, or no longer indicates proper operation, it should be replaced.
Who should install or use this product?
This product should be used by someone familiar with 12VDC electrical systems, SAE-style battery connectors, polarity, and the equipment being protected. When in doubt, consult a qualified technician, mechanic, marine technician, RV technician, or installer.
Does this product include a warranty?
Bad Wolf surge protection devices include a 5-year product warranty. Eligible products may also include connected equipment warranty coverage when properly installed and registered according to the warranty terms.
