FAQ
What is the MEMP12V mainly used for?
The MEMP12V 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, generator, emergency power, communications, and other low-voltage DC applications.
What voltage is the MEMP12V designed for?
The MEMP12V 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 MEMP12V is designed to help protect compatible 12VDC electrical systems from damaging surge events when properly installed.
Does the MEMP12V protect against EMP, CME, solar flare, and lightning-related surges?
Yes. The MEMP12V 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 MEMP12V be installed?
The MEMP12V is recommended to be connected directly to the battery terminals for best protection. If battery installation is not possible, it may be connected to another suitable section of the 12VDC electrical circuit.
Can the MEMP12V be used on vehicles?
Yes. Vehicles are the primary application for the MEMP12V. It is designed to connect to a compatible 12VDC vehicle battery circuit to help protect the vehicle’s electrical system from damaging surge events.
Can the MEMP12V be used on boats, RVs, generators, or other 12VDC battery systems?
Yes. The MEMP12V may be used on compatible 12VDC battery circuits in marine, RV, generator, off-grid, communications, and emergency equipment applications when installed according to the product instructions and voltage rating.
How is the MEMP12V wired?
The MEMP12V has two wires. The red wire connects to the positive side of the 12VDC circuit, and the black wire connects to the negative side of the 12VDC circuit.
Does the MEMP12V connect to chassis ground?
No. The MEMP12V connects only to the positive and negative sides of the 12VDC electrical circuit. On a vehicle, the chassis is already connected to the negative battery terminal. Adding a third chassis ground wire could create a ground loop and cause electrical issues.
Is polarity important when installing the MEMP12V?
Yes. The MEMP12V is polarized. The red wire must be connected to positive, and the black wire must be connected to negative. Always verify polarity before connecting or energizing the circuit.
What do the blinking red eyes mean?
The red eyes on the MEMP12V blink when the device is connected correctly and functioning properly.
Does the MEMP12V need a fuse or circuit breaker?
No additional fuse or circuit breaker is required specifically for the MEMP12V 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 MEMP12V be installed outdoors?
The MEMP12V 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 or improper use.
Can the MEMP12V be submerged in water?
No. Do not submerge the MEMP12V in water. Although the device is waterproof, it should be installed and used in a way that prevents submersion or damage.
Can the MEMP12V be used on AC power?
No. The MEMP12V is for 12VDC electrical systems only. Do not use this device on AC power.
Can the MEMP12V be used on 24VDC systems?
No. The MEMP12V is designed for 12VDC systems only. Do not use it on 24VDC systems or any voltage outside the product rating.
Can the MEMP12V be opened or modified?
No. Do not open, modify, tamper with, or improperly use the MEMP12V. If the device is damaged, improperly connected, or no longer indicates proper operation, it should be replaced.
Who should install this product?
This product should be installed by someone familiar with 12VDC electrical systems, vehicle batteries, 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.
