400 Amp Meter Base With 2 200 Amp Disconnects

A 400 amp meter is a valuable asset for any electronics or appliance repair technician. If you are reading this, chances are that you have a product that needs to be tested and an amplifier or amp converter that you would like to use to accurately test it before attempting to fix it. Many people will simply purchase the most expensive meter or amp converter on the market without considering whether or not it will actually work as it should. This article briefly discusses a few things about the two styles of meters available:

A four wire system is probably the most common style of circuit testers or meter that is found in homes. There are a variety of different manufacturers that make this style including K&N, Mitel, Belgers and Honeywell. The two 200 amp meter consists of two wires that connect the diode to the preamplifier. One wire connects ground to the negative side of the diode and the other wire connects the positive charge to the positive terminal on the preamplifier.

The four wire system works great, but two 200 amp meters that are wired in tandem can give you more accurate measurements. This option is becoming more popular since the newer models have much longer cables and they are often manufactured in bulk. Two separate four-wires usually connect the preamp to the chassis and the amp to the amplifier. These two types of products are also available with dual triodes and single diodes.

A three wire system is another option for a 400 amp meter base with two 200 amp disconnects. This system will give the ability to read both amp controls at the same time and will give accurate measurements if each amp control is not set specifically. Some manufacturers may even have their own proprietary indicators for various amp controls. These are most commonly found on multiples or pentode meter bases. If you find one, make sure to inquire about its connection as there are variations in the wiring used.

An eight wire base with two 200 amp meter disconnects is another type of solution. These units are very popular because of their simplicity and ease of installation. The only challenge is compatibility between some devices such as the amplifiers and monitors. You may need an adapter or splice to make this work.

There are some options for this system. One option is to use a separate device for input and output. For instance, you could use an RCA cable for input and use some type of interface device or speaker connectors for output. A separate amp could also be installed as well. Many signal conditioning systems are also equipped with separate line input and output jacks.

You should take note that amp meters can be sensitive to certain levels of amp power. So you should never connect your device to an amp that is over rated. If you are using an amp without a meter, the device may get overloaded and give incorrect results. This can be a safety issue for you and your equipment.

Finally, an amp meter with a two 200 amp meter detachment can help you monitor input/output busses. If you run an AMP system, the two separate earth shields on the amp meter will give you protection from overloads as well as protect against switching power sources. You will always have continuity protection between the earth shields anyway. So, you really don’t lose anything by having this attachment. This type of base with two 200 amp meter detachment is a great piece of equipment to add to your inventory.
