DC Ammeter Shunt
Our ADS-S shunts are 50mV rated. They are compatible with every other 50mV input ammeter... and are used with our AM60-A. The accuracy of our shunts is better than +/- 1/4% of the rated value. By definition, a shunt is a resistor, and will generate heat with passage of current. Because of this, the resistance blades of the shunt should be mounted in a vertical position to promote a free convectional flow of air. Where this mounting position is impractical, or where the shunt may be located in a small confined area, force cooling air may wish to be considered. Locations near your battery installation, and outside the cabin or engine compartment are best. Additional consideration should be given as to the protection from physical damage and any short circuiy potential near by. A good rule of thumb when sizing a shunt for your anticipated electrical load, is to limit proposed max amperage loads to approximately 66% of the shunt's rated value. For example... using the 85A shunt.... you should be planning a design load of around 56-60 amps max.... and approximately 100 amps using the ADS-S150A shunt. shunts should be installed in the negative, or grounded side conductor.
