DAM-D-72 AC Universal Ampermeter

General Informations

The device can be used in electrical panels, laboratories and test devices.With the assistance of a current transformer, it measures the AC currentpassing through the system in terms of Amper unite. Two over current set( SP1, SP2 ) with a different output contact for each.The first set value is SP2,the higher one is SP1. When the current exceeds the adjusted first over currentvalue (SP2) then the alarm1 led will start to blink and after the set delay time,the device would change the possition of the Re2 output contact.If the current exceeds the higher over current value the device opens its 1stoutput too. The current is called normal if it is below these two limits. Afterenergizing the device, “dA -d “ message appears on it’s screen for 2 secondsand then it starts to show the current value.Even when the power supply is off,the stored values will not be deleted.

■ When the measured value of the seconder current reaches 5,1 A, “ OvEr”
message starts to flash on the screen to warn the user that the value of the
current exceeded the limit values.
