DAM-B-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 passing through the system in terms of Amper unite. If the current exceeds the adjusted current then the alarm led started to blink after the the adjusted time delay changes the output position. When the current exceeds the adjusted current value the device starts to count for the adjusted delay time and after that, it opens its output contacts. After energizing the device, a “dA -b “ message appears on its screen for 2seconds and then it starts to show the current value.

■ The current transformer ratio can be adjusted between 5/5 and 10000/5 using the touch buttons on the front panel of the device.

■ Stores the maximum demand value and the peak value on its memory and keeps these values even if the energy supply goes off.

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