The Ammeters are compact, microcontroller based instruments and are supplied with a separate CT of 40 Ampere AC current signal. The instrument may be calibrated as desired and a CT of the required AC primary current will be supplied. The current is indicated on a 4-digit seven-segment LED display and the instrument operates on universal AC power of 90 to 270 VAC, 50/60 Hz.

The DAX series instruments are a versatile range of low cost instruments that provide total AC current indication that is being drawn into the rack or panel. They may be mounted inside the PDU and wired easily to the current source. A Sticker is also provided for external panel mounting as an accessory.
