What is the ATT2 Module?
PQube® 3 add-on module for high voltage DC monitoring
The ATT2 module is an optional add-on to your PQube® 3. This module allows you to measure and
record one DC voltage, one DC current, and DC power for your high voltage DC application.
You need to use an ATT2 module if the DC voltage level exceed the PQube3 analog input rating
(Analog channel max range is 100 VDC).
A typical use of the ATT2 module is for PV (Photovoltaic) generation, UPS battery bank monitoring,
VFD DC bus monitoring and more…
This module utilizes 2 Analog input channels on your PQube® 3. It is powered from 24VDC, which is
supplied by the PM2 Power Supply module.
The ATT2 module comes in two versions: 600V and 1200V full scale. Two banana jacks are used for
the high voltage measurements, and a hall-effect sensor is used for measuring current.
For best results, the current sensor is factory-calibrated together with your ATT2 module. We
recommend to purchase ATT2 and its current sensor within the same order.
Note: The ATT2 module can also be used to monitor AC power
