AD-LU 35 GT
Description
The digital power measuring converter AD-LU 35 GT measures all magnitudes of the three-phase network (current, voltage, energy, effective power, reactive power and apparent power..) and makes this data available via a RS485 bus. The unit is therefore optimally suitable for integration in energy management systems. 3- or 4-conductor networks can be measured. 4-wire networks can be loaded balanced or unbalanced, whereby 3-wire networks can only be measured balanced. The AD-LU 35 GT supplies itself via its measuring voltage L1. The current measurement takes place via additional external Split-Core-Transformer. The device is therefore ideal for retrofitting if no space is available. For measuring high voltages or currents, external converters can be fitted in series at any time. A Modbus-RTU protocol is run via the RS485 bus interface, whereby the AD-LU 35 GT represents a Modbus slave. The bus address is set via the rotary coding switch mounted at the front, this way several of these measuring units can be switched at one bus and can be interrogated from one central point. The AD-LU 35 GT can also be read and parameterized via the available AD-Studio. Two LEDs at the front signal the operating condition and the RS485 data traffic. The compact type of construction and the high performance ability, with simultaneous low energy consumption, allows usage in almost any application.
Application
A typical usage is in energy management systems for balancing and determining the energy distribution. Due to the measurement via an external current transformer, the unit can be retrofitted without problems in any system without interruption.
