AHM3 ENG SLIDE1

AHM3 Network analyzer

The AHM3 network analyzer is designed for the calculation and measuring de electrical variables of a grid such as voltage, current, frequency, power, power factor, energy, harmonic components, etc. in the low, medium and high voltage distribution.

 It is able to measure single, two or three phases, and can be used in systems of two, three and four wires, so as TN, TT and IT systems. There are four interfaces in the AHM3 for additional modules used to extend their functions.

 

The AHM3, can be considered one of the most complete market analyzers providing different solutions to industrial level.

 

MODEL ORDERING CODE
AHM3 ZAHM3

 

We emphasize the following features:

– In addition to showing the typical electrical variables of a network such as voltage, current, frequency, power factor… shows up to 63th harmonic signal. This value reports on the quality of the existing signal, thus protecting the possible failure, deterioration or warming in the connected machines and saving money to the user.

 Can be programmed for single-phase, three-phase 3-wire, three-phase 4-wire, nominal current 1 and 5 Amps and nominal voltage up to 690 V AC

Its capacitive keypad provides high quality and durability unlike conventional mechanical keyboards.

Available in two languages; Spanish and English.

Display waveforms.

It has 4 interfaces on the back to add additional modules.
