5 average power values P, Q, S each
Application
The A 210/A 220 power measuring instrument is suitable for control panel mounting and measures all the important measurands in 3-phase and single-phase systems.
It displays the measurands with a high contrast 14 mm high LED display. The instrument is also suitable for measurements in high and middle voltage systems because of the freely programmable factors for the current and voltage transformers.
It replaces a large number of analog instruments and delivers highaccuracy values.
The basic execution is an instrument with 2 S0-outputs, which can be programmed as pulse or limit outputs. An extension module extends the functionality and flexibility and supports programming and communication via an RS 232/485 (selectable) interface. It supports data communication with a control system via MODBUS RTU and it can be added without making changes to the basic instrument. Memory and a digital input allow the monitoring and recording of average power values for a minimum of 83 days at 15 min intervals. This function enables the load profile to be determined. Alternatively, the digital input can be used to switch between the high and low tariffs.

SINEAX A 210/A 220
Multifunctional Power Monitor
Function
The instrument measures the currents I1, I2, I3 and the voltages U1, U2, U3, the frequency, and the phase angles between the individual currents and voltages. All the other measurands are calculated from these. The measurements are made internally via integrated current transformers. Therefore it is possible to make direct connections without an external transformer.
Each input is sampled 32 times per cycle. This allows measurements to be made including up to the 15th harmonic.
The calculation of the measurands is made in accordance with DIN 40 110 part 1 and part 2, however in 4-quadrant operation.

SINEAX A 210/A 220
Multifunctional Power Monitor
Programmable values (basic unit)
Trip points, pulse rate, transformer ratio, type of system, interval time for average power values.
Programming can be locked with a jumper at the back of the instrument.
However, the limit values can still be changed.
All min. and max. values and the counter values can be reset. The resetting of the counter values can also be blocked with the above mentioned jumper.
All the measurands, the selected display, the counter values and the programmed data are kept on a power failure.

The frequency is measured from the current or voltage. The voltage has priority.
Pulse/limit value outputs 
Depending on the function selected, the two digital outputs can be used either as pulse outputs for actual and reactive energy or as limit signals.
The outputs are passive, and are galvanically isolated from all the other circuits by opto-couplers. They are suitable to drive tariff devices (S0-standard DIN 43 864) or 24 V-relais.
