N27P Power Network Meter

The N27P is a programmable digital device used to measure the parameters of single-phase electrical networks. The meter measures and calculates the following values:
phase voltage
10 minutes’ mean voltage
current
active power
reactive power
apparent power
active power factor
ratio of reactive/active power
mean active power
phase shift
input of active energy
output of active energy
input of reactive energy
output of reactive energy
apparent energy
frequency
10 seconds’ mean frequency
time
maximum and minimum values of:
– phase-to-neutral voltage;
– current;
– active power;
– reactive power;
– apparent power;
– active power factor;
– tangent φ;
– frequency;
– average active power;

It is possible to enter transformer ratio of used external current or voltage transformers which will be accounted for in the measurement and calculation of all values. All values and configuration
parameters are accessible through the RS485 and USB interfaces.The meter output signals are galvanically isolated from the input and power supply signals.

NA3 Digital Meter With Bargraph

NA3 series meters with a multi-colored bargraph have an universal input destined to measure temperature, resistance, voltage from shunts, standard signals, d.c. voltage and d.c. current. NA3 meters can optionally have a continuous analogue output, relays, OC type (Open Collector) and digital RS-485 outputs. They can find application in various industrial fields, e.g. food industry, intermediate pumping stations, sewage treatment plants, chemical industry, weather stations, breweries.
NA3 meters are executed in three basic versions:
 NA3-F with a 4-digit LED readout field (digit height: 7 mm) and a multicolour bargraph,
 NA3-D with a 4-digit LED readout field (digit height: 14 mm),
 NA3-B with a multicolour bargraph.
The type choice is made in the execution code.
They are programmed by means of the keyboard and through RS-485. Meters only with the bargraph can be programmed through RS-485.
NA3 meters realise following functions:
– measurement of the input quantity and displaying it on the display and/or the bargraph,
– evaluation of the input signal into indication on the base of the individual linear characteristic,
– programming of the colour and bargraph resolutions (no concerns NA3-D),
– signalling of alarm value setting exceeding,
– recording of the measured signal in programmed time segments,
– storage of maximal and minimal values,
– programming of the indication resolution,
– programming of the measurement averaging time,
– locking of the parameter introduction by means of a password,
– conversion of the measured quantity into a voltage or current output signal,
– service of the RS-485 interface in MODBUS protocol, both in ASCII and RTU mode.

NA5 Digital Meter With Bargraph

NA5 series meters with multicoloured bargraphs have an universal input destined to measure temperature, resistance, voltage from shunts, standard signals, d.c. voltage and d.c. current. They can find application in various industrial fields, e.g. food industry, intermediate pumping stations, sewage treatment plants, chemical industry, weather stations, breweries. They are destined for the visualisation of the measured value and evaluation of change trends of checked technological processes. They can also find application in automation systems where programmed controllers are applied. NA5 meters can have in option: a continuous analogue output, a relay output, open collector (OC) type outputs and an RS-485 digital output. They are programmed by means of the keyboard and through RS-485.
NA5 meters realise following functions:
– measurement of the input quantity and displaying it on the display and the bargraphs,
– recounting of the input signal into indication on the base of the individual linear characteristic,
– arithmetical functions: raising to a power, extraction of roots,
– programming of colours and bargraph resolutions,
– signalling of alarm value setting exceedings,
– recording of the measured signal in programmed time segments,
– storage of maximal and minimal values,
– programming of the measurement averaging time,
– programming of the indication resolution,
– deadlock of the parameter introduction by means of a password,
– conversion of the measured quantity into a voltage or current output signal,
– service of the RS-485 interface in MODBUS protocol, both in ASCII and RTU mode.
