APPLICATION
The WSX10X energy meters are used for measuring energy
using direct connection in three-phase systems with current
up to 65A while the WSX30X meters are used for connection
with current transformers. Optional also the measurement of
apparent energy is possible. Housing is provided with
terminals protection covers, which can be seal up against
non-authorised access. They are built to be fastened to
EN 60715 standard guides. The meters are microprocessor
controlled. Display of quantities depends on meters type.
They can be displayed on 7 digit electromechanical counter
or on LCD display.
According to the customer's demands, meters can be
equipped with a RS485 serial communication (option) with
the MODBUS protocol, which enables data transmission and
thus connection of the measuring places into the network for
the control and management with energy. They can also be
equipped with tariff input (option).
A built-in pulse output (option) is designed for sending data
to the devices for checking and monitoring consumed
energy.

LAYOUT AND MODE OF OPERATION
A method for sampling voltages and currents with an A/D
converter is used. Current inputs are electrically isolated
from the system by means of measuring transformer (4)
(Picture 4), voltages are measured by the resistor voltage
divider (3). Input currents are amplified in programmable
amplifier (5). After A/D conversion the signal is computed in
microprocessor (6). Not only data on the meter type but also
calibration constants are stored in the EEPROM (7). There
are no adjustable elements (potentiometers) in the meter,
which assures a better long-term stability. A built-in auto
range of current inputs assures accuracy also at small
currents. High rate of sampling enables measuring distorted
signals, as well.
One or two (optional) S0 output (10) is built into each meter.
A number of pulses depend on consumed energy. Measured
quantities are displayed on 7 digit electromechanical counter
(11) or on LCD display (8). LED diodes (9) are used for
detection of starting current, indication of communication
(transmission) and test output proportional to measured
power. LED diodes are only built in WS0X01 and WS0X02
meters.
Galvanic separated communication (12), RS485 enables
data transfer and tariff setting. Tariff can also be set via tariff
input (13) (option).
The meter is supplied from the measuring system. The
instrument electronic part is supplied via the supply
rectifier (2).

DATA FOR ORDERING
Sample:
Two tariff active energy meter for direct 4-wire connection
50 Hz 5(65) A with RS485 and one impulse output MID
approved - WS0102 model 41112210
* - Not available for MID approved meters
** - Quadrants of registered energy
*** - For MID approved meters with primary metering the primary
current must be specified at order - fixed parameters. For industrial
meters WS030X the primary current of CT shall be specified for
primary metering due to counter resolution. For industrial meters
WS1302 with RS485 communication any primary current of CT and
resolution can be set afterwards using communication.
