1. INTRODUCTION
OR-WE-512, OR-WE-514, OR-WE-515 are single-phase, single-module counters with backlit LCD display, for mounting on a DIN rail.
They are used to monitor electricity consumption of a single-phase network. They are ideal for use as an AC meter. Their width is only
18 mm, but they comply with the RS485 communication standard and comply with DIN EN 50022, which is suitable for power
distribution in domestic and commercial applications.
2. TECHNICAL CHARACTERISTICS AND PARAMETERS
2.1 Characteristics
The meter can read network parameters, analyze energy quality and load status over a
certain period.
For mounting on a standard DIN rail - only 18 mm wide.
OR-WE-514 The meter has the ability to register the consumed electricity with the
possibility of remote reading of group registers through the RS485 standard wired network,
protocol: Modbus-RTU mode.
OR-WE-515 The meter has the ability to register consumed electricity with the option of
remote reading of indicator group registers via the RS485 standard wired network,
protocol: Modbus-RTU mode and 4 independent tariffs (the user can set different times via
RS485).
The meters have a lithium battery for the real time clock. Real time clock accuracy is 0.5 s
per day.
Backlit LCD display.
Scrolling the display of current (A), voltage (V) etc.
Accurate measurement of active and reactive power.
2 data display modes:
a. Automatic scrolling mode: the time interval is 5 s.
b. Button mode - using an external button to check data.
* Base current - specifies the current value at which the percentage measurement error is close to zero. If the current flowing through the
meter is greater than the basic one, then the measurement error has a negative sign. If the current flowing through the meter is less than
the basic one, then the percentage measurement error has a positive sign (percentage measurement error as a function of current).
The meter measures electricity correctly with the accuracy of the meter class over the entire measuring range.
Maximum current - is the maximum current at which we can constantly charge the electricity meter.
Minimum current - the lowest load current that the meter detects and registers.
