Model
W22-2
Country
Italy
Type
Wattmeter relay
INPUTS
Voltage pins : 23-21-19.
Input Resistance = 800 kW
See REMARK 4.
Current pins : 15-14.
No specific order to be followed.
The maximum three-phase voltage is
415Vac; the maximum monophase
voltage is 240Vac (see REMARK 6). For
higher voltages, it is requested the
application of:
M 08: Three-phase drop resistances +
CT for insulation.
OUTPUT RELAY
5A(NO) 3A(NC)-230 Vac resistive load
R1 9-10 NO
9-8 NC Device not supplied
R2 5-6 NO or in alarm
5-4 NC
ANALOG OUTPUT
Pin 26(+) and 25.
0÷5Vdc IMAX = 1mA
The theoretical value of “full scale”
power shown in the tables A, B, C
allows to give the “WEIGHT” to the
Analog Output Volts. Ex.: with full scale
of 5A (V=400 Vac) the 5V of the Analog
Output corresponds to 3,45 kW,
therefore 1V = 3,45/5 = 0,69 kW
SUPPLY: (single voltage)
2VA 50-60 Hz - tolerance ±10%
13-12: 24Vac or 48Vac or 115Vac or
230 Vac
INSULATION
Galvanic separation it is given by the
supply transformer and internal C.T.
CASE
70x75x110 mm for DIN rail.
E 405B transparent front cover for tight
closure (on request).
WORKING TEMPERATURE: 0÷70°C
WEIGHT: Kg 0,300
COLOUR: grey, similar to RAL 35.
FUNCTION
The wattmetric relay W 22-2 measures
the voltage (V) and the current in the
line (I), besides it computes the cosφ
and the ACTIVE POWER as product of:
W = 1,73 V I cosφ
USE
The electric motor is the most common
load to be controlled by an active power
relay. The active power supplied to the
motor gives the direct information of the
instant load of the motor itself.
Such information is more accurate than
the one given by the current value.
As a matter of fact the cosφ variations
may change the power value without
affecting the current value.
