WBV414H29 AC Voltage Transducer
Product Description and Application
WBV414H29 converts AC input voltage into a load independent output signal dc 0mA-20mA or
4mA-20mA. It has adopted electromagnetic isolation principle and average measurement method
for real time measurement of AC voltage (in any wave form) from electric net or electric circuit.
The product has certain advantages of total galvanic isolation among input、output and auxiliary
power, high accuracy, low drifting by temperature, and wide temperature bearable range, etc.The
product meets EN61326：2006 and EN60100：2001 standard.

Instruction of Installation
1. The product has adopted structure compliance with EN50022; suitable for DIN rail mounting
NS35/7.5, NS35/15. Installation steps are as following (please reference to dimensional drawing):
Step 1: Immobilize one side of product‘s mounting trough to the DIN mounting rail;
Step 2: Pull out the spring clasp;
Step 3: Place whole mounting trough to the DIN mounting rail properly;
Step 4: Release spring clasp to make sure the installation.
2. The product has calibrated before out of factory. After correctly wiring, it can be powered and
used immediately. But for further precise signal sampling, user need to warm-up the product for 3
minutes before use.
3. output signal (Iz) is designed to follow the impedance load value of 250Ω; When Resistance
(R1 ) is less than 100Ω, the user must add output current circuit a power reduced resistance load R0
to keep the summation of total impedance value is between 100Ω～250Ω
4. basic testing method for accuracy
(1) According to the terminal definition table to connect the testing circuit;

(2) The testing must to be done by under the following conditions；
Auxiliary power: nominal input±5％
Ambient temperature: 25℃±5℃
Relative humidity: RH(45～75)％
Accuracy for Signal Power Source instrument: 0.05
(3) warming up the transducer for 3 minutes
(4) using output monitoring meter V1 to measuring the output of signal power source
instrument, set a any input value which is within the measuring range of the transducer Ur. (for e.g.
if input value is 100V, the output is 4mA-20mA, the expected output value Iz should be calculated
as:
Iz = (20mA－4mA)×Ur/100V＋4mA
(5) using output monitoring meter V2 to measuring the output voltage V0 of the transducer,
the basic introduced errorγof the transducer should be calculated as:
γ= (Uo－Iz×250Ω)/[(20mA－4mA)×250Ω]×100%
(6) Repeating (4) (5), if calculated absolute value is less than the given accuracy value of
the transducer, it shows the transducer’s accurate grade is qualified.
Caution:
1. Pay attention to the auxiliary power information, especially the auxiliary power grade,
and polarity, other wise will damage the product.
2. pay attention to the wire connection; wrong terminal connection will cause
malfunction of the product and even damage the product;
3. The product only be used for testing the AC wave shape that with low harmonic wave.
4. Don’t dismantle the product, and carry with care to avoiding bump and fall of the
product;
5. If the product has been using under the environment with strong Electromagnetic field

interference, please pay attention that output signal wire should use shielded wire. And
double-pointed of the shielding layer should be connected with protective earth . For
product intensive installation, the space between each product should not be smaller
than 10mm.
6. Only use identified terminals.
7. The input that be given by the product tab means the virtual value of the AC signal .
8. There is no lightening strike prevention circuit design in this product. For out door and
hazardous environment using, please add protective alternatives.
9. This product uses fire prevent ABS crust, its temperature withstand is only limited as
+85℃, higher than this limitation will cause the product deformation. Please use and
store carefully.
10. Please do not destroy or change the product label, symbol, and do not disassemble the
sensor, or else we will not provide the product warranty.
11. The product cannot be recycle used.
