Safety claim
The information in the safety claim of the equipment documentation is intended to ensure that equipment
is properly installed in order to maintain it in a condition.
It is assumed that everyone who will be associated with the equipment will be familiar with the contents of
that safety section, or this safety guide.
When electrical equipment is in operation, dangerous voltages will be present in certain parts of the
equipment (e.g. the input terminal). Failure to obverse warning notices, incorrect use, or improper use
may endanger personnel and equipment and course personal injury or physical damage.
Before working in the terminal strip area, the equipment must be isolated.
Proper and safe operation of the equipment depends on appropriate shipping and handling, proper
storage, installation and commissioning, and on careful operation, maintenance and servicing.
The operating manual for the equipment gives instructions for its installation, commissioning, and
operation. However, the manual cannot cover all conceivable circumstances or include detailed
information on all topics. In the event of questions or specific problem, do not take any action without
proper authorization. Contact the appropriate WB technical or sales office and request the necessary
information.

Product Description and Application
WBV412U01 converts AC input voltage into a load independent output signal DC voltage 0-5V. It has
adopted electromagnetic isolation principle and average measurement method for real time
measurement of AC voltage from electric net or electric circuit.
The product has certain advantages of total galvanic isolation between input/output, high accuracy, low
drifting by temperature, and wide temperature bearable range, etc.

Instruction of Installation and Use
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.
a) the auxiliary power requires isolation voltage≥2000VAC, DC current output ripple＜10mV.
b) When transducer measuring voltage exceed 1000V, it needs dividing input voltage by
using resistor which is provided by Weibo electronic. Different transducer uses special
resistor.

c) Measuring voltage ≤ 600V, uses terminal 3 and 1;
d) Measuring voltage ＞600V, uses terminal 3 and 4;
3. 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: 24V±1％, ripple≤5mV
Ambient temperature: 25℃±2℃
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 Vr. (for e.g. if input value is 100V, the output is 0-5V, the expected output
value Vz should be calculated as:
Vz=（5V-0V）× Vr/100V
(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= (Vo－Vz)/（5V-0V）×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.
