WBV412S01 AC Voltage Transducer
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
WBV412S01 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 (in any wave form) 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 500V, it needs
dividing input voltage by using resistor which is provided by
Weibo electronic. Different transducer uses special resistor.

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.
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;
