High-Voltage Isolation Amplifiers / Shunt Isolators

VariTrans P 29000
Compact high-voltage isolators with safe galvanic isolation,
VariPower broad-range power supply and genuine calibrated range selection.

The Task
When it comes to taking measurements on
power electronics, unipolar or bipolar voltage signals ranging from 20 mV to 1000 V
must be galvanically isolated and converted
to standard ±20 mA, ±10 V, or 4 … 20 mA
output signals.
The Problems
Room in the enclosure is limited and expensive. Therefore great value is placed on the
miniaturization of automation components.
And high safety requirements with regard to
the protection of persons and systems must
also be met.
The Solution
The VariTrans P 29000 isolator series is
designed specifically to measure voltages
up to 1000 V AC/DC. The test voltage is
5.4 kV AC. Protection against electric shock
is achieved through protective separation
according to EN 61140 between input and
output and power supply.
Compact automation solutions can be
implemented thanks to the 17.5 mm modular housing and operation at temperatures
up to 70 °C.

The Advantages
The measuring ranges of the VariTrans
P 29000 are adjusted via DIP switches on the
front side of the modular housing. Calibrated switching is controlled by a microcontroller. This makes for very easy configuration requiring neither calibrators nor other
measuring equipment. The user can select
from up to 192 switchable calibrated ranges.
In addition to the active current or voltage
output, a passive current output allows for
connection to active PLC inputs. LEDs indicate proper functioning or possible fault
conditions, such as exceeding of the allowable load voltage at the output. The simple
implementation of special measuring
ranges supports solutions tailored to your
application. An optional RangeLimit function lets you set lower and upper output
limits on the isolation amplifiers.
In addition, versions with full-wave rectifiers
in the signal path are available. The output
can be inverted by the user. A connectable
potentiometer enables zero point adjustment of up to 5 % on the measuring section.

The Housing
With a width of only 17.5 mm, the modular
housings of the P 29000 series strike an optimum balance between compact design and
safety. The relevant safety standards are
­reliably met.
For direct measurement of the output current, the device features test jacks which
enable measurement of output current and
voltage; the output circuit doesn't have to
be interrupted to do so.
