T Series - Loop powered in-field converters
Overall description
The T201DCH100 and 300 are isolated, contact less loop powered AC/DC current
transducers. The look and device’s function are very similar to those of an active
standard Current Transformer, but with the remarkable feature of measuring the
TRMS DC and AC component or DC bipolar of the current. For its electrical endurance,
ease of use and compact dimensions, the T201DCH100 and 300 fit every kind of current
measurement: up to 100 Adc/Aac and 300 Adc/Aac (respectively).

STANDARDS
Standards
EN61000-6-4 (electromagnetic emission, industry).
EN64000-6-2 (electromagnetic immunity, industry).
EN61010-1 (safety).
Mounting
The device can be located in any position and place, in accordance with the operating
conditions above stated. Use the included holder bracket when fixing to a DIN rail.
WARNING
: High-strength static magnetic fields may change the output value: let avoid
closeness to permanent magnets, electromagnets or iron bulks that cause such a modifi-
cation of the surrounding magnetic field; try a different arrangement or orientation if zero-
error was greater than expected.
Multi-turn primary winding to improve sensibility
You can increase the sensibility of the device passing several times trougth the hole with
the measuring current cable, realizing turns with multiplicative effect: e.g. passing 5
times trougth the hole, as to see 4 turns,choosing a 100A range, you get an equivalent
sensibility of 20 A full-scale. When you make this, let dispose the turns with symmetry in
order to preserve accuracy: use diametric contraposition with 2 turns, cross disposition
with 4 turns, and so on.
Disposal of electrical & electronic equipment (applicable throughout the EU and other countries wit separate collection programs). This symbol, found on your product or on
its packaging, indicates that this product should not be treated as household waste when you wish to dispose of it. Instead, it should be handed over to an applicable collection
point for the recycling of electrical and electronic equipment. By ensuring this product is disposed of correctly, you will help prevent potential negative consequences to the
environment and human health, which could otherwise be caused by inappropriate disposal of it. The recycling of materials will help to conserve natural resources. For more
detailed information about the recycling of this product, please contact your local city office, waste disposal service or the retail store where you purchased this product.
