1. Introduction
This chapter describes the general characteristics and main features of the CT-
100/CT-150 DC current transducer series
<
.
1.1 CT-100/CT-150 Series Overview
The
<
(O-FLUx Current Sensor) family is based on a closed loop technology
that allows accurate and precise monitoring of DC and AC currents with high
bandwidth.
The internal conductive casing guarantees higher noise immunity and reduces
undesired noise pick-up from external sources. The transducers CT-100/CT-150 family
has a transform ratio of 1:1000 (CT-100) and 1:1500 (CT-150) between primary and
secondary. External plastic casing guarantees galvanic isolation between the primary
and the secondary circuits in order to allow to current measurements at a different
potential and simplifies interfacing when using the
<
,
as the feedback element of
current regulated power supplies.
Output from the CT-100/CT-150 transducers can be chosen between two
different versions: standard secondary current output or buffered voltage output (low
temperature coefficient shunt resistor and low-noise amplifier are embedded in the
internal electronics in the “V” model). Connections for power supply and output signals
are available in two different versions: the DB-9 connector (
“C”
-version) and a 7-pin
through-hole strip (
“P”
-version).
Main characteristics of the entire
<
family are negligible temperature
coefficient, excellent linearity and extremely low noise.
DC current transformers and transducers represent the ideal replacement for
systems where Hall-effect sensors or shunt resistors are used as current sensing
elements and better performances are needed.
The compact mechanical dimensions of this transducer series and its limited
weight, as well as the DB-9 connector version, allow easy mounting on printed circuit
boards with a Through Hole (TH) topology for the
“P”
-version and on racks for the
“C”
-version.
Main application fields for these current transducers are precise and extremely
stable regulated power supplies and power inverters.
