RCT
series flexible split core current sensors with
0-5V, avoiding LV & HV shutdown |
The RCTi, RCTi-3ph and RCTrms are ideal for retrofit
replacement for medium/large current, split core current transformers operating with
transducers. Excellent performance at power frequencies 1Hz to 1MHz, also ideal for
VFD drives and induction heating. The new RCTi and RCTrms current sensor/transducers are
suited to permanent or semi permanent installation. The coil sensor is
durable, thin, lightweight,
flexible and will easily clip-around the conductor. The output from the transducer can be
ac voltage (RCTi, RCTi-3ph) or a true rms output (RCTrms).
Typically the RCTi is used with data loggers, oscilloscopes, data acquisition cards, power
analyzers, harmonic analysis and in power quality applications. The RCTrms is used
in process control Scada Systems and industrial power applications, where a
dc output represents the rms ac current.

Flexible core
current transformers with 1A or 5A output |
|
NEW COMPACT -
ALL IN ONE WITH 1A OUTPUT
Model RCT1A - Any ratio from 100/1A to 50000/1A
The RCT1A current
probe has a 1A secondary current output - current sensing is based on a Flexible Core
Loop. The RCT1A is a 1A output Flexible current probe.
The TA module is used for interfacing existing RCTi and IRF current probes to existing 1A or 5A metering circuits. The
TA module converts the RCTi/IRF voltage output to 0-1A or 0-5A signal. Unlike
conventional CTs, there are no open circuit hazards, these are ideal with
installations in confined spaces. The RCT1A, RCT/TA5V-5A
combination simplifies
installation and eliminates the need for expensive LV/HV plant shutdown.
Models from 100/1A to 50000/1A, Accuracy Class 1 (1%) at 5VA. UL/CSA
