Description
The CTUB100 series of current transformers are combinations of CTBC… measuring current converter cores and CTUB10… electronic modules that can be used for AC and DC currents
Convert evaluable measuring signal. The measurement signal can be evaluated using devices of the series RCMA420/423, RCMS460/490 or EDS440/EDS441LAB.
The measuring current transformers are connected to the respective devices via a 2 or 6-wire cable. They can be used in DC, AC and 3(N)AC systems
other.
The CTUB101-CTBCxx transducers are used for connection to the devices The RCMA420/423 series and are connected via the 6-wire cable Directly from the processing unit
Supplied with the supply voltage DC ±12 V. The CTUB102-CTBCxx transducers are intended for connection to a RCMS460/490. If the CTUB102-CTBCxx transducers are connected to a RCMS460/490 system, a 24 V DC power supply unit is required for the transducers, which is available as an accessory.
The CTUB104-CTBCxx transducers are intended for connection to a EDS440 or EDS441LAB. The CTUB104-CTBCxx transducers are connected to one
Insulation fault detector is connected, a 24 V DC power supply unit is required for the current transformer, which is available as an accessory.
The CTBC20P…210P series of current transformer cores have built-in magnetic shielding and are suitable for applications with high load or inrush currents.
