QI-50-V-485, QI-300-V-485 (150 / 300 Amps Switchable)

AC/DC "CT" STLYE RS485 MODBUS SERIAL OUTPUT CURRENT TRANSMITTER

The QI-50-V-485 and QI-300-V-485 are moulded case high accuracy universal DC or AC current transducers / transformers galvanically isolated from the measuring circuit. The “CT’s” are available as a 0-50 Amp fixed range unit, or a switchable, via dip-switch primary current range of either 0-150 Amps or 0-300 Amps and is equipped with both a 0-10VDC dampened output and RS485 MODBUS serial communications.
QI-POWER-485, QI-POWER-485-LV, MODBUS RTU OUTPUT ENERGY METER, RS485

ASC/DC "CT" STYLE RS485 MODBUS RTU OUTPUT ENERGY METER


The QI-POWER-485 and QI-POWER-485-LV are moulded case high accuracy “CT” style universal DC or AC multi parameter energy meters and are galvanically isolated from the measuring circuit. The “CT’s” have a primary current range of 0-50 Amps AC/DC and for voltage up to 800VAC or 1000VDC (LV version 80VAC or 100VDC).

AC/DC "CT" STYLE RS485 MODBUS RTU OUTPUT ENGERGY METER


The QI-POWER-485-300 and QI-POWER-485-300-LV are moulded case high accuracy “CT” style universal DC or AC multi parameter energy meters and are galvanically isolated from the measuring circuit. The “CT’s” have a primary current range of 0-300 Amps AC or 0-400 Amps DC and for voltage up to 800VAC or 1000VDC (LV version 80VAC or 100VDC).
SCL, SCT, ROPE, ROGOWSKI, SPLIT

SPLIT CORE 333mVAC SECONDARY CT's


The SCT and SCL range of split core 333mVAC secondary current transformers are designed for fast and easy installation with no need to disconnect any loads. An internal precision resistor across the secondary winding of the CT provides a safe, low voltage output of 333mVAC with minimal current. Unlike conventional 5 Amp and 1 Amp secondary CT’s, where the VA burden in the secondary circuit, against the VA that is available from the CT, has to be taken into consideration.  Meaning how far away the CT from the meter can be maximally sited needs to be calculated.  With 333mVAC secondary CT’s this is not relevant. The SCL range is supplied with 1 metre of flying lead cable and the SCT range with 2 metres.


The ROPE range of “flexible” Rogowski Coil current transformers are supplied only in sets of 3 in either lengths of 461mm or 610mm. The set of three are supplied with a 5VDC nominal power supply with a 100-240VAC primary to excite the CT’s. These CT’s also have a 333mVAC secondary and are extremely flexible making them particularly suitable when CT’s are required to be fitted retrospectively in awkward situations. They are supplied with 2 metres of captive cable.
