MaCC plus - external current sensor<br />

This is the most popular current sensor available, with a<br />

1000:1 current transfer ratio for maximal 850Apk (600Arms).<br />

In case of DC currents, max. 600Adc can be measured<br />

continuously. Also types with voltage outputs are available;<br />

■ 100Apk/10Vpk and 200Apk/10Vpk & 500Apk/10Vpk.<br />

■ With overload capacity of 20%, sinusoidal currents can be<br />

measured of respectively 85Arms, 170Arms and 430Arms.<br />

■ Maximum continuous DC currents are the same as the ACpeak<br />

limits.<br />

Can be used with the junction unit HUB4MACC to minimize<br />

wiring. The “current-in/current-out” type has preference over the<br />

“current in/voltage out” type, mainly because of better noise<br />

behaviour of the signals between the junction unit and the low<br />

impedance of the power meter current shunt.<br />

SC1000 - Split Core zero-flux TM current measuring<br />

system<br />

Often it is not possible or allowed to swit<strong>ch</strong>-off a motor used<br />

in a production facility or in a critical safety environment like<br />

a nuclear power plant. Also it can be inconvenient and costly<br />

to remove and replace eyelets of thick power cables in order<br />

to run them through the sensor hole. The new SC1000 high<br />

precision split-core current sensor solves these issues.<br />

■ Measures primary currents up to 1000Apk (700Arms).<br />

■ Transfer ratio is 1000Apk/0.5Apk or 1000Apk/10Vpk in<br />

case of a voltage output.<br />

■ The SC1000 can be used with the junction unit<br />

HUB4MACC to minimize wiring.<br />

CuraCC - zero-flux TM current measuring system<br />

If 1000Apk (700Arms) is not enough, then there is the<br />

CURACC-series, up to 6000Apk (4240Arms) for “current-in<br />

current-out”. Up to and including 2000Apk (1400Arms) we<br />

advise the head model B encapsulated, a resin encapsulated<br />

head that is more robust for industry applications. Between<br />

2000Apk (1400Arms) and 6000Apk (4240Arms) the head<br />

model E with side plates is advised for easy mounting and<br />

robustness.<br />

■ Output current always 1Apk at the primary peak current<br />

level as defined by the customer.<br />

■ In case of DC currents, max. 2000Adc (model B) resp.<br />

6000Adc (model E) can be measured continuously.<br />

■ Can be used with the junction unit SUM3 or SUM4 to<br />

minimize wiring.<br />

for every application there is a solution. please contact your local<br />

<strong>Yokogawa</strong> or hitec representative if you have even more demanding<br />

applications.<br />

The input current producing the specified output signal (1A or 10V) can be <strong>ch</strong>osen between<br />

±150Apk and ±6000Apk.<br />

Example: A CURACC ordered with a transfer ratio 500A/1A can measure currents from -500Apk<br />

to +500Apk, producing -1Apk to +1Apk at the output.<br />
