Magnelab’s HCT-0024-250 is a DC Current Transformer taking up to 250A and outputting 4V. It has a 24 mm opening.
This open loop DC current transformer (hall effect sensor) can be used to measure both DC amperage as well as AC amperage signals up to 250A. The output type (AC or DC) reflects the type of the input amperage. The HCT-0024 is very compact and lightweight. It has an offset voltage less than +/-30 mV. It is +/-1% linear.
Temperature has a ± 0.1% /°C effect on the HCT-0024. It uses accurate laminating core split technology and is designed for strong durability while providing accuracy in low current situations. The HCT-0024 is a compact one-touch split structure, allowing easy installation. It is 1% accurate at the rated current and passes IEC61010-1, UL61010-1, and EN61010-1.
The HCT-0024’s insulation can withstand an AC voltage up to 1500V for 1 minute. It typically has a 3 μ sec response time at full scale current.
When searching for compatible power meters, look for meters on our website that accept a Vdc input. These meters will show the following symbol as the input:
To power the HCT-0024 you will need a +/-15Vdc power supply (+/-5%).
