HQ15 5A 100A High-value voltage output AC current clamp sensor

voltage output current clamp sensor

The HQ15 100a current clamp sensor is designed for easy installed in tight spaces and without the need for dismantling the primary busbar or cables. The sensing head uses sliding push-fit clamp structure, safety isolation to avoid the user to contact with charged objects directly. It complies with CE standards and meets 300V CAT III safety class. This model HQ15 AC current sensor is a high accuracy mini current clamp probe for measurements up to 130A AC. This current probe uses a special magnetic core to provide higher accuracy and lower phase shift. The HQ15 Series current clamp is an excellent probe sensor to be used in power and low level current measurement applications.
