DC Current Sensors
Cost-effective DC current sensors are used to measure DC electrical current in industrial settings. Engineered for accuracy and durability, they are suited to deliver precision current measurements in DC applications like renewable energy or transportation. Choose from several factors including split-core DC current sensors, DC current shunts, or DC voltage sensors.
DC SENSOR
HAB-16555
Split-core DC current sensor with 0.5% accuracy. Available with one of five input ratings & either 4-20mA or 0-5AV output. Unidirectional & bidirectional models available. Non-invasive, split-core design can be easily integrated into existing installations.
DC SENSOR
HAK Series
Split-core DC current sensor with 0.5% accuracy. Two sizes available with either 4-20mA or 0-5V rated output. Measure up to 1000A DC current (depending on model). Unidirectional & bidirectional models available. Compact split-core design facilitates fast, non-intrusive installation.
DC SHUNT
DC Shunt Series
DC current shunts with 0.5% accuracy. Seven available sizes & input ratings from 50A to 4000A (depending on model) each with a voltage drop of 75mV. High-precision resistor provides reliable measurements in any DC current system.
HV2
HV2 Series
Surface mount voltage sensor with 0.5% accuracy. Choose from 1000V, 1200V, or 1500V input rating to measure DC voltage across a wide frequency range. High immunity to interference maintains performance in harsh environments. Compatible with DC power meters.
