Vacuumschmelze 1000A High Current Industrial Sensors are designed for a current of up to 1000Arms with a measuring range of up to 2500Apeak. These VAC Industrial Current Sensors offer low offset and gain errors, low temperature drift, and excellent long-term stability. These sensors also offer low power consumption due to PWM compensation current drive stage. They also offer excellent dynamic properties (rise time, pulse response) due to a low winding capacity of the compensation current winding.
Current Transformers
Vacuumschmelze offers a variety of high-performance Transformers, including Power Line Coupling (PLC), Gate Drive, Current, and Interface devices. VAC current transformers for electronic electricity meters are a new series of DC-tolerant VITROPERM® CTs with high linearity performance and a very compact design.
Transformers
Vacuumschmelze (VAC) Transformers encompass a variety of high-performance transformers, including Power Line Coupling (PLC), Gate Drive, Current, and Interface devices. VAC Powerline Transformers are designed specifically for Advanced Metering Management (AMM) systems. These transformers are ideal for smart meter applications. VAC also offers a range of audio and signal interface transformers.
Current Sensors
Vacuumschmelze (VAC) Current Sensors utilize amorphous field detector technology which makes the sensor more accurate and also improves linear performance with changes in temperature. The main function of VAC Current Sensors is measuring currents from DC up to high frequencies (approximately 200kHz). These sensors contain a galvanic separation between the primary circuit and the output signal (according to EN 50178 or EN 61800) and typical currents range from a few amperes up to several hundred amperes full range. Some sensor types can measure more than 1000 ampere peak current. The accuracy of the VAC current sensors lies in the range of <1% of the nominal current. The VAC-invented measuring principle of the closed-loop sensor with magnetic probe as a zero field detector is distinguished by maximum precision of the current detection. The detected currents range from 6Arms to 700Arms.
