Transducers For Measurements Up To
20000ARMS
LEM has introduced the HAZ family of current transducers for measurements from 4000A up to 20000Arms nominal, with six models housed in the same 250 x 160 x 50mm package.
LEM has introduced the HAZ family of current transducers for measurements from 4000A up to 20000Arms nominal, with six models housed in the same 250 x 160 x 50mm package Each is offered with either an instantaneous +/-10V voltage output (-SB models) or with a DC true RMS 0 to 20mA current output (-SRI models)

Isolated surface-mount current transducer family
LEM has introduced the HMS isolated surface-mount current transducer family which operates from a single +5V supply and is designed for use with open-loop Hall-effect technology.
Current transducers operate from single 5V supply
The HASS series of LEM's range of current transducers designed to operate from a single +5V power supply has been added to its repertoire.
These versions incorporate signal conditioning, making them suitable for use with programmable logic controllers (PLCs).
The use of open-loop Hall effect technology allows the transducers to measure DC, AC and pulse currents and provides galvanic isolation between the primary and output circuits.
Their clearance and creepage distances provide a test isolation voltage of 12kVRMS/50Hz/1min.
This technology also offers low power consumption.
The HAZ series transducers conform to the EN 50178 standard, use UL94-V0 recognised materials and are CE marked according to the European Directive 89/336/EEC.
They are particularly suitable for industrial applications, including high current rectifiers, uninterruptible power supplies, power supplies for welding, battery-powered applications, telecom applications and also DC switchgear in traction applications.
Additional models in the family, scheduled to be introduced later this year, will offer a range of output signal conditioning, including 4-20mA, 0-20mA or 10V signals, all available in DC true RMS, instantaneous, or average RMS value.
The HAZ transducers are covered by a five-year warranty.
