LEM released three HO-series, high-performance current transducers which extend nominal current measurement up to 250 A and come in PCB, panel or busbar mounting.
The transducers measure DC, AC and pulsed signals using the latest generation of LEM’s open-loop Hall effect ASIC. They exhibit offset and gain drifts which are up to twice as accurate across the temperature range as the previous generation and have a faster response time of 2,5 to 3,5 μs.
Operating from a single supply voltage of 3,3 V or 5 V, the HO series can measure up to 2,5 times the primary nominal current and includes an additional pin which provides over-current detection set at 2,93 times the nominal current IPN (peak value). Fault reporting is also provided in the event of memory corruption.
Extended clearance and creepage distances of more than 8 mm, together with a comparative tracking index (CTI) of 600, mean that, despite small packages of 22,95 cc to 33,15 cc, there is no compromise on the insulation level provided between the primary and measurement circuits.
The range of options offered by HO transducers makes them suitable for a wide selection of applications, including solar combiner boxes and solar power inverters, small smart meters, variable speed drives, uninterruptible and switch-mode power supplies, air conditioning, home appliances, static converters for DC motor drives, and robotics.
A wide operating temperature range of -40°C to +105°C also makes the HO series suitable for use in any industrial application. The transducers are CE marked and conform to the EN 50178 standard as well as being covered by a five-year warranty.
