LEM has introduced the LA 130-150 series of current transducers for use in motor drives, inverters, power supplies and general industrial applications.
The PCB-mounted devices will measure nominal full-scale currents of 130 and 150A (rms).
The LA 130-150 series measures DC, AC, and pulsed currents, providing an output in the form of a current signal proportional to the measured (primary) current.
Two conversion ranges, a factor of 1000 or 2000, are offered, with two mounting styles; the transducers can be supplied with an open aperture through which the current carrying the primary current is routed: or they can be supplied ready-fitted with a primary conductor that will connect direct to the host PCB.
Within the 33.5(H) x 37(W) x 16(D)mm outline, the conductor aperture is a generous 13.5 x 10 mm. In form, footprint and function the LA 130-150 series is backward-compatible with LEM’s prior-generation devices.
The transducers have a maximum bandwidth of DC to 150kHz (-1dB point) and an accuracy of better than 0.5% at the primary nominal RMS current and at ambient temperature.
Typical linearity error is ±0.1% at nominal current and the maximum offset temperature drift is ±0.46% of nominal current from -40 to +85?C.
