Current Transducer Offers Current Output

Feb 26, 2008 11:24 AM

Additions to the LEM’s LTS family of +5-V current transducers, the LTSP current transducer measures positive and negative ac, dc and pulse currents on pc boards and provides a current output instead of the voltage output provided by the other units in the family. This allows the LTSP to detect currents up to at least 14 times the nominal current.

Device type: +5-V current transducer
Features: closed-loop multirange current transducer using the Hall effect; multi-range configuration is designed for nominal currents of 8 A, 12 A and 25 Arms; galvanic isolation between the primary and output circuits; access to the internal 2.5-V reference
Operating temperature range:-40ºC to 85ºC
Packaging: 22.2 mm (L) x 10 mm (W) x 24 mm (H)
Target applications: ac variable speed and servo motor drives, static converters for dc motor drives, battery-powered applications, switched-mode power supplies, UPSs, and welding power supplies
Approvals: CE marked, UL recognized, conforms to the EN 50178 standard for industrial applications
Pricing: $17.55 each
Availability: available now

Notes: The LTSP uses the same ASIC as LEM’s LTS and LTSR models.
