Product Overview
The LEM HAS 50...600-P is a current transducer designed for the electronic measurement of DC, AC, and pulsed currents with galvanic separation between the primary and secondary circuits. It features an insulating plastic case made of UL 94-V0 recognized polycarbonate PBT, offering easy mounting, low power consumption, and a small, space-saving design. This transducer is ideal for applications requiring high immunity to external interference and a wide current rating range from a single design. It is suitable for industrial applications including AC variable speed drives, static converters for DC motor drives, battery-supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), and power supplies for welding applications.

Safety Notes
- This transducer must be used in limited-energy secondary circuits according to IEC 61010-1.
- This transducer must be used in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the manufacturers operating instructions.
- Caution, risk of electrical shock: When operating the transducer, certain parts of the module can carry hazardous voltage (eg. primary busbar, power supply). Ignoring this warning can lead to injury and/or cause serious damage.
- This transducer is a build-in device, whose conducting parts must be inaccessible after installation. A protective housing or additional shield could be used.
- Main supply must be able to be disconnected.
