Beijing, China, June 9, 2019- LemElectronics, a leading global manufacturer of current and voltage measurement components, recently launched the HTT series current sensors with printed circuit boards installed, which allow devices to measure three types of current installations through a single printed circuit board. The maximum measurement current range of the new sensor is 25 to 150 arms, and it can monitor the three-phase current passing through a device with an installation area of only 16.8cm2 and a height of 29mm.

The HTT sensor has three 12 x 10 mm holes for connecting primary conductors and is secured by four metal pins that are soldered to the printed circuit board. The secondary connection of the power supply (0 V and three voltage outputs) is also connected to the printed circuit board through metal pins.

The HTT series offers five different types of sensors in the same housing, which can be used with± Use together. 12 to± 15 V bipolar power supply, capable of measuring nominal currents of 3x 25, 50, 75, 100, or 150 arms. At a test isolation voltage of 2.5kvrms/50 Hz per minute, open-loop Hall effect technology can measure DC, AC, or pulse currents and provide current isolation between the main circuit and the output circuit.

The Htt sensor complies with the en50178 standard and CE certification of European Directive 2004/108/EEC. These sensors are particularly suitable for industrial applications and household appliances, such as variable speed drives, uninterruptible power supplies (UPS), switch mode power supplies (SMPS), and air conditioners. The Htt series sensors come with a five-year warranty period.

The ITL 4000-s uses a bipolar+/-24 V power supply and can generate analog current output. It is applicable to all industrial applications that comply with the EN50178 industrial standard. In addition, current sensors are particularly suitable for controlling direct current in transformers or offshore wind turbines through direct current transmission, or measuring leakage current in any situation with high primary current.
