TELCON HALL EFFECT CURRENT SENSORS 5 HTP Range - PCB Mounting Our HTP range of products are PCB mounted units covering the range from 10A to 230A. The HTP50 range is designed for use with a cable for the primary current, but busbars are available up to 150A for PCB primary current connection. The HTPxxNP, HTPxxCPT and HTPxxM ranges all have PCB primary current connections as standard in various formats. HTM Range - Panel Mounted HT Range - Panel Mounted The HTx00M range are panel mounted units covering the range 200A to 1000A in two sizes. Industry standard connectors are offered but Fast- on or cable terminations are also available. Bus- bars and clamps are available as extras for this range. The HT range were the original Telcon panel mounted Hall Effect Current Sensors covering the range 100A to 300A. These are not recommended for new designs but are still available. HTPMLx Range - PCB Mounting - + 5V Supply The HTPxxMLV and HTPxxMLR covers the range 10A to 50A and operate from a single + 5V supply. Both types provide a voltage output centred on 2.5V. The HTPxxMLR has an additional 2.5V reference voltage output for use by the customer. HTP - PCB Mounting - Single Supply The HTP25MSV, HTP50MSV and HTP50SV are additions to the standard range and are designed for unidirectional current measurement and require a single + 15V power supply. HTPLP - PCB Mounting - Low Profile The HTP50LP is a development of the HTPxxNP range but intended for applications requiring a low unit height. The HTP50LP is only 11.3mm high off the PCB. Performance is similar to the standard HTPxxNP range. CLOSED LOOP RANGE
