HOB 50-P

HOB 50-P is a current transducer for the electronic measurement of current: DC, AC, pulsed with galvanic separation between the primary and the secondary circuit. With a market-leading response time of <lt/> 200ns, compared to average response times of around 3microseconds, the HOB-P sensor is capable of measuring DC, AC or pulsed current up to 250A. At the same time, it is ideally suited to wide bandgap (WBG) power electronics use cases and applications that require enhanced immunity to the dv/dt (acceleration) issues that SiC power modules are prone to. Among those applications stand handheld plasma cutters, welders, DC-DC converters, etc. Suitable for industrial application domain. Complies with IEC 61010-1: 2017, IEC 61010-2-30: 2017, IEC 61800-3: 2017, IEC 61800-5-1: 2007, IEC 62109-1: 2010 and UL 508: 2018 standards.

• Primary nominal RMS current of 50A
• Open loop multi-range current transducer with voltage output
• High cut-off frequency up to 1MHz, enhanced immunity
• Ideal for harsh environments with operating temperature range from -40°C to +105°C
• Compact design for THT PCB mounting
• Lower noise and better dv/dt behaviour vs other classical O/L sensors from the market
• Low power consumption, level shifting, low offset temperature drift
• Single power supply +5V, creepage / clearance <gt/> 11mm, total error (ambient temp) <lt/> 1.45%
• Galvanic separation between primary and secondary circuit
• Factory calibrated

Avertismente

Never connect or disconnect the external power supply while the primary circuit is connected to live parts.

Note

Always wear protective clothing and gloves if hazardous live parts are present in the installation where the measurement is carried out.
