HAS600-S/SP50 Key Technical Specifications

Why Choose the HAS600-S/SP50?

Swiss Quality – Precision and Reliability

As the global benchmark in electrical sensors, LEM has spent decades perfecting Hall effect measurement technology, with products widely used in rail transportation, industrial automation, and new energy. The HAS600-S/SP50 continues LEM’s tradition of excellence. It meets UL 94-V0 flame-retardant plastic housing standards and is CE and RoHS certified.

Accurate Current Measurement – Protect Your Core Systems

Based on the proven Hall effect open-loop principle, the HAS600-S/SP50 provides full electrical isolation between the primary (high power) and secondary (electronic) circuits. With an accuracy of ±1% FS and a total error below 1% (linearity error also within 1%), it reliably measures DC, AC, and pulse currents, delivering true, stable data to your control system.

Real-world example: a PV inverter manufacturer reported that after adopting the HAS600-S/SP50, DC side current sampling error dropped from 1.2% to 0.3%, boosting estimated annual energy yield by 2.8%.

In a 1000 V DC system, the sensor’s temperature drift is only 0.02%/K over -40℃ to +85℃, showing excellent thermal stability.

Wide Measuring Range & Fast Response

The HAS600-S/SP50 has a rated current of 600 A and can measure up to 900 A, handling everything from light load to overload conditions. Its response time is about 3 μs, and the bandwidth covers DC to 50 kHz, enabling accurate capture of highfrequency current fluctuations – essential for drive controls and servo systems.

Excellent Insulation – System Safety First

Safety is paramount in high-voltage environments. The HAS600-S/SP50 offers an insulation test voltage of 3300 V, insulation resistance >1000 MΩ (@500 VDC), a basic insulation voltage rating of 600 V, and reinforced insulation rating of 300 V. Superior electrical isolation helps prevent leakage risks, protecting both equipment and operators.

Low Power Consumption – Green & Efficient

With a current consumption of only ±15 mA, the HAS600-S/SP50 places a very low burden on your system’s power supply, improving overall energy efficiency – a key advantage in today’s energy-conscious world.

Easy Installation – Plug & Play

The sensor features a panel-mount design, is compact, and weighs only about 60 g. It is designed for use with Molex connectors (housing 511910400, contacts 508029101). For engineers focused on development speed and cost control, the HAS600-S/SP50 offers high performance combined with ease of use.
