Product Description
LEM DHR 500 C420 is a high-precision current transformer from the DHR series, engineered to measure electrical currents up to 500 amperes. Supporting a supply voltage of 20 V and 50 V DC, it ensures accurate current and voltage output signals suitable for modern variable frequency drives (VFD) and silicon controlled rectifier (SCR) applications.
The device operates efficiently in a temperature range from -40°C to 100°C and can handle frequencies up to 6000 Hz, making it ideal for demanding industrial, electrical automation, and process control environments. Its panel mount design with a 32 mm bore diameter allows easy integration and cable access in control panels.
Measuring just 90 mm in width and 25 mm in depth, the compact current transformer is designed for simple installation with electrical isolation to prevent excess losses and ensure safety in measurements. The LEM DHR series transformer provides reliable output voltage or current signals based on actual current flow, enhancing the accuracy of process measurements.
