The recommended wiring configuration for the 37020 is a 3-wire connection: one wire for the voltage input, one wire for the current input, and one wire for the ground connection. Refer to the Simpson Electric application notes for specific wiring diagrams and guidelines.
The 37020 has an accuracy of ±1% of full scale for voltage measurement and ±2% of full scale for current measurement. This accuracy is specified for a temperature range of 23°C ±5°C and may vary slightly outside this range.
The response time of the 37020 is typically less than 100 ms for voltage measurement and less than 50 ms for current measurement. This response time is dependent on the input signal frequency and amplitude.
The 37020 is rated for operation in temperatures ranging from -20°C to 60°C. While it can tolerate short-term excursions up to 85°C, prolonged exposure to high temperatures may affect its accuracy and reliability. Consult Simpson Electric for specific guidance on high-temperature applications.
The 37020 is not inherently suitable for use in hazardous locations. However, it can be used in hazardous locations if installed in accordance with the relevant safety standards and regulations, such as UL, CSA, or ATEX. Consult Simpson Electric for specific guidance on hazardous location applications.
