Low-Voltage Output Terminal: Temperature Range -40°C to +105°C

Q: What is the primary function of a low-voltage output terminal in voltage measurement?

It provides a safe and reliable connection point for measurement instruments to access the divided voltage signal while maintaining electrical isolation from high-voltage sections.

Q: Can these terminals be used in outdoor industrial environments?

Standard versions are for indoor use (IP20), but IP67-rated versions with enhanced sealing are available for outdoor or harsh environments.

Q: What maintenance is required for these terminals?

Periodic inspection for corrosion, verification of tightness (recommended torque: 0.5-0.8Nm), and cleaning of contact surfaces with appropriate electrical contact cleaner.

Component Specifications

Definition

A specialized electrical terminal designed to safely and accurately output low-voltage signals from voltage measurement divider circuits in industrial equipment. It provides secure connection points for measurement instruments, control systems, or monitoring devices while maintaining signal integrity and electrical isolation.

Working Principle

The terminal provides a physical and electrical interface between the voltage divider's output and external measurement equipment. It maintains the divided voltage ratio by minimizing contact resistance and preventing signal degradation through proper material selection and mechanical design. The terminal ensures electrical isolation from high-voltage sections while providing reliable low-voltage output.
