Component Specifications

Definition
A voltage divider/sensing network is a passive linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin). In industrial voltage feedback sensors, it precisely scales high-voltage signals to measurable levels for monitoring, control, and protection systems, ensuring accurate voltage representation for microcontrollers or analog circuits.
Working Principle
Operates on Ohm's Law and the voltage divider rule: Vout = Vin × (R2/(R1+R2)), where R1 and R2 are resistors in series. It attenuates input voltage proportionally based on resistor ratios, providing a scaled-down, isolated signal for safe and precise measurement by downstream electronics.
Materials
High-precision metal film resistors (e.g., 1% tolerance, low TCR), ceramic or PCB substrate, copper traces, protective conformal coating, and terminal connectors.
Technical Parameters
  • Accuracy ±0.5%
  • Power Rating 0.25W to 2W per resistor
  • Isolation Voltage Up to 2500V
  • Resistance Values Customizable (e.g., 1kΩ to 10MΩ)
  • Temperature Range -40°C to +125°C
  • Input Voltage Range 0-1000V DC/AC
  • Output Voltage Range 0-5V or 0-10V
Standards
ISO 9001, IEC 61010-1, DIN EN 61326
