2000VDC Industrial DC Resistance Box – Variable Resistor Tool
2000VDC Industrial-Grade DC Resistance Box
This 2000VDC Industrial-Grade DC Resistance Box is a precision electronic component designed for professionals, engineers, and educators who need a reliable, adjustable standard resistance source in DC circuits. Compact, sealed, and built from durable ABS material, it delivers accurate, traceable resistance values for circuit testing, instrument calibration, and laboratory experiments.
What Is a DC Resistance Box?
A DC resistance box is an electronic instrument that precisely outputs fixed or variable DC resistance values. It uses internally preset resistor units — such as metal film and wirewound resistors — combined through switching mechanisms to provide a known, stable resistance load or calibration reference for DC circuits.
Key Features
- High Voltage Rating: Supports up to 2000VDC between binding posts — ideal for industrial and high-voltage applications.
- Precision Accuracy: ±2% resistance accuracy at 23°C ± 5°C for dependable, repeatable results.
- Multiple Models Available: Choose from 1M, 10M, 100M, or 1000M configurations to match your project requirements.
- Sealed Compact Design: Measures just 64mm × 58mm × 35.5mm (excluding binding posts), making it easy to integrate into tight spaces or portable test setups.
- Wide Operating Range: Functions reliably from -40°C to 60°C and up to 80% relative humidity — suitable for demanding environments.
- ABS Housing: Lightweight, durable white ABS enclosure protects internal components.
- Standard Binding Posts: Ø13mm × 24mm posts with 40mm spacing; compatible with 4mm banana plugs and M6 stud connections.
Common Applications
- Circuit Testing & Debugging: Simulate known loads to verify DC power supply performance, test control circuit responses, and troubleshoot current/voltage anomalies by comparing theoretical and measured values.
- Instrument Calibration: Use as a standard resistance source to calibrate multimeters, ohmmeters, DC power supplies, and resistance testers for accurate measurement results.
- Teaching & Laboratory Experiments: Ideal for academic settings where repeatable, adjustable resistance values are needed for demonstrating Ohm's Law and other DC circuit principles.
