FJ31 DC Voltage Divider Product Description
The FJ31 DC voltage divider is a precision measurement instrument based on the principle of resistive voltage division, primarily used to extend the measurement range of DC potentiometers or serve as a voltage divider in DC circuits within rated voltage limits. Featuring a fixed-resistance input structure, it achieves voltage ratio conversion through precision wire-wound resistor chains, offering four selectable ratios: ×10, ×100, ×200, and ×500. The device incorporates high-quality resistance alloy materials manufactured with traditional techniques, demonstrating notable characteristics including operational reliability, minimal temperature drift, and excellent heat dissipation. With a rated input voltage of 600V and power consumption of 1W, it maintains stable performance under environmental conditions of 10℃~30℃ and humidity ≤80%. The switch-based conversion mechanism ensures user-friendly operation, housed in a compact 260×195×130mm enclosure weighing approximately 3kg. This equipment is suitable for scientific research and industrial applications requiring high-precision DC voltage measurements. 349
