Description
The BC1-W Bottomless Disc Variable Resistor is a chassis-free rotary adjustable wire wound resistor designed with a high-temperature ceramic substrate and precision resistance wire uniformly wound around the coil frame. A movable wiper slides smoothly along the winding to adjust resistance value. This series features high power rating, excellent heat resistance, stable performance, and a wide adjustable range.
BC1-W resistors are suitable for AC or DC circuits requiring adjustable load control, voltage regulation, current limiting, or testing applications. They are widely used in laboratory instruments, educational equipment, industrial control devices, and power electronics.
The BC1-W series is available in multiple power ratings from 50W to 500W, with corresponding structural dimensions to fit different installation needs. The products feature robust mechanical construction, reliable contact performance, and good durability during long-term repetitive adjustments.
Features
1. Power range: 50W / 100W / 150W / 200W / 300W / 500W.
2. Operating voltage: AC 600V, DC 500V; dielectric strength up to 2500V.
3. Temperature rise limit:
50–100W models ≤ 300K
≥150W models ≤ 350K
4. Smooth adjustment angle:
50W models: 280° ± 5°
≥100W models: 300° ± 5°
5. Resistance tolerance typically within ±10%.
6. Long mechanical life: ≥ 5000 cycles of effective adjustment.
7. Insulation resistance ≥ 1.5MΩ (tested at normal humidity and 40°C).
With their reliable performance and wide power range, BC1-W variable resistors provide an ideal solution for adjustable load, voltage, and current control in various industrial and educational applications.
