The BC-1 wire wound resistor has high resolution ability. The range of resistance value is wide, heat resistance, humidity resistance, wear resistance and other characteristics,Suitable for the voltage and current adjustment of the power equipment and circuit that does not exceed 380V and the DC does notexceed 220V.
Technical parameters of BC1 -type rotor rotor resistance:
1. Extreme work voltage of the resistor: 1000V: an insulation voltage 2500V 2. The temperature rise of the barrier: 25-100W variety ≤300K; ≥150W variety: ≤350K 3. Sliding itinerary: 25-50W variety: 280 ± 5 °; ≥100W variety: 300 ± 5 ° 4. Law of law blocking, linear deviation: In the entire itinerary, the rhythmic block changes to a straight line, and the linear deviation is not greater than ± 10% 5. The transformer control shaft rotates 5,000 weeks within a itinerary of not less than 90%. 6. The transformer with a high temperature of 40 ° C is 6 weeks (six days), and the insulation resistance is less than1.5mΩ
product description:
The BC1 series of rotor -arm sliding wire porcelain disk variants are suitable for voltage, current adjustment, and cross -current electric motor speed adjustment in industrial electrical equipment with a voltage of no more than 500 volts. The barrier is used as a resistance material to the round ceramics skeleton by the Kang copper line or nickel chromium wire. The resistance materials are coated with high temperature enamel coatings and bonded on the ceramics chassis except for sliding contact surface. The sliding of the grip and brush to obtain the resistance value of the change. The variable resistor is separated and protected. Its protective type is the barrier plus metal protective box shell, which is equipped with a handwheel.
