Resistors PPB(ППБ) – variable wire frameless adjusting resistors, potentiometers , with a power of up to 50 W with a linear dependence of A and an adjustment range of 2.2 Ohm to 47 kOhm . PPB resistors are single-turn resistors with circular movement of the moving system. Resistance tolerance ±5% and ±10% . Resistors have acceptance “OTK” and “PZ”. The working elevated temperature of the medium does not exceed +155°C , the lower one – up to -60°C . Wear resistance – up to 5,000 cycles of slider movement. Variable resistors PPB are resistant to vibration loads in the frequency range of 1-2000 Hz (acceleration amplitude up to 73.6 m/s 2 ), single mechanical shocks (acceleration up to 1471 m/s 2 ) and multiple actions (acceleration up to 343 m/s 2 ) . Designed for operation in DC or AC circuits (frequency up to 1000 Hz), providing current limiting and voltage distribution.
