Variable multiturn wire-woundresistors with rotary system driven by worm gear. (40 turns from minimum to maximum)
Basic technical characteristics of resistors SP5-2:
SP5-2 resistors are designed for operation in DC and AC circuits.
nominal resistance range, Ohm – 100-330
Max. operating voltage, V - 300
Tolerance ,% - 1,0 (up to 1000 Ohm)
Nominal power, W – 1
Equivalent rotation noise resistance – 500 Ohm
The intermediate values of the rated resistances correspond to the E6 series with tolerances of ± 5%
Critical operating conditions:
Ambient temperature:
at rated electrical load - -60 to +70 ° С
with a decrease in the electrical load to 0.1 - from -60 to + 125 ° С
Relative air humidity at a temperature of 35 ° C - up to 98%
Low atmospheric pressure: up to 667 Pa (5 mm Hg)
Durability - 100 cycles
The moment of static friction of the rotary system - from 0,49 to 19,6 mN · m
(from 5 to 200 g · cm)
Minimum operating time: 2,000 h
