ADDITIONAL TAPPINGS
Are supplied with their adjustable collars fastened but not set to any specific value. Please note that, on request, all tappings can
be adjusted by VISHAY SFERNICE. For adjustment purposes we would need to be advised of the ohmic values, and tolerances
of the sections in successive order in addition to their sum Rn.
The permissible maximum value for an adjustment should take into account the possible negative tolerance of Rn.
Please consult VISHAY SFERNICE regarding the acceptable tolerance.
RECOMMENDATIONS FOR USE
Maximum Current Strength:
The ohmic value and the power decrease as the connections are brought together. To avoid overload, the maximum current
strength that is permissible for Rn should never be exceeded:
