DESCRIPTION

ACxx-CS wirewound safety resistor series is designed to be

used as fusible safety resistor (or, AC mains input resistors).

It uses specially selected resistive winding wire and special

inflammable silicon cement coating material to ensure safe

and silent fusing operation in overload conditions.

The resistor fuses “without a bang” when AC mains voltage

is applied. At the same time, it acts as an in-rush current

limiting resistor for the normal operation.

The specially developed lacquer coating has superior

thermal and electrical insulating properties. This allows

designers to more easily meet the requirements of safety

approval, whilst eliminating the need to put additional fuses

in series with the input resistor.

Production is strictly controlled and follows an extensive set

of instructions established for reproducibility. Plated steel

termination caps are firmly pressed on the ceramic rods.

Connecting wires of electrolytic copper plated with 100 %

pure tin are welded to the termination caps. Suitable

resistive wire is selected as a winding material. An optimized

number of windings are wound on a high grade ceramic

body. The resistor elements are covered by a green

protective coating designed for electrical, mechanical and

climatic protection. The special coating provides ideal and

silent fusing of the component in overload condition, without

burning or explosion.

The ohmic value, tolerance, rated dissipation is stamp

marked. Also “S” is marked for safety version and “4S” and

“6S” is marked for AC05-CS 4 kV and 6 kV version

respectively.

The result of the determined production is verified by an

extensive testing procedure performed on 100 % of the

individual resistors. Only accepted products are stuck

directly on the adhesive tapes in accordance with

IEC 60286-1.

ASSEMBLY

The resistors are suitable for processing on automatic

insertion equipment and cutting and bending machines.

Excellent solderability is proven, even after extended

storage. They are suitable for automatic soldering using

wave or dipping.

The resistors are completely lead (Pb)-free, the pure tin

plating provides compatibility with lead (Pb)-free and

lead-containing soldering processes. The immunity of the

plating against tin whisker growth, in compliance with

IEC 60068-2-82, has been proven under extensive testing.

The encapsulant is resistant to cleaning solvent specified in

applied, shall be qualified by appropriate means to ensure

the long-term stability of the whole system.

APPROVALS

These resistors (AC03-CS and AC05-CS) have UL1412

approval (UL file no. E362452).
