ꢀ Widest range in the industry!
ꢀ High thermal capacity & power-to-size ratio
ꢀ Highest power performance for low cost
ꢀ Flameproof silicone coating
High power edgewound construction, economical price!
RCD Series EW is designed to meet heavy-duty requirements
where space is at a premium. Unique ribbon element is
edgewound onto a ceramic tube offering the industry’s highest
power ratings at a low cost. Inductance levels are lower than
conventional round-wire designs. Series EW is ideally suited for
load testing, power distribution, high power instrumentation, etc.
ꢀ Custom sizes and terminations available
