Frequently asked questions

What heatsealing bands are suitable for this controller?

Bands must have a positive minimum temperature coefficient, such as Alloy-20 (TCR = 1100 ppm/K) or NOREX (TCR = 3500 ppm/K).

Is an impulse transformer required?

Yes, a suitable impulse transformer designed according to VDE 0570/ EN 61558 with a one section bobbin is necessary.

What current transformers are compatible?

Only the original ROPEX PEX-W2 or PEX-W3 current transformer may be used.
