Custom Panel

Custom Panel

In case you're wondering: Sure! We can get you a custom coloured front panel for the ADDAC303.
It has an additional cost and takes 4 to 6 weeks to be ready.

At the moment we have standard issue stock for either Black or Red panels for this module

A custom colour panel can be done in either Green, Blue, White, Silver Gray, Yellowed Silver, and Dark or Light Bronze.

Print colour varies between Black, White, or Red, Blue and Green. We recommend lighter-tone print for darker panels, and vice-versa.

Please note: we don’t stock custom coloured panels. For every custom order we need to make a single panel order from our panel provider. This explains the panel price and lead time.

Prices shown exclude VAT, outside EU all orders are VAT free.
