Common buyer questions
Can this model be customised?
Customisation depends on the electrical, mechanical and order requirements. We confirm feasible changes before quotation.
Are all certificates shown on the site included?
No. Documentation is checked against the exact model, configuration and destination before it is listed in the project file.
How do I start?
Send the application, voltage, power or current, runtime, size limit, quantity and destination. We will return the confirmation list.
Request a model-specific configuration
Add this reference model to the quote cart and include the real application. The reply will separate confirmed parameters from items that still need validation.
