The Difference between C-Tick and the RCM Mark

C-Tick and RCM Mark

There have been some recent changes to Australia’s regulatory regime when it comes to EMC compliance and electrical safety.

The introduction of the new RCM mark has caused some confusion, especially around what is happening with C-Tick.






First of all let us clarify what C-Tick is not.

C-Tick is not an electrical safety approval mark. It is purely an EMC compliance mark.

All power supplies sold in Australia must conform to Australia’s EMC regulations, as laid down by the Australian Media and Communications Authority (ACMA). ACMA is a Federal Government agency.

Next we need to touch on the Australian electrical safety regulations that apply to power supplies.

Some types of power supplies are classed by the Australian authorities as ‘in-scope’ or ‘prescribed’ electrical equipment. This means they must be tested and certified by a recognised body.

When it comes to Mean Well power supplies the products that usually fall into this category are:

Mean Well HLG-150H

Mean Well GST18A

Mean Well PB-600














All other power supplies in the Mean Well range are classed as ‘non-prescribed’ items. Although they don’t need to be tested and certified by a recognised body, the importer still has to satisfy themselves that they are safe.

RCM Mark





Up until recently ‘prescribed’ power supplies needed to show both a C-Tick and an electrical safety approval number. In an attempt to simplify matters a new combined Regulatory Compliance Mark has been introduced; the RCM mark.

On a ‘prescribed’ power supply the RCM mark replaces the C-Tick and the electrical safety approval number. The power supply in question is listed on the government ERAC website. The listing shows who owns the safety certificate and which models it applies to.

Certain ‘Non-prescribed’ power supplies will also show the RCM mark in place of the C-Tick. These too are listed on the ERAC website, but are marked as ‘non-prescribed’.

The RCM mark came into force in March this year. However, New South Wales has yet to participate in this new scheme, so there will still be power supplies sold that carry the C-Tick and electrical safety approval numbers.

Hopefully we have clarified the position on C-Tick and the RCM mark. However, if you have any question about approvals and Mean Well power supplies, please do not hesitate to speak to a member of our team.
