Important Technical Note

The stated secondary values of 24 V and 8.25 A mathematically correspond to a power of approximately 198 VA and therefore do not match the stated rated power of 150 VA.

At a power of 150 VA and a secondary voltage of 24 V, the calculated secondary current would be approximately 6.25 A. However, this value is not confirmed and must not be used as a connection value without verification.

Please check the specifications directly on the nameplate before ordering and commissioning.
