rectifier bridge

The bridge rectifier is suitable for UL1557 certification.

UL1557 it is a device for electrically isolated semiconductor devices. UL( Underwriters Laboratories) Certification standards, mainly applicable to isolated installation type semiconductor devices, such as thyristors, transistors, diodes, etc., and hybrid modules composed of a combination of these devices.

UL1577 the standard covers the isolation performance of thyristors, transistors, diodes, etc., and their performance in relation to module combination schemes and structural characteristics.

Rectifier bridge, as a device composed of multiple semiconductor diodes, also belongs to the scope of application of UL1557 standard. It should be noted, however, that UL 1557 does not apply to the particular combination of damper and rectifier circuits with thyristors, transistors, or other analog semiconductor devices.

When applying for UL1557 certification, manufacturers can entrust Ankor to submit detailed product design and manufacturing information, as well as samples for UL testing and evaluation. The test may include withstand voltage test after high and low temperature aging to evaluate the safety of the rectifier bridge.

If the product passes the test and meets the requirements of the UL1557 standard, the manufacturer can obtain the UL certification and mark, which proves that its product has met the internationally recognized electrical safety standards.
