Supply stands up to telecomms surge tests

Bear Power Supplies has tested its standard 15W encapsulated AC/DC convertor and found it to pass the high-voltage lightning surge tests as defined by the GR-1089 Standard for Telecom Equipment, Section 4.7: 'Lightning criteria for equipment interfacing with AC power port'. This test requires that the power supply continue operating during and after application of several 2000V surges on the AC power port, and survive a 6000V surge without becoming a safety hazard. A tech note detailing the test results is available from the Bear website.

Bear encapsulated power modules feature long life and high reliability over a wide -40 to +70C operating temperature range, making them ideal for outdoor telecomms equipment.

Standard models are available from 5 to 30W, with universal input (90 to 264V AC) and single output from 3.3 to 48V.

All Bear models are TUV tested to the EN6100-4 standard for surges.

Bear also designs and manufactures custom AC/DC and DC/DC power supplies for telecomms and other commercial, industrial and medical applications.
