CLAMPING / CROWBAR characteristics CLAMPING CROWBAR I I IPP , / CROWBAR COMPARISON ­ The CLAMPING devices suppress all overvoltages reaching the knee of the curve (VBR). During the surge suppression the working point is defined by the couple IPP, VCL. ­ The CROWBAR devices , point is defined by the couple IPP, VT.

2000 - fuse thyristor

Abstract: No abstract text available
Text: : Overvoltage at the output may damage the power supply! Crowbar Switching regulators (except PSR, PSA) can be provided with a thyristor crowbar. (Option C) The thyristor crowbar acts as a protection against internally , currents. The current rating of a thyristor crowbar is limited, e.g.: ISC = 8 A PSB case B02 PSC, PSL case , PSS units, when the crowbar option is used with two or more power supplies in parallel, all crowbar trigger terminals (C) should be interconnected. This ensures all crowbar circuits trigger simultaneously
