A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Dengrove offers reference design for rail surge protection
The R-REF04-RIA12-1 board targets high-voltage applications up to 110V and the R-REF04-RIA12-2 is intended for DC input current up to 10A. Both are input-side fused and can be used with single-output DC/DC converters up to 45A. The boards feature a universal pinout for 2.0 x 1.0 (50 x 24mm) quarter-brick and half-brick standard case sizes. Users can choose from converters of power ratings up to 240W, says Dengrove Electronic Components.

 

RIA12 surge protection is via an active input-voltage clamp featuring a surge-stopper IC, which acts quickly to block surge voltages up to 385V DC. The clamp circuit also provides in-rush current limiting. The boards provide a nominal value of hold-up capacitance, with connectors to add extra capacitance if required. The input, output, and hold-up connections feature cage-clamp terminals and there are isolated connections for fan power and system-enable.

The distributor stocks the reference boards and a selection of applicable Recom DC/DC converters. The specialist distributor can also advise customers on selection for projects.
