What you can do

Draw your single-line diagram. Pick a fault location. Run the simulation. You get clear answers to the three questions that decide whether a DC design is safe:

  • Can each protection device interrupt the fault current it would see?
  • Does the closest device trip first, so a fault stays contained? (selectivity)
  • Does the bus voltage stay within ride-through limits after the fault?

Results land on your diagram. Hover over any component to see peak current, let-through energy, and voltage. No spreadsheets. No separate software. No waiting on an outside study.

Why it matters for LVDC

Short-circuit protection for low-voltage DC has been hard to design. Existing standards do not fully cover it. IEC 61660, for example, was not written for DC/DC converters or for bus voltages that shift in the moments after a fault. DCIDE is built for what those standards miss.

The stakes are real. A protection scheme that looks right on paper can still fail to clear a fault.

A platform, with experts behind it

DCIDE is more than advanced simulation. Behind the platform is a team of DC power engineers. Ask a question inside any project and a real engineer answers, someone who designs DC systems for a living. You run the simulations. We back you up.

The payoff

  • Design DC protection with confidence, grounded in simulation.
  • Move faster from design to quote. The analysis lives with the design.
  • Keep your whole team on one shared, current view of the system.
  • Get expert help the moment you need it, without leaving the project.

Run your first fault simulation

Open the OCP 800 V reference design, duplicate it, and run a fault simulation on your own version.
