FAQ

To choose the right input fuse for a dc-dc converter, you need to take into account various factors. These include the converter's voltage and current ratings, its interrupting and temperature derating capabilities, the melting integral or I2t, the maximum fault current of the circuit, and the necessary agency approvals. You should also consider mechanical aspects such as the fuse's size, mountability, and accessibility.

The primary distinction between the AC and DC ratings of a fuse lies in their capacity to interrupt the electrical arcs that occur when the fuse blows. DC arcs are comparatively more difficult to interrupt than AC arcs, necessitating fuses that are rated for lower voltages, frequently 32VDC.

It is not safe to use DC and AC fuses interchangeably.

The voltage rating of a fuse is crucial and must not be overlooked. It is essential to ensure that the chosen fuse's voltage rating is higher or equal to the circuit voltage to prevent any electrical hazards. The voltage rating becomes highly significant when the fuse tries to open due to its low resistance.

CHYT DC fuse is generally are rated 1000VDC, 1500VDC.
