The SV241 device's input is rated at 10A maximum current (and some users' power supplies may have a lower rating).
Since the SV241 has a current sensor, I suggest adding the following functionality:
-
Current Limiting for Heater Output: If the total input current approaches 10A (or a lower, user-specified value), the heater output power should be automatically reduced to ensure the current does not exceed the maximum permitted limit. It is certainly less critical for the dew heaters to operate at reduced power than for the entire device to fail due to a blown fuse or triggering a hard over-current protection mechanism.
-
Cascading Output Shutdown (Over-Current Protection): As a second step (especially for users of unregulated dew heaters), it would be beneficial if the device would switch outputs (12V, regulated, and USB outputs) off in a user-specified priority order if the current exceeds the maximum allowed limit.
