MOSFET on voltage drop in the ON state, as well as on offset voltage
at the evaporator in OFF state.
s
Electronic reverse polarity protection for the electronics and mechanical
reverse polarity protection by a new battery cover that prevents imme-
diate and lasting steaming in reverse polarity! This combination deve-
loped by us makes the rare case of reverse polarity as safe as possible
WITHOUT impacting the normal operation (volt-drop / efficiency).
TECHNICAL DATA
Warning: Use only batteries suitable for your coil!
The max. current, the battery needs to supply, is calculated as follows:
Imax = 4.25 / Rcoil. E.G.:
s6
Ω
= 4.25A
s6
Ω
= 21.25A
s6
Ω
= 42.5A (Risk of damaging the PCB)
Sample calculations of coil resistance and the power range
of a conventional battery:
battery voltage (fully charged) of 4.2V ; Coil with 1
Ω
=> 4.2V / 1
Ω
= 4.2A => 4.2V * 4.2A = 17.6W
battery voltage (empty) of 3.0V ; coil resistance of 1
Ω
=> 3.0V / 1
Ω
= 3.0A => 3.0V * 3.0A = 9.0W
