Hi all,
I've pointed something annoying with these 2 modules :
- Multisafer Vu (MV)
- Vico Power Plus (VPP)
Both have a voltage display, which helps to understand the problem.
I have 3 peripherals connected to MV or VPP :
- DR750S-2CH (400mA)
- Cowon AW1 (300mA)
- 4G Router (20mA)
For example, my battery voltage is 12.0V.
If I disconnect both dashcams, voltage on MV & VPP display is 12.0V.
That is OK
But, when I connect both dashcams,
- MV shows 11,7V
- VPP shows 11,5V
That is really a problem if you want to setup a voltage cutoff.
If I want a 12.0V cutoff, I should setup 11.7V on MV and 11.5V on VPP.
The second problem is that power output of the VPP is 1,2V less thant battery power.
So, when battery is 11.8V, the output power is 10.6V, which makes DR750S rebooting many times.
The output power of the MV is only 0.5V less than input power, which is acceptable and does not makes my DR750S rebooting.
