ITPS and PW-70 or OPUS?
How do I know if I need a ITPS and PW-70 or and OPUS PSU?
what is the pros and cons of both setup, if any difference?
In my opinion, the Opus is the only way to go.
The PW70 doesn't regulate the voltage. The ITPS does, however it has a 1.3V dropout. Which means you need to pump at least 13.3V into the ITPS to get 12V out the other end. When your car is off...it won't give out that power.
The Opus takes voltages from 8-18V, has the startup/shutdown controller, regulation, more power (the ITPS will only output 60W if it's regulating), and it's one individual unit, designed for the job, rather than two seperates hacked together to do a similar job.
Go for the Opus, you won't be disappointed.
pricewise, is it similar? (I haven't found the price on the OPUS website)
and what about the dashPC circuit?
this seams to be interesting...
anyway, thanks for the input. It really helps.
