Now it's my turn to ask couple of questions .....
( mainly to the brothers : SupraSPL -Guod -Mr Flux ,but if anyone else knows anything about ,please feel welcome to respond ...)
I got the MeanWell
HLP-80-42 for driving the
CXA3070 ...
http://www.meanwell.com/search/HLP-80H/default.htm
I was notified-just-yesterday about a shop that has 'em in stock for ~$40 each :
http://www.kutop.com/80w-meanwell-hlp-80h-single-output-dimmable-led-driver.html
That driver has two trim pots ..
One is to adjust (limit in fact ) the output current ..( 1.56 -1.95 A )
And the other trim pot adjusts output voltage (? ) (38-46 V )
While it can provide CC regulation from 25.2 V up to 42 V (output voltage )
This driver can operate both as a CV or as a CC driver ...
I'm pretty sure that this driver in fact ( HLP-80H -42) ,is the bare 'internal' pcb of the top series
HGL-80H-42,which has almost double retail price !
From HGL-80H-42 :
Can somebody explain to me in which situation a CV of >42 V is needed ?
And what would be the current then ?
Does it mean ,that once the Vo is adjusted >42 V ,then the current adjust is being done throught the Io trim pot ?
And the driver works as a CC only when Vo max =42 V ?
Very interesting is also the test report of the driver :
Where actually the current range is 1.2 A to ~2.3 A !!!
As well as the dimming function test report ...(besides 'spec' is 'report ' ) ...
Where it shows ,that only when using a res/pot or PWM ,the driver goes well over 100% of Io ....
As also the user manual ....(besides 'certificates'
Where it says,about appropriate circuit breakers ...
( also another 'hint' that HLP series is the bare pcb of the HGL series ...)
So for my fixture ,which utilises 4x of these drivers ,I should use either a 'B' type circuit breaker at 16 A ,
or a 'C' type circuit breaker at 10 A ..
Correct ?
( here's the 'tripping classes ' of circuit breakers .Common ,no matter the brand of the CB :
And that of course ,because of the ' inrush current ' of the drivers (
70 A ) :
https://en.wikipedia.org/wiki/Inrush_current
While the 4 drivers will only draw 4* .4 A =1.6 A when in normal operation ,
when powered on ,for a brief moment ,inrush current is 63 A ! ....
So ...
Would be this resettable CB appropriate for my fixture ?
