Ερ: What are the measured data transfer rates (read, write)? Screenshot welcome.

Sharmman Sorry but totally inaccurate , speed of transferring a monolithic file like video of 2-10Gb was only 42Mb per Sec !

Ερ: Can clamp meter read the current in mA? whats the range?

Ερώτηση από BG523251711 επί 2021-10-29 10:26:25

Sharmman It shows 0.01A screen indication , set zero and you can measure from 50mA but its accurate from 0.5A

Ερ: what is the voltage output?

Ερώτηση από BG450345553 επί 2021-06-13 20:29:45

Sharmman At100% of Max power , output voltage = input voltage if current is less that 5A else Vout is < Vin.

Sharmman It's real for sure but the usage is strictly professional for people that need one degree angle spot with zero spill , something like a wider laser , definitely not for walking and targets lower than 100m since you can see only hot spot.I use it with tripod and my Coolpix 1000 zoom camera due to capture things in pure dark over 1 Km.

Sharmman Latest flux of Cree XHP50.2 3V can provide over 4500 Lumen at 14A , so 3X14=42A and 13,500 Lm (without optics) and even the strongest 21700 30T can't exceed 30A if wiring of direct 1mR mosfet is ≤ AWG14 plus spring by-pass.As I finally discovered , this can't exceed 6500 Lumen due to very thin leds wires and mosfet loss.

Sharmman It's a hard switching SMPS and independently of low ripple output , even working in the same floor with receivers and antennas , 160m,80m,40m bands will be seriously affected from transformer harmonics transmission , it won't affect bands over 6m though. Low frequency transformers (50-60Hz) are highly recommended for HF ham radio stations.
