This is not a factor whether it is immersed or not, main motive is to fulfill my requirement
1) long last and there will not be no issue for such frequent operation with short duration of time.
Will Diaphragm Pumps or Peristaltic Pumps is best suitable for the application. Or anything else?
Thx
Hi,
Is there any excellent quality DC Submersible Pump?
which will be used for the operation of
hand sanitizer project and will turned on/off for frequent no of times (2000 times/day) for 2-3 sec.
If the above type is used for this purpose the life cycle of the pump will be a questionable...
Hi,
I want to use pcb relay to control(on/off) the submersible motor-pump of 5 hp with MCU control.
for that, efficiency = 85%, pf=80%, at 230v, the Continuous current(I) will be,
Input=o/p / efficieny = 5/0.85 = 5.8 ==6 hp x 746 =4.476 kw.
I= 4.476/(230x0.8) = 25A running current.
--As...
Hi all, I
I am using compiler CCS (v5.008) and MCU PIC18F46k22(has 2 MSSP module) , to display text in P10-DMD using MSSP2 module of the MCU.
---My target to use MSSP1 for hardware I2C (for RTC clock) and MSSP2 for hardware SPI (to display clock data in DMD).-----
For that, FIRST going to...
#7,
Yes, zener gets cold if total load is operated.
I am getting confused, let me clear first___________________
As I know here Zener is used to maintain constant voltage 5.1v - at NO LOAD and LOAD condition.
In my case,
At LOAD condition, maintained 5.1 and NOT GET HEATED----------OK.
But at...
STILL_Zener getting heat at no load in Capacitor power supply arrangement..
Tnx for reply..
I have calculated as u suggested #4. And calculatiob sheet and schematics are also here.
But still ZENER(5.1v/1.3 w) getting hotter with calculated Film cap(~2.5ufd) is used.
If 2.5ufd IS REPLACED WITH...
after putting series Resistsnce (Rs) in series with zener and o/p is taken out across zener, the same thing is happening (ie, at no load the zener as well as Rs GETTING HEATED.
AS PER MY CALCULATION,
1) Max current through zener= bener wattage/zener volt=1.3/5.1 = 0.255amp,
2)Min Value of Series...
Hi,
With this PS, trying to operate 2 relays(5v, spdt, rated coil current 80mA for each) with pic mcu.
It is noticed that at no load(when the relays not being operated) the zener(5.1v, 1.3watt) is geeing heat.
And if the relays are kept turned on the zener is ok.
Can you suggest what should i...
hI,
The structure I want to use is 64x16 matrix, ie TWO P10-panels side by side. For that the DRIVER and MAIN two file is attached.
It is working fine in SINGLE-Panel,
but when trying to SCROLL(Right-Left scroll) with 2-Panel, its moving separately(panel wise), not altogether with 2-panel as...
HI,
What is INTCONbits.T0IE?
its Time0 interrupt enable bit.
Code is attached here in .txt format
The code is extracting time from rtc module I2C displaying at segments and the segments is refresing at every 1msec using timer0 and the multiplex is uded.
So, I think debounce routine is not clock...
Hi,
In software side, it is multiplex, xc8 comp to disp HH:MM:SEC, mcu reading from rtc readng at 24hrs format and then in software it is converted to 12hrs farmat under main().
H/W, 7seg CC, RTC1307.
All are working correctly , now I want to add a feature that is, when the time reach at...
Sorry to responce in delay!
@andre_teprom
Will you show your schematic ?
The segment-pcb is here attached here. Pl note I am using multiplx technique here.
From the schematic,
As desire type is CA type and that is why COMMON track is Anode-Control-Track and others all respective...
