Thanks swall, what would be plating/galvanising recommendation? [ I am not from this background]

Hi, Normally we use aluminum cabinets for outdoor electronics enclosure. To reduce cost we propose use of CRCA steel. Please suggest if this is OK and what type of plating and painting are required to achieve 10yr+ life.Regards

Hi All, Interesting reading:Researchers at Purdue University have further developed a technology that could represent a pollution-free energy source. The technology produces hydrogen by adding water to an alloy of aluminum and gallium...

dcosta, nothing nuclear about it. Just to repeat tinfoil- "Seems ridiculous, but who knows?". I merely tried to say initially most discoveries are looked upon on with ridicule.

Hi, Einstein gave the equation e=mc2, that theoretically means that you can get huge energy out of small matter. As everyone here I am also skeptical, however did any one notice magic of falling Apple, or splashing water before Newton and Archmedes?

davidbeach: Our suppliers do not have such software.

Hi All, my query is not fully answered.The GENSET is meant to be standby duty, typical 8 hours a day. We normally program A/C to start late or early. Gensets we have specs like say for 15KVA GENSET- 15KVA continuous and 16.5KVA standby max.rating at 0.8 pf. This model has 19bhp @1500rpm engine...

Hi All, We often have to size Diesel genset for telecom sites. My questions are A) how much continuous(8-12 hours) KW load (0.9PF) & no A/C can be put on a 1 PHASE 10KVA DG set. B)If we have SMPS load of 7.5KW (0.9PF) and A/C load 2KW (0.6pf) what should be min. DG set capacity in KVA &KW? Regards

Zip all needed files together with path info. This will ensure a 'good move'. br/

Hi Roger, I decided to give a hard look at this. I repeated your data in 20000 +rows in one worksheet, it takes about 2 seconds to organise with code given below. Have I overlooked anything? I am using excel 2000 . Application.ScreenUpdating = False l = Range("A65536").End(xlUp).Row For k = 2...

gomirage, "I always try to prioritize but always find myself doing things not on my to-do list." Make a list of tasks on paper. Mark 'A' in red for highest priority immediate deadline tasks( max. 3). mark 'B' in yellow for high priority longer deadline (max. 3). Cross out everything else...

Shearstrength, For about 2500 parts I use a EXCEL sheet to store all master data with unique number ( item id ) for each part. For new costing or quote sheet I just need to enter item id in one cell and other cells which contain VLOOKUP formula get required details e.g. description, order...

I looked at the original post of ParabolicTet "good communication skills are much more valuable than technical knowledge" Communication skills are very important as one goes up the ladder, however good communicator is not necessarily technically weak. In fact if you are technically sound you...

Can you consideruse OFFSET(reference,rows, cols,height,width)function? GOOD LUCK.

Hi, Hope that you have resolved all issues, please share the info with us. REgards.

Yes a well drafted schematic diagram makes life easier for everyone designer himself, testing , servicing - all. Many large organisations follow standards or create their own for docuentation including schematic diagram.If it is one of them you are lucky. method to analyse schematic circuits -...

Thanks radarray, I am somewhat a learner in 'motors' area. "both output transistors from being turned on at the same time." is a common issue in our dc/dc converter and other bridge drive designs. I understand that when changing logic modes the driver should go through 'open' mode...

"Motor is 12 V. RPM (freeload) is 5800, current 0.05 A. With Load, Speed is 5000 rpm, current 0.2 A." This translates into 12/0.05 = 240 Ohms at freeload and 12/0.2 = 60 Ohms Interestingly BA6219B lists R(L)=60 Ohms in test conditions.

The o/p current max given in datasheet for BA6219B is for 500microsec pulse at 1% duty cycle.You will probably need high watt RES without chopped drive. I made a stepper motor ( Perm magnet ) drive long time back.It needed bulky current limiting resistors .The solution was to chop the drive at...

Hi yanco , You were able to solve '7812 Get Hot / Vin Voltage Drop' yourself:-). I suppose this is the same circuit. W=I*I*R gives me 0.7 A at 5W across 10 Ohms; at 2.5W it is 0.5A What's current through 10 Ohms , it should be less than 0.5 A. Since 50 Ohms is also 'very hot' there is...
