Hunter education is available as either TRADITIONAL or ON-LINE courses in the states of Washington and Oregon. Oregon also offers a workbook option.
Instructor-led courses are considered the best option for students under 14 years of age and/or for individuals having minimal hunting experience.
These 13 to 18 hour courses provide students with the highest level of interactive, hands-on training from experienced, certified, volunteer instructors.
Course curriculum includes firearm safety and handling, hunter ethics, wildlife management and conservation, survival and regulations.
Students must also attend a field exercise which includes a final examination, live-fire and safe firearm handling.
Students will be evaluated on their class participation, exam score, field exercise participation and safety during the live-fire exercise.
On-line courses and Field Skills Evaluations are provided by the Department of Fish and Wildlife in the states of Oregon and Washington through HunterCourse.com. All questions and inquiries concerning that should be directed to those agencies.
Scheduled hunter courses may be posted on the club's event calendar. Please check the links for the latest available course scheduling.
This is a two prong approach to a situation I'm looking at for the place I work. Like many industrial/commercial OEM's you have to cater to the single phase end of things as well as 3-phase. I want to get away from single phase motors and stick to 3-phase. No start windings, no capacitors, no extra mechanical bits. In terms of reliability, if I can remove all single phase motors from my shelf (but still cater to the 230V crowd), I will be a happy man.
My question is, is there a "barebones" VFD/Driver on the market that essentially only packs a handful of features:
Handle from 1/2 HP to 5 HP capacities (should just be a heatsink and internal component sizing at that point?)
I've been looking for sometime reputable with a ultra-simplified feature list but had no avail. At this point, I'm ready to build one from scratch if that's what needs to be done. I figured if anyone will know it will be you folks here...I've looked through ACTech, ABB, Siemens, Mitsubishi, etc...but no luck. If there isn't anything terribly cost effective on the market, what are we looking at if I wanted to hire someone smarter than myself to help tackle getting one put together?
Are you looking for something basic just to try to keep costs down? I don't think you can do much better bang-for-buck wise than the GS1/GS2 drives sold by Automation Direct, which are simplified siblings of the GS3 Durapulse drives. (I'm sure you can get drives that cost less to buy, but the support and supply chain behind the the drive has to be factored in as well. This is also an important consideration when thinking about rolling your own.) Even the GS1s have more features than you asked for, but you can certainly set them up with basic start/stop controls, ramp up/down, etc. The only part I think you're going to have trouble with is single phase input at >2HP.
VFDs cost money, it’s as simple as that. Don’t try building your own unless you need many thousand per year. It will take ages and you won’t get good economies or scale. Also, if you pursue the cheapest possible drive you’re probably making some sacrifices on reliability/lifespan.
You may be able to find motors with integrated drives. These are quite easy to deploy and may be a useful option.
On the EMC front, you also need to consider a) fitting EMC filters onto the drives ($) or b) getting drives with filters built in ($) or c) using screened cabling from the drive to the motor ($). It’s $ all round, I’m afraid.
One possibility for getting people to try VFDs is to talk up the soft start, soft stop and variable speed features. These features can really help with the mechanical side of a process (e.g. don’t need dampers, cut down pressure spikes in pipelines).
Please note that almost all VFDs have big DC capacitors inside which will suck down big inrush currents, and most VFDs will generate harmonic currents (especially with single phase supply).
A 400W driver will be very different from a 4kW driver, they should be different products, is not only matter of bigger heatsink, the cost and performance differences are too big to have just one model
All drivers have some kind of overload protection. Or in case of FOC inverters they don't overload, they just regulate the speed/power to the maximum possible without overload
Depending on where you live you will be required to have power factor correction on single phase for more than 200W. Even if isn't required, it is very recommendable
EMC is a world on itself. It isn't as easy as buying a filter (if you want to do it properly) and it depends if you have to comply with an specific EMC standard
It is VERY different if you just need 10~100 VFDs in total or if you need >1000 per month. If it's the first, just buy something already done, unless you want to learn and you are ready to spend more resources than what those drivers would cost.
Thanks for all the insight on these...appreciated. It's certainly on the scale of 500+ a year but even then, yes they are going to be a cost. I definitely understand that...after watching a few tear downs I certainly have a new respect for what goes into one as far as controls/brains go. I didn't even think to look into Automation Direct for them, so I will give a couple a try on a trial basis.
@Jbb Agreed, they are costly and for good reason. Certainly you have to know when to draw the line on "too cheap" just buys you headaches in the future which nobody likes.
Ever wonder how you would get your companion back if they ran away and got lost? We can provide microchip implantation services so that you will be contacted if your companion enters an animal control facility or veterinary clinic when they are lost. The information contained in the microchip can be linked back to you and can help to reunite you and your companion.
FABRE TP aims to support stakeholder involvement in the set up of a partnership led by industry to tackle major issues concerning sustainable animal breeding and reproduction in Europe, and taking into account what is happening in the developing world.
The Animal Task Force is a European Public-Private Platform which promotes a sustainable and competitive livestock sector in Europe. It is a leading body of expertise, representing key stakeholders from industry, farmers and research from across Europe.
The European research project FISHBOOST will advance European aquaculture to the next level by developing balanced and sustainable breeding programmes to improve breeding programmes for the six main fin fish species. For more information visit the FISHBOOST website.
