The order that started it all
When I took over purchasing for our mid-sized manufacturing facility back in 2020, I was told one thing pretty clearly: "Keep costs down." So I did what any new admin buyer would do. I chased the lowest quotes.
Here's the thing—our facility handles about 60-80 orders annually across 8 different vendors for things like terminal blocks, relays, and power supplies. My job was to keep the engineers happy and the finance department off my back. I thought those two goals were in conflict. Turns out, I was wrong.
My initial mistake with power supplies
In early 2022, we needed a batch of DIN rail power supplies for a machine upgrade. I found a quote that was about 30% cheaper than our usual supplier. Looked fine on paper—specs were similar. I placed the order for 15 units. Saved us roughly $800.
That $800 savings cost us $3,200 in the end.
Within three months, two units failed. The replacements took five weeks to arrive because the vendor didn't have local stock. Production line downtime alone was estimated at $1,800. Then they couldn't provide proper invoicing—handwritten receipts only. Finance rejected the expense report. I ate $400 out of our department budget just to cover the expedited shipping for the replacements.
Did I feel stupid? Absolutely. But more than that, I felt bad for the maintenance team. They had to rewire those cabinets twice. They didn't sign up for that.
Why I finally switched to Weidmuller
After that disaster, I sat down with our senior electrician, Jackie. He'd been recommending Weidmuller power supplies for years. I'd always said they were "too expensive." But after calculating total cost of ownership—including downtime, replacement labor, and shipping—the Weidmuller quote was actually cheaper.
"Look," Jackie said. "You buy cheap, you buy twice. Weidmuller stuff just works. And if something does go wrong, their support is actually helpful."

I'm not saying budget options are always bad. I'm saying they're riskier. And risk in manufacturing? That's real money.
So in Q4 2022, I placed our first official order for Weidmuller PROeco power supplies. 20 units. The total was about 15% higher than the 'budget' option. But this time, I knew what I was paying for: real technical documentation, proper invoicing, local stock through their distributor network, and a warranty that didn't require me to make three follow-up calls.
I also bought a Weidmuller 2660 flip crimper for the maintenance team around that time. At first, I thought $180 for a crimper was steep. Then I saw it. Solid, ergonomic, easy to use—no guessing whether the terminal was crimped properly. Jackie showed me how to use it in about two minutes. "You just press and it clicks," he said. "No hand cramps." Since then, we've had zero failed crimps on terminal blocks. Zero. Compare that to the cheap crimper we had before, which caused intermittent connections that took hours to troubleshoot.
Convenience is a feature, not a luxury
Here's what I learned the hard way: for admin buyers like me, convenience is a feature. Not a luxury—a real, measurable feature.
- Time savings: With Weidmuller's distributor, I can place an order online, get a proper quote, and have it shipped within 48 hours. No chasing people for paperwork.
- Fewer returns: The WDU 4 Weidmuller terminal blocks we use now? They fit perfectly every time. No more "wrong size" surprises.
- Internal satisfaction: The engineers stopped complaining about power supply failures. That alone is worth something.
I have mixed feelings about vendor loyalty. On one hand, I want competition to keep prices fair. On the other, consistency saves me hours of administrative headache. These days, I use a primary + backup system: Weidmuller is our primary for power supplies, terminal blocks, and tools. We have one backup vendor for niche items, but honestly, I rarely need them.
Dodged a bullet on rush charges
Last month, we had an urgent project come through. Needed a special relay module in three days. Normally, that means rush fees. But our Weidmuller distributor had it in stock, and regular shipping got it here in two days. No expedite charge. Dodged a bullet there.
So glad I switched when I did. If I'd stuck to the lowest-price strategy, I'd still be dealing with failures, paperwork, and late-night phone calls from maintenance.
What I'd tell other admin buyers
If you're managing industrial component purchases, here's my advice:
- Don't look at the unit price. Look at the total cost: shipping, downtime, reorder risk, and your own time.
- Find a vendor whose invoicing doesn't give you headaches. Seriously. Finance will thank you.
- Trust your internal experts. If your electrician or engineer recommends Weidmuller, listen to them. They're the ones who have to work with this stuff.
- Test one product before committing to a full line. Buy one Weidmuller power supply, try it out. You'll see the difference.
Prices as of January 2025. Verify current rates with your local distributor. But honestly, the price difference is small compared to what you save in headaches.
So yeah. I started as the admin buyer who chased the lowest quote. Now I'm the one who says, "Buy Weidmuller, save the headache." Funny how experience changes things.
