When you're spec'ing an industrial control transformer, the first question usually isn't brand-it's line voltage. The Eaton C5000K2A and the HPS PH250MQMJ are two control transformers that approach that question very differently, and their price tags reflect the difference.
Both units are built for industrial control panels, but they serve different scenarios. The Eaton offers a broader input window and a standard control-voltage secondary. The HPS is a simpler, lower-priced unit for a single primary voltage. Knowing your line voltage is the first step; the second is deciding whether you need that flexibility.
Quick Verdict
If your control panel runs on a dedicated industrial feed and you want to watch costs, the HPS PH250MQMJ gives you a functional control transformer at a much lower price. If you need a transformer that can handle different incoming line voltages and deliver a standard control voltage, the Eaton C5000K2A offers that flexibility, but at a higher price.
At a Glance
| Product | Price | Voltage Configuration |
|---|---|---|
| Eaton C5000K2A | $450.00 | 220-240V or 440-480V primary; 110-120V secondary; 50/60Hz |
| HPS PH250MQMJ | $149.99 | 480V primary |
The table highlights the core difference: the Eaton stretches across two primary voltage ranges, while the HPS stays in a single range.
Where Each Wins
Choosing between them comes down to whether your plant has one standard feed or several.
Eaton C5000K2A wins on flexibility
- Accepts two different primary voltage ranges, covering both common industrial feeds.
- Provides a standard control-circuit secondary output.
- Operates on both 50Hz and 60Hz systems.
HPS PH250MQMJ wins on price
- Sits at the lower end of the price range, making it a lighter cost for a basic installation.
- Simple single-primary design keeps the spec straightforward.
Product Notes
Eaton C5000K2A
The Eaton C5000K2A is the more expensive of the two at $450, but it makes up for that with a wider input range. It accepts both 220-240V and 440-480V primary feeds, steps down to a 110-120V secondary, and runs on 50/60Hz. That makes it a useful option for facilities that may need to switch incoming line voltages or that operate on a 50Hz network. If your machine control cabinet needs a transformer that can adapt to different power sources, this is one to consider. The tradeoff is the price: it's a substantially larger investment than the HPS. And if your application is a fixed single-voltage line, you're paying for flexibility you may never use. On the plus side, the unit is sold as new, which can be a factor if you prefer factory-fresh components for critical controls. That said, the dual-voltage capability also means you can stock one unit for two different line types, simplifying your spares inventory.
HPS PH250MQMJ
For a fixed 480V primary, the HPS PH250MQMJ is the lower-priced option at $149.99. It is a 250VA unit with a 2.08A primary rating, and it's designed for a 480V input. If your line voltage is already 480V and you don't need the dual-voltage flexibility of the Eaton, this unit gives you the essentials without the extra cost. The limitation is that its primary is specified for 480V only, so a lower-voltage supply would need a different transformer. The seller is not an authorized distributor, and the original manufacturer warranty and support do not apply, so factor that into your buying decision. For many industrial control cabinets, that's an acceptable trade-off when the price difference is as wide as it is here. If you have a dedicated 480V feed and a clear spec, the HPS gets you running without overcomplicating the purchase.
Final Choice by Use Case
Choose the Eaton C5000K2A if your installation needs to accommodate different incoming line voltages and you want the flexibility to switch standard control voltages. Choose the HPS PH250MQMJ if you have a consistent 480V feed and want the lower-cost unit for that fixed setup. Both are legitimate industrial control transformers; the best fit depends on your specific supply.
