How to Distinguish MYJG80W and MYJG100w CO2 Laser Power Supply
Published 2025-04-30 by the Weihua Laser engineering desk.
Why Power Supply Labels Are Not Enough
Replacing a failed CO2 laser power supply or upgrading machine performance requires matching the correct wattage. The ZYE MYJG series covers 40W to 300W, but market competition has led to misleading labeling. Some sellers attach 100W stickers to 80W units to attract buyers with lower prices. Relying solely on the external label creates risk for procurement engineers who need consistent machine output.
Physical Dimensions And Circuit Count
To distinguish a MYJG80W from a MYJG-100W, check the physical size first. The diagrams show that the 100W unit has different dimensions than the 80W model. Next, inspect the internal circuits. Both models contain two high-voltage packs, but the 80W unit has one set of circuits, while the 100W unit has two sets. This internal difference is the primary indicator of true power capacity.
Stability Under Heavy Load
The MYJG-100W is more stable under heavy loads due to its two sets of internal circuits. An 80W supply may overheat or fail to maintain consistent output when pushed beyond its design limits, even if labeled as 100W. For workshops running continuous engraving or cutting jobs, this stability difference directly impacts downtime and material waste. Always verify the circuit count before accepting a replacement unit.
Display Options And Price Variance
Price differences between same-wattage units often stem from configuration options. The standard configuration does not include a digital or LCD display. If your operation requires real-time voltage monitoring, specify the display option when ordering. These features affect the final cost, so ensure the quote matches the exact configuration needed for your machine's control interface.

Buyer Questions
Questions On This Topic
How can I tell if a ZYE power supply is 80W or 100W?
Check the physical dimensions and the internal circuit count. The 100W model has two sets of circuits, while the 80W model has one. Do not rely on the external label alone.
What are the dimensions of the MYJG80W and MYJG-100W?
The dimensions differ between the two models. Please refer to the specific technical diagrams provided in the product documentation or request them from our sales team for accurate comparison.
Does the MYJG-100W perform better than the 80W under load?
Yes, the MYJG-100W is more stable under heavy loads because it contains two sets of internal circuits compared to the single set in the 80W model.
Are digital or LCD displays standard on ZYE power supplies?
No, the standard configuration does not include a digital or LCD display. These are optional features that affect the price, so specify them if you need real-time monitoring.
What wattage range do ZYE power supplies cover?
ZYE laser power supplies range from MYJG-40W and 60W up to MYJG-300W, covering most standard CO2 laser engraving and cutting machines.
Can I replace an old power supply with a higher wattage unit?
Yes, but ensure the new unit matches your machine's voltage and control requirements. Check the physical dimensions and circuit configuration to confirm compatibility before installation.
