Alongside the MYJG CO2 Laser Power Supply line ,ZYE maintains a second family: the LL Series power supply. Developed for industrial equipment power supply and specialized power supply applications, the LL line is a compact series focused on the 40W–60W segment — the power range most common in small-format laser engraving and cutting equipment.
This guide covers the four LL models currently in production, what the series is positioned for, and how it fits alongside ZYE's two larger lines.
Full Model Range
The LL Series power supply family currently includes four production models. All are built at ZYE's Jinan, Shandong facility with a monthly production capacity of 20,000 units.
| Model | Rated Power | Max Output Voltage | Max Output Current | Input Voltage | Typical Price (USD) |
|---|---|---|---|---|---|
| L40W-L | 40W | 20 kV | 20 mA | AC 110V / 220V | 49–49–59 |
| L50W | 50W | 24 kV | 20 mA | AC 110V / 220V | 69–69–89 |
| L60W (standard) | 60W | 26 kV | 24 mA | AC 110V / 220V | 69–69–99 |
| L60W (engraver) | 60W | 26 kV | 24 mA | AC 110V | 69–69–99 |
Where the LL Series Fits
ZYE's three series answer different needs:
| Series | Power Range | Positioning |
|---|---|---|
| MYJG Series | 40W – 200W | The main workhorse line, widest wattage span, broad tube-brand compatibility |
| ZY Series | 60W – 180W | Premium line with RECI tube optimization and LCD display options |
| LL Series | 40W – 60W | Compact line for industrial equipment and specialized power applications |
The LL line's focus is narrow and deliberate: it serves the 40W, 50W, and 60W segment — the power band that dominates desktop and benchtop laser machines — with a compact form factor. The "L" model prefix and the series' positioning as an industrial equipment power supply distinguish it from the broader MYJG catalog, which spans the same wattages but extends much higher.
If you are unsure which series fits your machine, the reliable approach is to confirm your exact electrical and mechanical requirements before ordering — a point ZYE's own product page emphasizes.
Models in Detail
L40W-L — 40W Entry Model
The L40W-L is the smallest unit in the LL line, rated at 40W with a maximum output of 20 kV at 20 mA. Available in both AC 110V and AC 220V input variants, it drives 40W glass CO2 laser tubes for compact engraving and cutting equipment.
At 49–49–59, the L40W-L sits at the entry point of the series and serves as a specialized power supply for small-format machines where space is limited.
L50W — Compact 50W
The L50W delivers 24 kV at 20 mA for 50W CO2 laser systems, with the compact design the LL line is built around. Its dual-voltage input (110V/220V) keeps it compatible with machines across different regional mains standards. Priced at 69–69–89, it covers the 50W segment used by small workshops and benchtop engraving systems.
L60W — 60W, Two Variants
The L60W is available in two configurations:
- L60W standard — AC 110V / 220V input, 26 kV / 24 mA output, 69–69–99
- L60W engraver — AC 110V input, 26 kV / 24 mA output, 69–69–99
Both drive 60W glass CO2 laser tubes. The engraver variant is configured for CO2 laser engraving machines specifically, while the standard variant covers general 60W systems. The L60W CO2 Laser Power Supply's 26 kV maximum output provides solid headroom for starting 60W tubes, including aging tubes whose starting voltage has drifted upward.
Application Scenarios
The LL Series power supply family targets these applications:
| Application | Typical Model |
|---|---|
| Small-format laser engraving | L40W-L, L50W |
| Benchtop CO2 laser cutting | L50W, L60W |
| 60W glass tube engraving machines | L60W (engraver) |
| Industrial equipment with 40W–60W lasers | All models |
| Specialized power applications | All models |
The series is positioned for industrial equipment power supply use — meaning machines where the power supply is one component in a larger integrated system, rather than a standalone hobbyist upgrade. For buyers sourcing a specialized power supply for a specific machine design, the LL line's compact form factor and focused wattage range make it a natural fit.
What to Confirm Before Ordering
ZYE's product page for the LL line lists the information buyers should verify before placing an order. Because different LL models can differ in input voltage, output specification, connector type, and installation dimensions, the page warns against selecting a replacement power supply by appearance alone.
Confirm these six points with your existing unit or machine design:
- Required input voltage — AC 110V or AC 220V
- Required output voltage and current — match your laser tube's rated power
- Equipment type and application — engraving, cutting, or integrated industrial system
- Installation space and dimensions — the LL line is compact, but exact fit matters
- Connector and wiring requirements — terminal layout must match your machine
- A photo or spec sheet of the existing power supply — the fastest way for our team to confirm the correct model
