The treatment efficacy, safety performance, and overall service life of tattoo removal machines and aesthetic medical instruments depend critically on the comprehensive performance of the built-in laser power supply. However, four major issues — uneven energy output, frequent alarms, non-compliance with safety standards, and recurring malfunctions — have long plagued numerous equipment manufacturers. Today, we take an in-depth look at LZY's self-developed ND:YAG passive laser power supply system, presenting a reliable technical solution and customized services for medical-grade power supplies.

QPM500 Actual Photo Power Supply Panel Interface

LZY's ND:YAG passive laser power supply is available in two models: QPM500 and QPM2000, compatible with all single-lamp and single-lamp dual-rod handpieces on the market. Taking the [QPM500]{.underline} as an example, all power supplies in the series come standard with a pre-ionization module.

I. Integrated Modular Architecture — Eliminating Messy Split-Type Wiring

Unlike conventional split-type power supplies on the market (with separate power supply, control board, capacitors, relays, etc.), the QPM500 adopts a 4-in-1 modular design that integrates: high-power charging power supply + pre-ionization module + high-voltage output control + built-in large capacitors + complete system diagnostics + serial-port touchscreen.

Features a proprietary 50A high-current plug-in connector, enabling quick assembly/disassembly without complex wiring — significantly improving installation efficiency, reducing after-sales maintenance, and saving labor costs.

The unit integrates multiple functional anti-reverse-plug control terminals, compatible with external peripherals such as water flow sensors, temperature sensors, foot switches, and aiming beam controls. It also includes a P1 main control port with full 20-pin coverage, eliminating the need for an additional external control board — reducing assembly workload and improving efficiency.

Forced-air cooling structure with ventilation openings across the entire chassis. Operating temperature range: -15°C to +45°C, ensuring stable operation in high-temperature workshops as well as cold-chain storage environments.

II. Triple-Wavelength Precision Matching — Covering All Categories of Aesthetic Medical Procedures

Comes with a 4.3/8/10.4-inch LCD touchscreen, booting directly to the wavelength selection interface. Supports three major aesthetic wavelengths: 532/755/1064nm, with customizable interface styles available upon request.

Boot Animation Wavelength Selection Interface

532nm Green Light: For removal of special-color tattoos;

755nm Alexandrite Laser: For treatment of pigmented lesions and superficial age spots;

1064nm Infrared Light: For deep melanin removal and black tattoo elimination, suitable for different skin tones.

The QPM500 delivers a maximum single-pulse energy of 50J with a frequency range of 1–10Hz. The QPM2000 delivers 200J single-pulse energy with a frequency of 1–5Hz. Patented pulse energy consistency algorithm ensures minimal energy fluctuation per pulse, preventing localized overheating and burns — significantly improving patient satisfaction.

III. Comprehensive Safety Protection — Compliant with Safety Standards

✔ Four Intelligent Alarm Systems: Water flow / Overtemperature / Pre-ionization / Charging abnormality — real-time pop-up alerts. Automatic shutdown above 50°C; restart only permitted after cooling to below 45°C;

✔ Handpiece Connection Detection: High-voltage output is locked when no treatment handpiece is connected, eliminating the risk of no-load high-voltage electric shock;

✔ Threefold Hardware Protection: Overload / Overvoltage / Overcurrent protection. Leakage current < 0.4mA. Three-pin grounding terminals enforce electric shock prevention.

IV. Cost-Saving Advantages for Equipment Manufacturers

✔ Comes with complete touchscreen driver pre-installed, supporting 4.3/8/10.4-inch screen options — no additional HMI development required;

✔ QPM500 lightweight design at only 3.1kg, dimensions 269×124×124mm — reducing equipment chassis size and lowering enclosure mold costs;

✔ 12-month full-unit warranty, with precise fault localization and simplified maintenance procedures — significantly reducing after-sales costs for equipment manufacturers;

✔ Supports software serial-port upgrades — future feature iterations can be updated remotely without disassembling the unit.

V. Application Areas: Tattoo Removal, Eyebrow Removal, Melanin Elimination
