1. Role in CO₂ Laser Machines

The laser power supply is one of the most critical components in a CO₂ laser system. A ZYP power supply:

• Provides stable high-voltage output to the laser tube

• Controls laser output power accurately

• Protects the laser tube from overcurrent and overload

• Enables PWM/analog control from the controller

• Ensures consistent cutting and engraving quality

Without a proper power supply, laser tube performance and lifespan are severely reduced.

2. Working Principle

1. AC input (220V or 110V) enters the power supply.

2. Internal circuits rectify and filter the AC into DC.

3. High-frequency switching boosts voltage to high DC levels.

4. Controlled current is delivered to the CO₂ laser tube.

5. Laser output power is regulated via control signals (PWM/TTL/Analog).

6. Safety circuits monitor load, temperature, and water protection.

3. Main Components

• High-voltage transformer

• Switching MOSFET / IGBT modules

• Rectifier and filtering circuits

• Control PCB

• Cooling fan

• High-voltage output terminals

• Signal input terminals (L, IN, G, WP, 5V)

4. ZYP Power Supply Models & Power Range

Always match the power supply rating with the laser tube power.

5. Electrical Specifications (Typical)

• Input Voltage: AC 220V ±10% (some models support 110V)

• Output Voltage: Up to 20–30 kV (depends on model)

• Max Output Current: 20–35 mA

• Control Signal: TTL / PWM / Analog (0–5V)

• Efficiency: ≥90%

• Cooling Method: Forced air cooling

• Operating Temperature: 0°C – 40°C

6. Control & Signal Interfaces

ZYP power supplies support multiple control signals:

• IN / TTL: Laser on/off signal from controller

• L (PWM): Laser power modulation

• 5V: Reference voltage output

• G (Ground): Signal ground

• WP (Water Protect): Interlock input (must be connected)

These interfaces allow precise laser power adjustment and safety control.

7. Protection & Safety Features

ZYP power supplies include built-in protections:

• Overcurrent protection

• Open-circuit protection

• Short-circuit protection

• Water protection (WP interlock)

• Thermal protection

• Arc and overload detection

These features protect both the laser tube and machine electronics.

8. Installation Guidelines

• Ensure proper grounding

• Connect WP terminal correctly (chiller/water flow switch)

• Use high-voltage silicone wire

• Keep high-voltage cable short and insulated

• Avoid moisture and dust exposure

• Provide adequate airflow around the power supply

9. Maintenance & Troubleshooting

Routine checks:

• Cooling fan operation

• Electrical connections

• Output stability

• Error indicators (if any)

Common issues:

• No laser output → check WP signal

• Weak cutting → incorrect current or aging tube

• Power supply shutdown → overheating or overload
