Spare Part Overview & Technical Description
High-Voltage Industrial CO2 Laser Power Supply (ZR 80W / 120W Peak Output)
The ZR Power Supply is an industrial high-frequency, high-voltage regulated power supply specifically engineered to drive 80W, 90W, and 100W sealed CO2 glass discharge laser tubes (including Reci, EFR, Yongli, and SPT brands). Operating on standard 220V AC single-phase mains, this high-performance unit converts utility power into a continuous 0 to 40 kV DC high-voltage excitation potential, delivering the ultra-fast ionization rise time required for deep acrylic cutting, high-speed wood engraving, and intricate leather perforating.
Engineered around zero-current half-bridge soft-switching resonance topology, the power supply achieves exceptional electrical efficiency exceeding 90%, significantly suppressing thermal waste heat and protecting internal potting transformers from thermal breakdown. The unit features built-in protection against open-circuit discharge, automatically halting high-voltage output if the cathode connection is severed or if the laser tube fractures. Dual analog (0–5V) and digital PWM control inputs provide universal plug-and-play compatibility with Ruida, Trocen, Leetro, and CorelLaser digital controllers.
Advanced High-Voltage, Protection & Circuit Highlights:
- Zero-Current Half-Bridge Soft Switching: High-efficiency resonance inverter topology reduces switching losses, dramatically extending transformer life and lowering enclosure operating temperatures.
- Ultra-Fast < 1 ms Pulse Response: Instantaneous ionization response time enables sharp vector corners and ultra-crisp raster photo reproduction at high scanning speeds without lag.
- Comprehensive Open-Circuit Protection: Automatically detects when the laser tube is disconnected or ruptured, cutting off high-voltage output immediately to prevent chassis flashover.
- Dual Power Modulation Support: Seamlessly accepts both continuous 0 to 5V analog voltage control and 5V PWM digital frequency modulation from all major laser controllers.
- Integrated Manual Test Pushbutton & Status LEDs: Built-in diagnostic test switch allows technicians to verify laser tube firing, beam alignment, and cooling interlocks without PC software.
- Closed-Loop Current Feedback Regulation: Compensates for AC line voltage fluctuations (180V to 250V), ensuring dead-stable laser tube current and consistent cut depths all shift long.
