Optional output voltage: Type D: +-45V & +-17V & 17V Type E: +-50V & +-19V & 19V Type F: +-55V & +-21V & 21V Type G: +-60V & +-14V & 14V Type H: +-65V & +-15V & 15V Type J: +-70V & +-16V & 16V Type K: +-75V & +-17V & 17V Type L: +-80V & +-18V & 18V Specifications: - Input voltage: AC200-240V - Optional Main Output Voltage: ±45V, ±50V, ±55V, ±60V, ±70, ±80V - Output Voltages: Main ±80V (Optional); Independent 12V; Auxiliary ±12V - Voltage Regulation Accuracy: Main No-load ±10%; With load ±3%; Independent No-load ±15% (for AC220V input) - Output Current: ±80V / 5.5A (Depends on the main output voltage you choose); Independent 12V/0.5A; Auxiliary ±12V/0.5A (with main voltage supply to ground) - Continuous Power: 600W (can work continuously at 25℃) - Rated Power: 1000W (can work continuously for about 5 minutes at 25℃ ambient temperature. Cooling fan should be added for long time operation) - Instantaneous Power: 1500W (power generated during dynamic signal impact, time is less than 100ms) - Conversion Efficiency: Max. 95% - Weight: 430g - Since the switching power supply only regulates the main voltage, the current of independent and auxiliary outputs must be less than the current of main voltage output. For example, when the current of main voltage is 10mA, the auxiliary and independent cannot withstand a load of more than 10mA. Packing List: 1* Switching Power Supply NOTE: 1. This product is a bare board with high voltage circuit hazards and must be purchased by someone who can use it. Our store will not bear any consequences caused by use! 2. For commercial purposes, some circuits and components are polished and encrypted, and schematic diagrams, PCBs, and technical support are not provided 3. For long-term high-power use, please add a fan for air cooling. The power supply is equipped with overheating, overcurrent, and short circuit protection. The overcurrent and short circuit protection is locked protection, and the main filter capacitor voltage must be disconnected from the AC power supply and reduced to 0V before starting again. This power supply is a true LLC power supply, with a high-frequency sine wave resonant circuit. It is not an ordinary square wave switching power supply, and is very suitable for use in power amplifiers with good results 4. Each power supply is tested before shipment, and our store is not responsible for any burnt transformers, pipes, or ICs. If maintenance is required, we will bear all costs ourselves! The board is constantly upgraded and revised, and the component circuit may be modified.
