Hamgeek 600W Switching Power Supply Board 600W Single And Dual Output Efficient High Sound Quality For Audio Power Amplifier Version Introduction: There are two output voltages, single and dual, and the default is dual output ±55V. If you need other voltages, please choose the type you want when purchasing. There are optional main output voltages, including 24V, 32V, 48V, 60V, 70V, 80V, ±25V, ±30V, ±35V,±40V, ±45V, ±50V, ±55V, ±60V, ±70, ±80V. Due to the use of different voltage capacitors, component parameters are different, and the actual product shall prevail. Read Before Purchasing: 1. This product is a bare board that has high voltage circuits and must be purchased by someone who can use it. Our store does not bear all consequences caused by use! 2. For commercial purposes, some circuits and components are polished and encrypted, and schematic diagrams, PCB and technical support are not provided! Please make sure that you don't mind before purchasing. 3. For long-term high-power use, please add fan air cooling. The power supply has overheating, overcurrent and short circuit protection. Over-current and short-circuit protection are lock-up protections. AC power supply must be disconnected, and the main filter capacitor voltage will drop to 0V before powering on again. This power supply is a real LLC power supply, and the resonance circuit is a high-frequency sine wave, which is not an ordinary square wave switching power supply. It is very suitable for power amplifiers and has good effects. 4. Each power supply is tested before shipment. The board is continuously upgraded and revised. The component circuit may be changed, please refer to the actual delivered ones. Parameters: - Input voltage: AC200-240V - Output: Single voltage 55V/10.91A; Dual voltage ±55V/5.45A; independent 12V/0.5A (unregulated, lower as the main voltage becomes lower, used in less demanding occasions, such as powering fans, etc.) - Attention: Since the switching power supply only stabilizes the main voltage, the current of independent and auxiliary output must be less than the current of main voltage output; for example, the current of the main voltage at the time is 10mA, and the auxiliary and independent cannot carry loads above 10MA; - Voltage stabilization accuracy: main no-load ±3%, loaded ±3%; (when AC220V input) - Continuous power: 300W (continuous work at 25°C ambient temperature) - Rated power: 600W (continuous work for about 5 minutes at 25°C ambient temperature, long-term work plus fan cooling) - Instant power: 800W (power generated during dynamic signal impact, time is less than 100 milliseconds) - Conversion efficiency: Max. 98% - Dimensions: 116*67*40mm/4.6 x 2.6 x 1.6" (LxWxH) - N.W.: 265g Package Included: - 1 x Switching Power Supply Board
