700W Main Output Voltage 30V/35V/40V/45V/50V/55V/60V/65V/70V/75V/80V LLC Switching Power Supply Board For Power Amplifiers

700W Main Output Voltage 30V/35V/40V/45V/50V/55V/60V/65V/70V/75V/80V LLC Switching Power Supply Board For Power Amplifiers

Product Introduction:
Optional main output voltages are ±25V, ±30V, ±35V, ±40V, ±45V, ±50V, ±55V, ±60V, ±70, ±80V. ±55V is delivered by default. Different voltage capacitors, component parameters are different, the actual product shall prevail. If you need other voltages, please tell us the voltage you want when purchasing.

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.

Product Parameters:
- Input voltage: AC200-240V
- Output: main voltage ±55V/6.5A; independent 12V/0.5A; auxiliary ±12V/0.5A (share ground with the main voltage) (auxiliary and independent unregulated, the main voltage becomes lower and lower, used in low requirements occasions, such as powering a fan, etc.)
- Attention: Since the switching power supply only stabilizes the main voltage, the current of the independent and auxiliary output must be less than the current of the 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: 350W (continuous work at 25°C ambient temperature)
- Rated power: 700W (continuous work for about 5 minutes at 25°C ambient temperature, long-term work plus fan cooling)
- Instantaneous power: 900W (power generated during dynamic signal impact, time is less than 100 milliseconds)
- Conversion efficiency: Max. 98%
- Dimensions: 96*96*38mm/3.8 x 3.8 x 1.5" (LxWxH)
- Product weight: 310g

Package Included:
- 1 x Switching Power Supply Board

Note: The product have 30V/35V/40V/45V/50V/55V/60V/65V/70V/75V/80V for optional, please tell us the voltage you prefer.
