LLC-1500W Amplifier Power Supply Board LLC Soft Switching Power Supply Optional Main Output Voltage
Description:
This power supply is a real LLC resonant power supply. The resonant 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.
Attention:
- It is a bare board with high-voltage circuit, which requires users to have professional knowledge.
- For commercial purposes, circuits and components are polished and epoxy resin potted. Schematic diagrams, PCB and technical support are not provided.
- For long-term high-power use, please add fans for air cooling. The power supply is protected against overheating, overcurrent and short-circuit. Over-current protection and short-circuit protection are lock-up protections. The AC power supply must be disconnected and the main filter capacitor voltage drops to 0V before it can be restarted.
- Each power supply is tested before delivery. The board is constantly upgraded and revised, and the component circuit may be changed, please refer to the actual delivered one.
Product Parameters:
- Input voltage: AC200-240V
- Optional Main Output Voltage: ±45V, ±50V, ±55V, ±60V, ±65V, ±70V, ±75V, ±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 / 6.3A (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℃ ambient temperature. Long-term 600W use needs extra fan cooling)
- Rated Power: 1000W (can work continuously for about 5 minutes at 25℃ ambient temperature)
- Instantaneous Power: 1500W (power generated during dynamic signal impact, time is less than 100ms)
- Conversion Efficiency: Max. 95%
- Size: 143 x 96 x 38mm (LxWxH)
- Weight: 430g
Package Included:
- 1 x Switching Power Supply
Note:
- Different voltages, different batches of capacitors, component parameters will vary, please refer to the actual product.
- 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 that time is 10mA, and the auxiliary and independent cannot carry loads above 10MA.
