600W LLC Power Amplifier Switching Power Supply Board Single Double Output Positive and Negative +65V Diy Audio Amp

Product description:

For long-term high-power use, please add fan cooling. The power supply has overheating, overcurrent and short circuit protection. Overcurrent and short circuit protection are lock-up protection. The voltage of the main filter capacitor such as the AC power supply must be disconnected to 0V to restart. This power supply is a real LLC power supply, the resonant circuit is a high-frequency positive sine wave, not an ordinary square wave switching power supply, it is very suitable for power amplifier use, and the effect is good

Single voltage cannot be used as dual voltage, and dual voltage cannot be used as single voltage

Parameter:

Input voltage: AC200-240V

Output: single voltage 50V/12A; dual voltage ±50V/6A; independent 12V/0.5A (unregulated, it will become lower as the main voltage becomes lower, used in occasions with low requirements, such as powering fans, etc.)

Special reminder: 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 can not carry loads above 10MA;

Voltage regulation accuracy: main no-load ±3%, with load ±3%; (when AC220V input)

Rated continuous power: 300W (25℃ ambient temperature with fan)

Instantaneous power: 600W (it can work for 30 seconds when the ambient temperature is 25°C and the fan is added)

Conversion efficiency: Max 98%

Dimensions: length, width and height = 116*67*40mm
