LLC power amplifier switching power supply finished board 600W dual output positive and negative

Description

The main output voltage has: ±30V, ±35V, ±40V, ±45V, ±50V, ±55V, ±60V, ±65V, ±70, ±75V, ±80V and many other options, independent 12V/0.5A (unregulated, with the main The voltage becomes lower and lower, and it is used in the occasions where the requirements are not high, such as powering the fan, etc.). Different voltage capacitors, component parameters are different, and the actual product shall prevail.

The parameters are as follows:

Input voltage: AC200~240V Output: Dual voltage ±50V/6A, independent 12V/0.5A (unregulated, lower as the main voltage becomes lower, used in less demanding occasions, 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 cannot carry loads above 10MA. Voltage stabilization accuracy: main no-load ±3%, loaded ±3% (when AC220V input) Continuous power: 300W (continuous work at 25℃ 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: length, width and height=116*67*40mm Weight: 265g

Purchase note:

1. This product is a bare board that has high voltage circuits and must be purchased by someone who can use it! The company researches and develops by itself, the quantity can be customized according to customer requirements, but the quantity is small. 2. For commercial purposes, some circuits and components are polished and encrypted. Schematics, PCBs and technical support are not provided. Those who want to study and research, please detour, and don’t buy if you mind! 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 is lock-up protection. The AC power supply must be disconnected and the main filter capacitor voltage drops to 0V to restart. This power supply is a real LLC power supply, and the resonance circuit is a high-frequency sine wave. It 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, and the board is continuously upgraded and revised. If the component circuit may be changed, please refer to the actual shipment.
