There are two output voltage options, single and dual, please choose according to your needs!
Different voltages and different batches of capacitors may result in slight variations in component parameters. Please refer to the actual product.
Purchase Notes:
1. This product is a bare board with high-voltage circuits and is dangerous. It must be purchased by individuals who are capable of using it. Our store is not responsible for any consequences resulting from its use! Developed in-house by the company, customizations are available for bulk orders based on customer requirements. No negotiations for small quantities.
2. For commercial purposes, some circuits and components have been sanded and encrypted. No schematics, PCBs, or technical support will be provided. Please look elsewhere if you intend to use this for learning or research purposes. Do not purchase if this is a concern!
3. For long-term high-power usage, please add a fan for cooling. The power supply includes overheat, overcurrent, and short-circuit protection. The overcurrent and short-circuit protections are latch-type protections; the AC power must be disconnected, and the main filter capacitor voltage must drop to 0V before re-powering to restart. This power supply is a true LLC power supply, with a resonant circuit that produces a high-frequency sine wave, not the common square wave switching power supply, making it very suitable for amplifier use with excellent results.
4. Each power supply is tested before shipment. Our store is not responsible for any burnt transformers, tubes, or ICs. If repairs are needed, all costs will be borne by the buyer! The board is continuously upgraded and revised, and components and circuits may be altered. Please refer to the actual shipped product.
Parameters are as follows:
Input voltage: AC200-240V
Output: Single voltage 50V/12A; Dual voltage ±50V/6A; Independent 19V/0.5A (not regulated, decreases as the main voltage decreases, suitable for low-demand applications such as powering fans, etc. The independent voltage varies with the main voltage and is indicated in the purchase title)
Special reminder: Since the switching power supply only regulates the main voltage, the current of the independent and auxiliary outputs must be less than that of the main voltage output; for example, if the main voltage current is 10mA, the auxiliary and independent outputs cannot handle loads above 10mA.
Regulation accuracy: Main no-load ±3%, loaded ±3% (when input is AC220V)
Rated continuous power: 300W (at 25℃ ambient temperature with a fan)
Instantaneous power: 600W (at 25℃ ambient temperature with a fan, operable for 30 seconds)
Conversion efficiency: Max 98%
Dimensions: Length x Width x Height = 116*67*40mm
Weight: 265g
