YZX-LLC-420W LLC Quasi-Resonant Soft Switching Power Supply Amp Power Supply Main Power Output ±85V
Read Before Purchasing:
- Please read this product description carefully before buying, please make sure you have a certain electronic technology knowledge.
- Because there is high voltage mains power on the input part of the power supply module, please pay attention to the safety of operation!
- When the output voltage is higher than 36V safety voltage, please pay attention to your own safety protection. Our store does not bear the consequences and losses caused by users' blind operation!
- The switching power supply is only used for power amplifiers. Its heat dissipation design is for power amplifiers. It is forbidden to use it for other non-amplifier occasions. If the damage is caused by blind use in other occasions, the consequences shall be borne by users! If it is used for special occasions, it must be used in a derating and you can consult customer service for details!
Specifications:
- Power: 420W
- Input power supply: AC200-240V 50/60Hz
- Ripple: about 0.3% peak (Coaxial cable is used for testing ripple, and the shorter the outer ground wire, the smaller the impact. When testing with an oscilloscope probe, the measured value will be too large, because the long probe ground wire will affect the value deviation)
- Main power output: ±85V
- Size: 120.7 x 81 x 36mm/4.8 x 3.2 x 1.4"
- Net weight: about 270g/0.6lb
Attention:
- In no-load conditions, it is normal for the output voltage to jump a little because its no-load chip is operating in intermittent power-on mode.
- In addition, the positive and negative voltages will have a certain error when there is no load, which is normal.
- The output voltage is a symmetrical voltage, such as the parameters of ±36V output, the positive and negative voltage parts must have the same load, must be symmetrical, and the load cannot be used only on one side. For example, if it only carries a load between the positive 36V and 0V, this will cause the transistors to work on one side, which will lead to abnormal protection, and even cause the board to heat and burn out. If it must be used with a single voltage, it can only be used between positive 36V and negative 36V, and the dropout voltage will be 72V. When a single voltage of 72V is used, the middle 0 point can be dispensed with, so that it does not affect the use! The same to other output voltage parameters!
- Product pictures are for reference only and please refer to the actual product! Different output voltages may use components such as capacitors of different colors, different withstand voltages or different volumes, and switching transformer tape of different colors. Once you buy this item, it means that you accept this clause!
- Each product has a warranty label on screw seals, these labels must not be damaged. The item cannot be returned if there is any unauthorized modification (such as drilling, making thread, grooving, etc. to destroy the appearance of the product) or warranty label damage.
Package Included:
- 1 x Switching Power Supply
