600W PFC LLC Amplifier Audio Switching Power Supply IR2092 8954 3255 5630 7498 Default DC ±70V
Features:
- Input: AC100-240V 50/60HZ
- Output: main voltage DC ±70V can be fine-tuned in a small range, the best state is near the highest output voltage
- Auxiliary voltage: ±12V 0.5A, ±15V 0.5A, independent 12V 0.5A
- PFC power factor: 0.993
- Conversion efficiency: 90-95% (the higher the output main voltage, the higher the efficiency)
- Size: about 189 x 106 x 43mm/7.4 x 4.2 x 1.7" (subject to the actual product)
- Weight: 0.64KG/1.4LB
- Ripple: about 0.3% of the peak value (the test ripple needs to use a coaxial cable, the shorter the outer ground wire, the smaller the impact, the test value with the oscilloscope probe will be too large, because the probe ground wire will affect the value deviation)
- Independent inductance, less heat, more stable, and the voltage can also be fine-tuned
- Suitable for driving all types of power amplifier boards. If a Class A power amplifier board is fully loaded for a long time, a fan needs to be added for heat dissipation
- The LLC control board and the PFC part each use a small board, the components are facing outside, which is convenient for testing voltage or waveform, and also convenient for maintenance and debugging. Pfc part of the bridge stack, switch tube, and rectifier diode share a gate-shaped radiator. It is convenient to add a 40 x 40mm/1.6 x 1.6" fan under continuous load. The DC~DC part adopts solid 10mm/0.4" thick aluminum heat sink, and the heat sink tube faces outwards for easy disassembly and assembly. An 85℃ temperature control switch is installed in the middle, and the chip output will be turned off when the temperature of the heat sink exceeds 85℃
Package Included:
- 1 x Switching Power Supply
Note:
- Since each different parameter will use different withstand voltage components, the actual product will be different from the picture, and the appearance and color of some raw materials in each batch will be different, but the parameters are the same and will not affect use. Please make sure that you don't mind before purchasing.
