MOSFET Power Amplifier 200W

This 200W MOSFET Power amplifier is suitable for many applications such as Guitar Ampplifier, Mic or Home theater. As many people prefer because of its legendary robustness of MOSFET transistors. MOSFET amplifier is rated at 200W power with 4Ω speakers. It has good frequency range of 1 dB 20Hz up to 80kHz. THD is less than 0.1% at full power and signal to noise ratio when compared to 200W is better than -100 dB unweighted. Performance of the prototype Output power (RMS ):… 140W into 8 ohms, 200W into 4 ohms Frequency Response:. 20Hz – 80kHz-1dB points (see Figure 1) Input sensitivity: ………… 830mV for 200W into 4 ohms Distortion: … <0.1% (20 Hz – 20 kHz) (see Fig.2) Signal-to-Noise Ratio:. > 102dB unweighted, 105dB A-weighted with respect to 200W into 4 ohms Stability: Unconditional Originally, the “Pro Series One” was developed by Hitachi MOSFET A-3 metal containers. They are no longer available, and their counterparts from plastics are very difficult to obtain. Altronics on this situation and have essentially the same circuits designed for Plastic MOSFET corresponds Exicon by the United Kingdom. This required a re-design of the computer, so that all MOSFET and the pilot for all transistors on a plate are vertically mounted on the radiator. Besides the use of plastic in the power transistors, which greatly simplifies the assembly of the metal in comparison with A-3 power transistors, have Altronics spring clips in the proximity of the pairs of transistors, so things were still simple. The spring clips, just what the voltage for transistors and there is no harm in a transistor due to struggle more screws. The heat sink is a black anodized aluminum extrusion with fins on one side. It measures 300 mm long and has a lid that a 80mm fan cooled 24V DC. The fan runs constantly, which means that the radiator is always cool (or at least slightly above the ambient temperature).
