2000VA Hand Made Toroidal Transformer 2kW Amp 110V 115V 220V 230V 240V Amplifier



30A 100V 35000uF Fast Recovery Rectifier Capacitor Bank Board - L




It is a Class D audio power amplifier board producing full range up to 2500W @ 2 Ohm continuously. An IRS2092 controls six IRFB4227 HEXFET® power MOSFETs to deliver power effortlessly and achieve extreme efficiency up to 91%. The robust heatsink on board provides enough cooling for most applications.

High reliability is ensured due to a myriad of protection features such as over current, over/under voltage, DC output and built-in temperature protection. Resistance and capacity components of high quality, including Metallized Polyester (PET) Capacitors and lower ESR electrolytic capacitors, high performance inductors are used to gain the perfect timber, finally realizing high S/N ratio, low THD+N, wide frequency response range etc.

Note: Two 60 to 94 VDC high-voltage power supplies are required for operation; each power supply dedicates its full output potential to a single rail for maximum output. This results in increased high-fidelity output, high dynamic range, low distortion, and a wide 20 to 22,000 Hz frequency response. This amplifier board is recommended for experienced users only with the proper equipment to measure the voltage output of the power supplies. Failure to use the minimum recommended power supply voids the warranty of this amplifier board. After removing power from the amplifier board, it is recommended that you allow 20 seconds for all stored power to dissipate before turning the amplifier on again. Failure to do so will result in a turn-on pop.
