Half Bridge resonant SMPS capable of delivering 300W continuous and up to 400W peak power. It is configured for single output voltage in range of 24V to 72V plus one differential output voltage of +-12V or +-15V at 500mA max. current. The stock available output voltages are adjustable within approx. 10% and the ordered voltage value is at the middle of the interval. For example the 24V version can be adjusted from 22.5V to 26V. In this way, the available voltage versions covers almost all the voltage range from 22V to 50V. It uses zero-voltage switching half bridge resonant topology. The main feature of this power supply is the absence of the heatsinks both for power switches and rectifier diodes, due to increased efficiency, up to 94.6% for higher voltage versions, due to the fact that the transistors are soft-switched, and the current through the switches has sinusoidal shape, and there are no additional losses in output inductors. Also, the amount of EMI is much less than any conventional power supply, and could be compared with a linear well regulated power supply. The size and weight is greatly reduced, allowing to install the SMPS300R to be installed into low profile case, with it's 100x100mm and 32 to 40mm tall depending on the voltage version and capacitors used. The SMPS300R features over-current protection which limit the output current at about 130% of the maximum peak power, about 400W. This power supply is suitable for both class AB and class D/T amplifiers, which have the PSRR greater or at least 54dB. Target applications for this power supply unit are class D BTL output amplifiers. * Any other voltage than available ones can be supplied on request, in range of 18V to 180V for the single voltage version. Due to the fact that custom voltage require custom transformer, and some component changing, it cost more and it can take one-two weeks more to be done.
