Dual Linear Supply board equipped with 4 High quality electrolytic capacitors chosen with values between 2200uF and 27,000uF at working voltage between 35V and 100V. It has two 6.8uH Inductors between each rail capacitors as well as 4 high-frequency snubber to filter furthermore the high-frequency noise which can affect the sound quality. It has two LED’s, one for each polarity and separate input-output fast-on type terminal type connectors which can be used to connect thick wires up to 4 sq mm.
The LPS212A has no rectifier bridge on-board and must be used between an existing SMPS and one or two amplifier boards as a CLC filter which also increase the total available capacitance. It can be used for any class AB or D amplifier which requires smooth DC rails as well as higher capacitance per rail than the existing power supply can provide. When LPS212A must be used with a medium power SMPS such as SMPS240R, SMPS300RE or SMPS500R(xE) when higher peak power than the SMPS can provide is required or the amplifier supplied from these power supplies is used for subwoofer applications mainly.
The LPS212A board size is just 72x100mm and and the height depends on the capacitors height, with the lowest profile capacitors, 25mm tall the overall height will be just 32mm including 5mm space below board. The PCB board layout is optimized for lowest ESL and excellent behaviour from DC to multi-MHz frequency range, PCB uses 2oz copper thickness for high current capability. LPS212A uses only high-quality, genuine, new and original capacitors carefully chosen from series with low ESR/ESL, high ripple current and long-life type. Example: Panasonic HC Series, Nippon Chemi-con LXG Series, Elna LAH Series, Nichicon GU Series.
The listed price is for the complete assembled board with all the parts except the four Electrolytic capacitors who’s price will be added from the drop-down menu upon choice.
