A new SMPS version with unipolar output voltage plus aux. will be available this month in the following weeks. there will be few versions with output voltage from 12V to 80V suitable for various class D or T amplifiers.

I'll wait for the new SMPS : modifying a board is not my cup of tea (as we say in french

Hi Cristi,
I've just ordered a SMPS500R (+/-54V) and was wondering whether this will work OK with additional banks of 3 x 6800uf/63V caps each per rail between it and a classDaudio amp. |

The total capacitance which the SMPS500R can accept depends on the startup time and the over-current tripping point. If the time is set longer, the capacitors can have larger value. i can use 10000uF capacitors if need, then the number of the caps can be reduced.
please contact me by mail regarding your order. |

![]() some ot the tk2050 driven amps use STA517B power chip which requires up to 48V. Can the output range be adjusted to power this chip ? also, what is the size ? thanks. |

Hi Cristi!
Ive been sniffing around in your shop, but i cannot seem to find any SMPS`s fitting my subwoofer amp. I need +- 65-75vdc for this ones at around 800-1000w. I see you mention you have some coming up. Anytime soon? |

The A1000SMPS has the default output voltage in range of +-45 to +-60V. on request, other voltage values can be provided, up to +-90V DC. also, the SMPS2000R can provide such voltages, from +-40V to more than +-100V. for this, the output voltage must be confirmed upon order, since depends on the transformer turns ratio, and can be adjusted about 10% from the value which was set.
