It is meant to be mounted directly on a specific 12V server power supply. Two different models are supported:<\/p>\n<ul>\n<li>DPS-800GB (Fujitsu, very loud)<\/li>\n<li>HSTNS-PR01 (Hewlett-Packard, less fan noise)<\/li>\n<\/ul>\n<p>Both are available in used condition for little money via platforms like ebay &#8211; sometimes for less than 20\u20ac. Other models may also work if they provide a compatible pinout. For more details, please refer to the <em>kSupply<\/em> user manual. Alternatively, the module can also be connected to any 12V power supply (like for example a desktop computer&#8217;s ATX power supply) by attaching cables to its screw terminals.<\/p>\n<p>The module has been designed to rapidly charge the <a href=\"http:\/\/www.keenlab.de\/index.php\/product\/kweld-ultracapacitor-module\/\"><em>kCap ultracapacitor module<\/em><\/a> for high speed welding, but it can also be used for many other applications that require a stabilized voltage at high amperage. For example, build a high current laboratory power supply from it by attaching external potentiometers for voltage and current.<\/p>\n<p>The ability of the module to operate either in constant-voltage or in constant-current modes also allows to use it as a charger for high capacity Lithium batteries. Please note, that in such a case additional protection circuitry is mandatory to safely operate these batteries, e.g. a BMS.<\/p>\n<p>With a small hardware change, the module can also operate in two quadrants and is able to transfer negative output current back to its input terminals.<\/p>\n<p>An optional <a href=\"http:\/\/www.keenlab.de\/index.php\/product\/ksupply-heatsink\/\">heatsink kit<\/a> is also available.<\/p>\n<hr class=\" hr_color\" style=\"margin:0 auto 30px;\"\/>\n\n<p>IMPORTANT NOTES:<\/p>\n<p>This article does not include output cables, as their length and termination is highly application specifc.
