PS1260 Rittal 6U x 24HP Power Supply Backplane

The Kaparel PS1260 / PS1265 are 6.5U (or 6U) tall, 24HP wide power backplanes. They may be used with the PS1300, PS1400, or PS4400 series of modular CompactPCI backplanes, or in any other application where large supply currents are required. Both will accept up to three Positronic type 500W power supplies operating in current sharing mode. The PS1260 and PS1265 support different power supply styles. The PS1260 supports the standard Positronic style used by most cPCI power supply vendors, including Kaparels PS335x and PS535x series of power supplies. The PS1265 supports the special “High Profile Cooling Fin” style available from some vendors.

Either AC or DC power is supplied to the power plane by means of two six-contact Mate-n-Lok connectors. There are 8 ATX-style power connectors on each of the PS1260 and PS1265, for distribution of PS1600 Cable Assembly regulated power to Kaparel's modular CompactPCI backplane families. The connectors used are Molex “Mini-Fit Jr.” series headers or compatible connectors. These are the same connectors that are recommended for ATX style PC power supplies. The CompactPCI backplanes will be connected to the power backplanes by means of cable assemblies (such as Kaparel's PS1600) with mating “Mini-Fit Jr.” receptacles at either end. Both backplanes also have several rows of power taps for use when large supply currents are required, or when ATX connectors cannot be used. There are 26 power taps per board, connected to various output voltages. PS1260 6U x 24HP: The PS1265 is the same board as the PS1260, only with its power supply connectors offset to the left to accommodate PICMG 2.11 power supplies (see below).
