Pioneer Magnetics is continually designing and manufacturing racks/power shelves along with associated hot-plug connector options for standard and custom requirements. From 3U to 1U configurations or other shapes and sizes, PMI provides a non-stop, easy swap out, labor saving process for those applications requiring rack mounted power shelf products. In addition, many PMI system products offer “Intelligence” or, what we call, “System Intellect Capabilities.”
A TRUE HOT PLUG REDUNDANT POWER SYSTEM
19”, 23” & 30” POWER SHELF
♦ Pioneer Magnetics’ True Hot Plug Power System eliminates down time by providing glitch-free, continuous operation for critical systems that must not fail. A standard line of high reliability switching power supplies is combined with an industry standard 19" or 23" rack to create an advanced hot plug system.
♦ True Hot Plug eliminates all switches and breakers. The system never shuts down. Less than 10 seconds is required to remove and replace a supply. Power supplies can be swapped at full system power by simply pulling any unit out of the rack and plugging in a replacement.
♦ With a common 5" x 5" cross-section, Pioneer power supplies are available from 1kW Watts to 8.1kW. Standard output voltages are 12VDC to 60VDC. All supplies offer Power Factor Correction to 99.9% in Single Phase AC input or 95% in Three Phase AC input. Built-in single wire paralleling gives excellent load division among supplies, regardless of the number of active supplies. Load is automatically distributed as supplies are removed or added. Wireless (Droop) current sharing provides greater reliability.
♦ The PM1450 rack series offers unusual flexibility and capacity, while providing a complete power system solution. Up to three 5" x 5" supplies are housed in a 19" rack, and up to four supplies in the 23" rack. This means that four 8100-watt supplies can provide 32.4kW of power in a single 23" rack. Stacking up five shelves can supply 162kW Watts of redundant power in just 31.5" of rack height. Custom system expansion and future upgrade capacity are readily available.
KEY FEATURES OF TRUE HOT PLUG
♦ The guarantee of practically unlimited freedom from shut down. A single Pioneer power supply has a DMTBF of about½ million hours. Redundancy gives a System DMTBF of over 100 million hours or 10,000 years.
♦ A Redundant System (Each supply can carry the full load, or share the load with a second or third supply).
♦ No Switches or Circuit Breakers on the Input or Output side.
♦ No deviation or loss of Output Bus Voltage during insertion or removal of units.
♦ Zero Down Time.
♦ A special customized design combination of Pioneer Magnetics’ Hot Plug Power Supply and Elcon Top or Lower Drawer Connector.
♦ High Power Density to 21watts/in3.

Pioneer Magnetics is the Hot Plug power supply specialist. PMI was the first power supply company to design and use a “Hot Plug Connection.”
We certainly have come a long way!!
