Series KLN

The Kepco Series KLN is a new family of RoHS compliant, automatic crossover, low-profile, high-performance, low-cost programmable power supplies. EPICS Driver (Linux compatible) now available! New additions to the KLN Series Extended Range now include 32 models with output power ranging from 5kW to 18kW 3U high, full-rack package for 6kW. 3U high, full-rack package for 12kW. 3U high, full-rack package for 18kW. 3U high, full-rack package for 5kW. 3U high, full-rack package for 10kW. 3U high, full-rack package for 15kW. The KLN Series offers stable d-c power in: 1U high, half-rack package for 750W, 1U high, full-rack package for 1,500W 2U high, full-rack package for 3,000W. Extended Range refers to the constant power technique used to extend the operating range (see model table notes for details.) 5kW Models 10kW Models 15kW Models KLN 750W, 1500W, 3000W BROCHURE KLN 5kW, 10kW, 15kW BROCHURE KLN Extended Range 5kW to 18kW, Plus DC Racks and PDU BROCHURE Speed-controlled fans limit acoustic noise for bench top applications. For Extended Range models, programming of output voltage, current, power and voltage and current limits may be achieved by built-in LAN (LXI) digital control. GPIB, USB, Serial Port (RS 422/RS 485) and Isolated Analog are factory-installed options. For 750W, 1500W and 3000W, models, programming of output voltage, current and voltage and current limits may be achieved by analog means or by RS 485 digital control. GPIB or LAN interfaces are usually factory-installed options. Field installation Kit 219-0608 is available from Kepco to retrofit the LAN interface into a unit with the standard RS 485 interface. KLN 750W, 1500W, 3000W Power Supplies         KLN Series Extended Range Programmable Power Supply (typical): 5kW, 6kW, 10kW, 12kW, 15kW, 18kW, 3U, Full Rack Epics driver (Linux compatible)         Preassembled DC Racks can house 2, 6 or 10 KLN Extended Range models. Paralleling up to 10 racks (up to 180kW per rack) can provide 1800kW (5400A for the 80V model). Six Extended Range KLN Series in DC Rack with PDU Unique patented PDU (Power Distribution Unit) affords exceptionally easy control of the parallel configuration, including full remonte control, sequential power on/off of SUB units, and monitoring of power quality and consumption of the configuration. The KLN designated MAIN automatically detects KLN's descignated as SUB. Sub units may be powered off to save energy. Zero gap stacking allows suprior power density.

Mounting KLN Units in 19-inch Rack

Mounting one 750W 1/2-rack unit in 19-inch rack requires the RA 81-1 Rack Adapter. Two L brackets and attaching hardware are supplied with the unit. One L bracket is mounted to the U bracket supplied in the rafk adpater kit. The U bracket is then mounted to one side of the unit, and the second L bracket is mounted to the other side of the unit. The resulting configuration is one KLN with a blank filler panel (the U bracket) that can be installed in a 19-inch rack using the L brackets.

Mounting two 750W 1/2-rack Units in 19-inch Rack requires the RA 81-2 rack adapter. Two L brackets and attaching hardware are supplied with the unit. With the two units side by side as they would be installed in the rack, one L bracket is mounted to the outer side of each unit. Two shoulder screws are then installed on the inner side of one unit. The shoulder screws are then inserted in the other unit and the unit with the shoulder screws is then slid forward until the panels of both units are flush. A small bracket supplied with the rack adapter kit is used to secure the rear of the two units. The two units can now be handled as an assembly and installed directly into a 19-inch rack using the L brackets.

Mounting 1500W or 3000W units in a 19-inch Rack uses the two L brackets and attaching hardware supplied with each unit. With the L brackets attached the unit can be installed directly into a 19-inch rack.
