1000W, 1500W HSM Watt Power Supply Models
Series HSM
The Kepco HSM series comprises a group of ten models, seven 1000 watt power supplies with outputs from 3.3 volts to 125 volts and three 1500 watt power supplies with outputs from 24 to 125 volts. All models feature current sharing for parallel operation and redundancy applications. Kepco¹s 1000W HSM have a wide-range input (90-277V a-c). The 1500W models operate 180-277V a-c. Both incorporate power factor correction to meet EN 60555-2 and EN 61000-3-2. These modern power supplies operate at 100KHz using current mode control to provide rapid response to source and load changes and tight stabilization.

1000W Ferroresonant Power Supply
Series PRR
Kepco's PRR are 1000 Watt rack mounted laboratory systems power supplies that offer the low cost and very high dependability of ferroresonant voltage stabilization.The ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. It is inherently short-circuit proof and cannot expose delicate loads to overvoltage hazards. Hence no crowbar, fuses, or bounding circuits are needed. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references and requires no comparators, references, or limiters. Efficiency is 70-80%.

1200W Constant Power DC Power Supplies
Series KLP
The KLP is an entirely new laboratory grade power supply in which the voltage/current limits are automatically recalculated, forming a constant-power hyperbolic-shaped boundary between the voltage and current modes. This curve, which replaces the single max-power operating point of conventional power supplies, provides the user with a greatly expanded choice of maximum power volt-ampere combinations as illustrated in the diagram by points A to B to C. The constant-power limit of the KLP is 1200 watts.

1U Rack Adapter for Series HSF-1U, HSF-1UR
RA 19
The 1U high rack adapter will mount four of the low profile 50W, 100W and 150W (Series HSF-1UR or HSF-1U) power supplies. Each plug-in power supply is equipped with a power on/off, indicator LEDs and voltage test points. The RA 19-1U provides access to the DIP switches and rack keying without disassembling the rack. It also provides a redundant scheme with modules 1 and 3 being powered from one a-c input and modules 2 and 4 from a second a-c input. Module numbering is left to right facing the front panel.

Automatic Crossover, 1U High, 2400-Watt Voltage/Current Stabilizers
Series KLR
The KLR Power Supply Series are automatic crossover, 1U high, 2400-watt voltage/current stabilizers with a full rectangular output characteristic within the voltage and current ranges listed in the Models Table.For each model a multitude of limit models can be configured. Limit models allow the unit to be configured to maximum settings below the rated voltage and/or rated current. When a limit model is established the unit will not accept programming values above the user-defined limits.The standard KLR Models (no suffix) have built-in GPIB and RS 232 interfaces. The E-Series models (suffix E) have built-in GPIB and LAN interfaces. The LAN interface is an ethernet-based interface that allows multiple-user access via a standard web browser.

Bipolar Power Supplies High Power, 4-quadrant, Analog/Digital/Local Control, Low Ripple/Noise
Series BOP-MG/ME, BOP-EL/GL
The BOP High Power are true 4-quadrant programmable voltage and current power supplies. 4-quadrant operation means that they are capable of both sourcing and sinking power. These bipolar power supplies pass smoothly through zero to provide ± voltage and ± current. The BOP High Power use switch mode technology for low dissipation and function as regenerative (recuperative) loads and connected to an active load.

Electronic Loads
Series EL
The EL Series is a line of modular aircooled, DC electronic loads used to test power sources such as batteries, power supplies, generators, chargers, fuel cells, etc.Power ratings start at 1KW; standard models have maximum test capabilities of 50, 200, 400 and 600 volts. High current and power operation are achieved via parallel connection in a master/slave configuration. Individual modules are capable of up to 5KW and 800 amperes.

Lightweight, Compact, Fully Enclosed/Shielded Power Converters
Series RKE
These lightweight (less than 7 lbs.), compact (less than 160 cubic inches), fully enclosed/shielded power converters deliver either 24, 36 or 48 volts d-c, to run distributed power systems, motors, actuators or heaters. Their universal a-c input (85-265V a-c) is at home with either 115V a-c or 230V a-c, though they produce significantly more output at the higher input voltage, and should be run from 200-240 volt mains wherever possible.
