KEPCO SERIES KLP

Using high-frequency switch-mode topology for high
efficiency and small size, the KLP provides 1200 watts
of well-regulated, controllable d-c power in a 1U
(1.75 inch high) by 19 inch rack-mountable package.
KLP replaces the need for multiple power supplies
by expanding the operating region. The breakthrough
of a hyperbolic power limit delivers a full 1200 Watts
over an expanded operating range, not just the
conventional rectangular operating area.

Circuit

all KLP/KLR models. This circuit rapidly discharges the output capacitance,
thus significantly reducing response time to reductions in output voltage.

The circuit consists of a voltage detector that compares the programmed
and actual values of output voltage. The discharge circuit is activated only
when the actual voltage exceeds the programmed value.

Without the RODC circuit, discharge of the total output capacitance
(internal and external) is achieved through a combination of the external
load resistance and an internal current sink. For high load resistance or
open circuit conditions at the output, response time (fall time) can vary
from hundreds of milliseconds to seconds depending upon the magnitude
of the high-to-low voltage transition.

With the RODC option, output fall time is reduced to approximately the
same value as rise time, even with external capacitance equal to 50%
of the nominal internal output capacitance.

Please see the website for details about this option.

Looking For More High Power, Low Prole Power Supplies?

SERIES KLN

The Kepco Series KLN is a new family of automatic
crossover, low-profile, high-performance, low-cost
programmable power supplies. The KLN Series offers
stable d-c power in a 1U high, half-rack package for
750W, a 1U high, full-rack package for 1500W and
a 2U high, full-rack package for 3000W. A total of
39 voltage-current combinations are offered. Output
voltages range from 0-6 Volts to 0-600 Volts and
output currents range from 0-400 Amps down to
0-1.25 Amps. Speed-controlled fans limit acoustic
noise for bench-top applications when full power is
not needed.

Precise programming of voltage, current and their
limits may be achieved from the front panel, or by
analog means or by RS 485 digital control. GPIB
or LAN interfaces are factory-installed options.
