I — INTRODUCTION
SCOPE OF MANUAL.
This Quick Start Guide covers
the installation and operation of the Kepco RKW Series of
PFC (Power Factor Corrected), RoHS (Reduction of Haz-
ardous Substances) compliant, programmable switching
power supplies. Full specifications are listed in the applica-
ble Operator’s Manual that can be downloaded from the
Kepco web site:

DESCRIPTION.
The Kepco RKW Programmable Series
switching power supplies come in 300W, 600W and 1500W
sizes (see Table 1). Each size has 3.3V, 5V, 12V, 15V, 24V,
28V and 48V models.
Units may be operated with a nominal 100V a-c to 240V a-
c (input voltage range 85 to 265 Va-c), 50-60 Hz (input fre-
quency range 47-66Hz). They will also operate on 110V to
370V d-c input. Overvoltage, overcurrent, overtemperature,
fan failure and power failure protections and an isolated
remote TTL ON-OFF control are provided for all models.
An LED “output voltage ON” light and an output voltage
adjust trimmer are provided.
II — INSTALLATION
MOUNTING THE POWER SUPPLY:
Refer to Figure
1. The unit may be mounted on one mounting surface. Note
the restrictions for maximum penetration of mounting
screws (M4): 0.24 in (6 mm) from case. The air surrounding
the power supply must not exceed the ambient values
given in the graph in Figure 4.
CONNECTIONS:
Figure 2 shows proper connection of
one or more loads using either remote or local sensing.
If
local or remote sensing is not configured, the unit will
not work properly.
The unit is shipped with local sense
cables in place for Local sensing. For remote sensing,
remove the local sense cables and connect the +S and –S
terminals to the load. Remote sensing compensation is up
to 0.4V per load wire (0.15V for 3.3V models, 0.25V for 5V
models). Transient recovery specs may not be met when
remote sensing is used. If oscillations set off overvoltage
protection, install one electrolytic capacitor (470
µ
F min)
bS and + and one between – and –S terminals.
The AC input power is applied via the terminal block. Make
sure to connect the AC input Neutral, Line and Ground
wires to the respective terminals of the terminal block (see
Figure 3).
Sensing (either Local or Remote) MUST be
used.
