I — INTRODUCTION
SCOPE OF MANUAL. This instruction manual covers
the installation and operation of the Kepco JBW 15W
Series of RoHS (Reduction of Hazardous Substances)
compliant Switching Power Supplies.
DESCRIPTION. The Kepco JBW 15W Series consists of
four models of switching power supplies, with a single out-
put as shown in Table 1. Units may be operated with a
nominal 100 to 120V a-c and 220 to 240V a-c (input voltage
range 85 to 265 Va-c), 50-60 Hz (input frequency range 47-
440Hz.) They will also operate on 110V to 370V d-c input.
The JBW 15W Series employs a light weight ferrite core
with a variable switching frequency. Regulation is provided
by pulse width modulation. A FET power stage, operating in

the ringing choke converter mode provides a smooth iso-
lated d-c output. A thermistor circuit prevents excessive
turn-on current surge. Overvoltage protection is provided.
Current limiting with automatic recovery from short circuit is
featured. Units are manufactured on an open frame pc
board.
Table 1 contains specifications and operating limits of indi-
vidual JBW 15W Series models. Section II (following) con-
tains specifications and operating limits common to all JBW
15W Series Models.
