I — INTRODUCTION
SCOPE OF MANUAL. This instruction manual covers
the installation and operation of the Kepco JBW 100W
Series of RoHS (Reduction of Hazardous Substances)
compliant Switching Power Supplies.
DESCRIPTION. The Kepco JBW 100W Series consists
of four models of switching power supplies, each with a sin-
gle output as shown in Table 1. Units may be operated with
a nominal 100 to 120V a-c and 220 to 240V a-c (input volt-
age range 85 to 265 Va-c), 50-60 Hz (input frequency
range 47-440Hz.) They will also operate on 120V to 370V
d-c input. The JBW 100W Series employs a light weight fer-
rite core. Regulation is provided by pulse width modulation.
Power Factor Correction (PFC) is provided by a boost con-
verter operating at 80kHz. A FET power stage, operating
as a forward converter with a fixed switching frequency of

INPUT CHARACTERISTICS:

INPUT VOLTAGE: (0 to 100% load, -10 to 60°C)
Nominal 100-120V a-c, 220-240V a-c
Range: 85-265V a-c, 120 -370V d-c
NOTE: The power supply may shut down if operated at
below the input voltage range or if the input voltage
increases slowly at start up (> 1 second). To reset the
power supply, unplug the unit, wait one minute and
reapply input power.
INPUT SOURCE FREQUENCY:
Nominal 50/60 Hz;
Range 47-66 Hz (Above 66Hz to 440 Hz the leakage
current may exceed the VDE safety specification limit.)

150kHz provides a smooth isolated d-c output. A thermistor
circuit prevents excessive turn-on current surge. Overvolt-
age protection is provided. Current limiting with automatic
recovery from short circuit is featured. Units are manufac-
tured on an open frame PC board.
Table 1 contains specifications and operating limits of indi-
vidual JBW 100 Series models. Section II (following) con-
tains specifications and operating limits common to all JBW
75W Series Models
