I — INTRODUCTION
SCOPE OF MANUAL. This instruction manual covers
the installation and operation of the Kepco JBW 10W
Series of RoHS (Reduction of Hazardous Substances)
compliant Switching Power Supplies.
DESCRIPTION. The Kepco JBW 10W Series consists of
five 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 10W Series employs a light weight ferrite core
with 100 KHz switching frequency. Regulation is provided
by pulse width modulation. A FET power stage, operating
in the flyback mode provides a smooth isolated 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 10W Series models. Section II (following) con-
tains specifications and operating limits common to all JBW
10W Series Models.
II — SPECIFICATIONS
The following specifications are at nominal input voltages
and 25°C and apply to all models unless otherwise speci-
fied.
INPUT CHARACTERISTICS:
INPUT VOLTAGE: (0 to 100% load, -10 to 60°C)
Nominal 100-240V a-c, 220-240V a-c
Range: 85-265V a-c
INPUT SOURCE FREQUENCY:
Nominal: 50/60 Hz;
Range: 47-440 Hz
INPUT CURRENT: (100% load at 25°C with nominal out-
put voltage):
100V a-c input: 0.25 typ., 0.35 max.
240V a-c input: 0.15 typ., 0.25 max.
INPUT PROTECTION AND SOFT START: A thermis-
tor circuit reduces start-up surge. Units are protected
against shorts by an input fuse. Fuse value 2.0A, 250V.
INPUT SURGE: Cold start:
100V a-c input, 100% load: 15A typ, 20A max.
240V a-c input, 100% load: 30A typ., 40A max.
