I — INTRODUCTION
SCOPE OF MANUAL. This instruction manual covers the
installation and operation of the Kepco KDN Series of RoHS
(Reduction of Hazardous Substances) compliant 24V
Switching Power Supplies.
DESCRIPTION. The Kepco KDN 24V Din Rail Series con-
sists of three models of switching power supplies rated at 5A,
10A and 20A, each with a single 24V output as shown in Table
1. Units may be operated with a nominal 100V a-c to 240V a-c
(input voltage range 90 to 264 Va-c), 50-60 Hz (input fre-
quency range 47-63Hz. These units employ active PFC
(Power Factor Correction) using ZVS (Zero Voltage Switch-
ing). Overvoltage protection and current limiting with automatic
recovery from short circuit are featured. Units are convection
cooled.
II — SPECIFICATIONS
The following specifications are at nominal input voltages and
25°C and apply to all models unless otherwise specified.
INPUT CHARACTERISTICS:
INPUT VOLTAGE:
Nominal 100-240V a-c,
Range: 90-264V a-c, 125-370V d-c: polarity insensitive.
NOTE: Safety agency approval applies only to a-c input
operation.
INPUT SOURCE FREQUENCY:
Range 47-63 Hz (Units operate up to 440 Hz, however the
leakage current exceeds the UL leakage safety specifica-
tion limit, and power factor and efficiency specifications
may not be met.))
INPUT CURRENT:
KDN 24-5: <2A @115V a-c, <1A @ 230V a-c
KDN 24-10: <6A @115V a-c, <2.6A @ 230V a-c
KDN 24-20: <10A @115V a-c, <5A @ 230V a-c
INPUT PROTECTION: Units are protected against shorts
by an input fuse. Fuse value 10A, 250V.
INPUT SURGE: An inrush current liming resistor reduces
start-up surge. Cold start 25 °C:
30A max. @ 115V a-c, 60A max. @ 230V a-c
LEAKAGE CURRENT:
Line to ground, input: 115V a-c, 60Hz
KDN 24-5: <0.2mA
KDN 24-10: <0.25mA
KDN 24-20: <0.35mA
POWER FACTOR: Meets EN 61000-3-2, Class D
115V a-c: 0.99
130V a-c: 0.95
SWITCHING FREQUENCY:
KDN 24-5: 120KHz
KDN 24-10: 120KHz
KDN 24-20: 62KHz

(1) One minute minimum duration @ 25°C ambient. The total RMS output current and power shall be kept within rated values.
(2) Bandwidth 15 MHz. Full load, nominal line, output terminated with 0.47 µ F capacitor.
(3) To restart (reset) the unit, removed a-c input power, wait approximately 40 seconds, then restore a-c input power.
(4) Hiccup mode with auto recovery.
