TRANSIENT RECOVERY:
Excursion produced by step
load change from 20% to 100% and 100% to 20@:
KDN 24-5:
100mV max., 1mS max. recovery
KDN 24-10: 200mV max., 1mS max. recovery
KDN 24-20: 1V max., 1mS max. recovery
START UP TIME:
KDN 24-5:
1.7S typ @ 115V a-c, <1S @ 230V a-c
KDN 24-10: 1.9S typ @ 115V a-c, <1S @ 230V a-c
KDN 24-20: 1.8S typ @ 115V a-c, <1S @ 230V a-c
HOLD UP TIME:
115V a-c input voltage, rated load: >20
milliseconds typical (measured from end of last charging
pulse to when output drops to 95%)
EFFICIENCY:
KDN 24-5:
87% (typ.)
KDN 24-10: 85% (typ.)
KDN 24-20: 85% (typ.)
POWER OK INDICATOR:
OFF when unit in overcurrent
protection, a-c input is off, and as follows:
KDN 24-5:
Output voltage <15V d-c
KDN 24-10: Output voltage <20.5V to 23.5V d-c
KDN 24-20: Output voltage <11 to 13V d-c
ENVIRONMENTAL CHARACTERISTICS
OPERATING TEMPERATURE:
perature derating. Do not allow the power supply vents to
become dust covered because that will decrease the cooling
efficiency of the unit and cause insulation to deteriorate.
KDN 24-5: -10°C to +70°C
KDN 24-10: 0°C to +70°C
KDN 24-20: -10°C to +70°C; start up: -10°C,
@ nominal input voltage only.
STORAGE TEMPERATURE:
-40°C to + 85°C.
COOLING:
Natural convection.
ALTITUDE:
0 to 10,000 feet.
GENERAL CHARACTERISTICS
MTBF:
Per MIL HDBK 217F (GB), 230V a-c line, 40°C:
KDN 24-5: 260,000h @ 24V d-c, 5A
KDN 24-10: 425,000h @ 24V d-c, 10A
KDN 24-20: 310,000h @ 24V d-c, 20A
OVERVOLTAGE PROTECTION:
When output voltage
exceeds OVP value (see Table 1) output is cut off to protect
the load. To reset, briefly remove, then restore, a-c input
power.
OVERCURRENT PROTECTION:
Power supply enters
hiccup mode if short circuit or overcurrent condition exists;
recovery is automatic when cause is removed.
