240V 50 Hz Power Factor = 0.33, 87VA, 29 Watts
110V 60 Hz Power Factor = 0.53, 51VA, 28 Watts
Operating Voltage
Standard AC operation (CDM-570A or CDM-570AL only):
100-240 volts AC, +6%/-10% – autosensing (total absolute max. range is 90-254 volts AC)
Modem Connector
Type
IEC-60320 Type C14
Mating Connector IEC-60320 Type C13
Fuse Protection
Use two (2X) 3.15A 5mm x 20mm Slo-Blo fuses for line and neutral fusing (115V AC
operation). Fuses are contained within a fuse holder that is press-fit into the body of the
IEC power module.
