Table 14. Power specifications
Specification Value
Input voltage A fully loaded switch requires a maximum of
750 Volt-Amps This results in a main current
of 3.2 amps at 240 V ac line voltage or 3.6
amps at 208 V ac line voltage. The rated ac
input range is 180 to 264 V ac.
Supported power range 200–240 V ac, single phase
Input frequency range 47–63 Hz
Power supplies (each) Output voltages: 48 V at 20 amps; 12 V at 4
amps
Maximum output power: 1000 watts
Maximum ac inrush current per power cord 40 amps, peak
Ride through The supply outputs remain within specified
regulation for a minimum of 20 msec after
the ac mains are disconnected.
Under voltage protection The M14 power supply self-protects from any
input voltage, static or dynamic, from zero
volts to its operating ranges. It recovers to
normal operation upon returning to its
operating range.
Environmental requirements
Table 15 lists the environmental operating ranges for the 2109 Model C36 with
Model M12 or M14. The requirements for non-operating conditions are also
provided for acceptable storage and transportation environments.
