Value
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.
200–240 V ac, single phase
47–63 Hz
Output voltages: 48 V at 20 amps; 12 V at 4
amps
Maximum output power: 1000 watts
40 amps, peak
The supply outputs remain within specified
regulation for a minimum of 20 msec after
the ac mains are disconnected.
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.
