» Power Supply Unit (PSU)

The PSU is used to supply the power required by the printer in any condition and has the following features:

130W maximum continuous average power (171 W at peak) with power factor correction.
4 outputs with voltages of +5.0V, +3.3V, +12V and +32V. Operates with convection cooling when +32V output is at minimum load but the Power Supply is cooled by forced air provided by a fan in the Power Supply enclosure when the +32V output is loaded.
The Power Supply is connected directly to the Power Switch and a green LED located at the front of the Printer on the bottom left hand side.

The Power Supply operates over a voltage range as described in the following table:

Rated Voltage
100-240 VAC
Normal Operating Range
88 - 264 VAC
Functional Operating Range
80 264 VAC
Rated Frequency
50/60 Hz
Frequency Test Limits
47 -63 Hz

As explained earlier, the Power Supply provides +5.0V, +3.3V, +12V and +32V to the Main PCA with the following maximum output currents:
