1. Overview
Kontron’s power supply unit family
includes both AC and DC input power
devices with up to 12HP front panels
and 3U in height. The devices are pro-
vided with P-series or DIN M-series out-
put connectors.
The power supply units can be provided
for an output power range of 75 W to
200 W for AC/DC power supply units
and 75 W to 200 W for DC/DC power
supply units with output voltages of
+ 3.3 V, + 5.1 V, and either + 12 V or
± 12 V.
2. Distinctive Features

• Plug-in compatibility
• Input voltages
• Voltage switching
(AC devices)
• Output power
• Output voltages and currents
• Power supply connector
• Cooling
• Redundant supply capability
• Status indication
• Special features:

either according to their form factor: 3U
and up to 12HP where the P-series is
8HP (4.064 cm or 1.6 inch) and the M-
series is 12HP (6.96 cm or 2.4 inch) or
input voltage (alternating current, direct
current).
Input Voltages
Power supply units running on AC input
power are provided with a switching fea-
