ESCRIPTION
A compact size, light weight, simple mounting on
the DIN-rail and the quick connect spring-clamp
terminals are what makes the MiniLine power
supplies so easy to use and installs in seconds.
A rugged electrical and mechanical design as well as
a high immunity against electrical disturbances on
the mains provides reliable output power. This offers
superior protection for equipment which is
connected to the public mains network or is exposed
to a critical industrial environment.
The MiniLine series offers output voltages from 5 to
56Vdc and a power rating of up to 100W. A DC-OK
signal allows remote diagnostics.
The supplementary MiniLine decoupling diode
module MLY02.100 allows building of redundant
systems or to protect against back-feed voltages.

symbol
PE is the abbreviation for
Protective Earth
and has the same meaning as the symbol
This document uses the term “earth” which is the same as the U.S. term “ground”.
To be defined, value or description will follow later.
A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery regardless whether it is charged (13.7V) or discharged
(10V). As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50Hz
and AC 120V parameters are valid at 60Hz mains frequency.
A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.

UTPUT
This feature monitors the output voltage, which is present on the output terminals.
The signal is a source output which can feed loads up to 30mA. Loads can be a 24V relay (Rcoil < 700Ohm), a LED or
the input of a PLC system. The relays operates or the LED is on if output voltage exceeds the threshold level. A free-
wheeling diode (necessary when the load is a relay) is already included in the power supply.
