Puls MiniLine ML15.121 User Manual
MiniLine
1. GENERAL DESCRIPTION
A compact size, light weight, simple mounting onto
the DIN-rail and the utilization of only quality
components are what makes the MiniLine power
supplies so easy to use and install within 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 from 15W to 100W.
The supplementary MiniLine decoupling diode
module MLY02.100 allows building of redundant
systems or to protect against back-feed voltages.

INTENDED USE
The power supply shall only be installed and put into operation by qualified personnel.
This power supply is designed for installation in an enclosure and is intended for the general use, such as in industrial
control, office, communication, and instrumentation equipment. Do not use this device in aircraft, trains and nuclear

TERMINOLOGY AND ABREVIATIONS
PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .
Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d. To be defined, value or description will follow later.
AC 230V 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.
230Vac A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.

Peak current capability (up to several ms)
The power supply can deliver a peak current which is higher than the specified short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.
The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will
be discharged and cause a voltage dip on the output. Detailed curves can be found in chapter 25.1
Peak current voltage dips typ. from 12V to 7.8V At 2.6A for 50ms, resistive load
