Puls QT20.481 Data Sheet

Q-Series

1. GENERAL DESCRIPTION

The most outstanding features of this Dimension QSeries DIN-rail power supply are the high efficiency and the small size, which are achieved by a synchronous rectification and further novel design details.

Large power reserves of 150% support the starting of heavy loads such as DC motors or capacitive loads. In many cases this allows the use of a unit from a lower wattage class which saves space and money.

High immunity to transients and power surges as well as low electromagnetic emission makes usage in nearly every environment possible.

The integrated output power manager and virtually no input inrush current make installation and usage simple with no jumpers and switches necessary. Diagnostics are easy due to the dry DC-ok contact, a green DC-ok LED and red overload LED.

Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.

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 400V 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 disregarding whether it is full (13.7V) or flat (10V) As long as not otherwise stated, AC 380V and AC 400V parameters are valid at 50Hz and AC 480V parameters are valid at 60Hz mains frequency.

400Vac A figure with the unit (Vac) at the end is a momentary figure without any additional

tolerances included.

The QT20 series shall not be used with a DC-input voltage without consulting PULS. Check QTD20.241 for DC-input voltage. (special version for intermediate bus systems, drive systems)

7. INPUT INRUSH CURRENT

An active inrush limitation circuitry limits the input inrush current after turn-on of the input voltage and after short input voltage interruptions.

BonusPower®, short term power capability (up to typ. 4s)

The power supply is designed to support loads with a higher short-term power requirement without damage or shutdown. The short-term duration is hardware controlled by an output power manager. The BonusPower

repeatedly available. Detailed information can be found in chapter 27.1 .

Once BonusPower® has been stopped by the output power limiter, a timer disables the next BonusPower® capability. The recovery timer will start as soon as the output voltage reaches the adjusted value again, which usually happens after the load has been reduced.

BonusPower® recovery time

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 causes a voltage dip on the output. Detailed curves can be found in chapter 27.2.

10. DC-OK RELAY CONTACT

This feature monitors the output voltage, which is produced by the power supply itself. It is independent of a backfed voltage from a unit which is connected in parallel to the power supply output.

Contact closes As soon as the output voltage reaches the adjusted output voltage. Contact opens As soon as the output voltage dips more than 10% below the adjusted output voltage.

Contact re-closes As soon as the output voltage exceeds 90% of the adjusted voltage. Contact ratings max 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A resistive load min 1mA at 5Vdc min. permissible load Isolation voltage See dielectric strength table in section 20

Short dips will be extended to a signal length of 250ms. Dips shorter than 1ms will be ignored.

Note:

The DC-ok feature requires that the output voltage

10%

reaches the nominal (=adjusted) level after turn-on in order to function according to specification. If this level cannot be achieved, the overload lamp will be on and

the DC-ok contact will be open. The overload signal will only shut off as soon as the adjusted voltage is reached. This is an important condition to consider particularly, if the load is a battery, the power supply is used in

parallel or the power supply is used for N+1 redundant systems.
