Puls QTD20.241 Data Sheet

Q-Series

1. GENERAL DESCRIPTION

Modern machines typically use maintenance-free ACmotors which are controlled by frequency converters or servo amplifiers. Such devices have an intermediate DC-bus where all individual drives are connected. The QTD20 power supply can be connected directly to the intermediate DC-bus. In case of a mains failure, the QTD20 utilizes the kinetic energy from the motor and the DC-bus capacitors to keep the controls and other important peripheral equipment operational until the motor is in a complete stop position. With the QTD20 mains failure can be handled with no problems. Intermediate DC-buses are not usually filtered and have high EMI noise superimposed. The QTD20 has a very robust input stage and an appropriate input

filter included.

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.

DC 600V 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)

600Vdc A figure with the unit (Vdc) at the end is a value which is used during testing without any

additional tolerances included.

DISCLAIMER

BonusPower®, short term output 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 26.1 .

Once BonusPower® has been stopped by the output power limiter, a timer disables the next BonusPower® capability.

This timer (recovery time) will start as soon as the output voltage reaches the adjusted value again, which usually

happens after the load has been reduced.

9. DC-OK RELAY CONTACT

This feature monitors the output voltage, which is produced by the power supply itself. It is independent of a back-

fed 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.

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 LED 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

openclosed closed

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