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. The QSeries is part of the Dimension family, existing alongside the lower featured C-Series.

With short-term peak power capability of 150% and built-in large sized output capacitors, these features help start motors, charge capacitors and absorb reverse energy and often allow a unit of a lower wattage class to be used.

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, a wide range input voltage design and virtually no input inrush current make installation and usage simple. 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”.

1. INTENDED USE

This device 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 power supply in aircraft, trains, nuclear equipment or similar systems where malfunction may cause severe personal injury or threaten human life.

This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.

2. INSTALLATION REQUIREMENTS

This device may only be installed and put into operation by qualified personnel. This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect. If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to

the factory for inspection. Mount the unit on a DIN-rail so that the output terminals are located on the top and the input terminals are located

on the bottom of the unit. For other mounting orientations see de-rating requirements in this document. See chapter

24.14. This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do

not cover ventilation grid (e.g. cable conduits) by more than 30%! Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right sides are

recommended when the device is loaded permanently with more than 50% of the rated power. Increase this clearance to 15mm in case the adjacent device is a heat source (e.g. another power supply).

WARNING

- Do not use the power supply without proper grounding (Protective Earth). Use the terminal on the input block for earth connection and not one of the screws on the housing.

- Turn power off before working on the device. Protect against inadvertent re-powering.

- Make sure that the wiring is correct by following all local and national codes.

- Do not modify or repair the unit.

- Do not open the unit as high voltages are present inside.

- Use caution to prevent any foreign objects from entering the housing.

- Do not use in wet locations or in areas where moisture or condensation can be expected.

- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.

Risk of electrical shock, fire, personal injury or death.

*) 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 shortterm duration is hardware controlled by an output power manager. This BonusPower® is repeatedly available. Detailed information can be found in chapter 24.1. If the power supply is loaded longer with the BonusPower Fig. 6-2), the max. output power is automatically reduced to 240W.

**) Discharge current of output capacitors is not included.

***) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not

guaranteed value which can be achieved. The typical value is about 56.8V.

Peak current capability (up to several milliseconds)

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 24.2.

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 connected in parallel to the power supply output.

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

Short dips will be extended to a signal length of 250ms. Dips shorter than 1ms will be ignored. 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 18.

Note: The DC-ok feature requires that the output voltage 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.
