GENERAL DESCRIPTION

The most outstanding features of this Dimension Q-

Series 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 Q-

Series 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 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.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 23. APPLICATION NOTES 23.1. REPETITIVE PULSE LOADING Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher short-term power demand (=BonusPower®). The short-term duration is hardware controlled by an output power manager and is available on a repeated basis.
PAGE 21
QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 23.2. PEAK CURRENT CAPABILITY Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state current and usually exceeds the nominal output current (including the PowerBoost). The same situation applies when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 23.5. CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series) Instructions for charging batteries: a) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge voltage. End-of-charge voltage 27.8V 27.5V 27.15V 26.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series unit becomes a load for the other power supplies and the output voltage can not be maintained any more. This can be avoided by utilizing decoupling diodes which are included in the redundancy module YRM2.DIODE. Recommendations for building redundant power systems: a) b) c) Use separate input fuses for each power supply. Monitor the individual power supply units. Therefore, use the Input-OK relay contact of the YRM2.DIODE redundancy module.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 23.11. OPERATION ON TWO PHASES Power Supply L1 240V +15% max. The power supply can also be used on two-phases of a three-phase-system. Such a phase-to-phase connection is allowed as long as the supplying voltage is below 240V+15%. Use a fuse or a circuit breaker to protect the N input. The N input is internally not protected and is in this case connected to a hot wire. Appropriate fuses or circuit breakers are specified in section 23.

QS3.241 24V, 3.4A, SINGLE PHASE INPUT Q-Series 23.13. MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
