ESCRIPTION

The Dimension C-Series are cost optimized power

supplies without compromising quality, reliability and

performance. The C-Series is part of the DIMENSION

power supply family. The most outstanding features of

CT5.241 are the high efficiency, electronic inrush current

limitation, active input transient filter and wide

operational temperature range, the small size and other

technological design concepts.

The C-Series includes all the essential basic functions.

The devices have a power reserve of 20% included,

which may even be used continuously at temperatures

up to +45°C. The CT5.241 utilizes only 2 legs of a 3-

phase system which saves wiring and installation costs.

Furthermore, this allows a smaller unit without

compromising the size of the terminals. Due to the low

power consumption, an unbalancing of the individual

phases is not expected.

The two aluminum brackets and the black plastic slider of the unit have to be detached, so that the steel brackets can be mounted in the holes of the aluminum brackets. The order number ZM1.WALL contains two brackets needed for one device. Fig. 21-1 ZM1.Wall Fig. 21-2 Hole pattern Fig.

ZM12.SIDE - SIDE MOUNT BRACKET This ZM12.SIDE bracket is used to mount the device sideways with or without utilizing a DIN rail to save installation depth. The two aluminum brackets and the black plastic slider of the unit have to be detached, so that the ZM12.SIDE steel bracket can be mounted. For sideway DIN rail mounting, the removed aluminum brackets and the black plastic slider need to be mounted on the ZM12.SIDE steel bracket. Fig.

The device is equipped with two input channels each 10A nominal, which are individually decoupled by utilizing diode technology. The output can be loaded with nominal 20A. The device does not require an additional auxiliary voltage and is self-powered even in case of a short circuit across the output.

PEAK CURRENT CAPABILITY The unit can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents. This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil.

Two 12V SLA or VRLA batteries are needed in series connection. Instructions for charging batteries: a) Ensure that the ambient temperature of the power supply stays below 45°C. b) Set the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-ofcharge voltage. End-of-charge voltage 27.8V 27.5V 27.15V 26.

CT5.241 3-PHASE, 24V, 5A, 120W CT-Series 22.3. SERIES OPERATION Unit A Devices of the same type can be connected in series for higher output voltages. It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc must be installed with a protection against touching. Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals.

CT5.241 3-PHASE, 24V, 5A, 120W CT-Series 22.5. PARALLEL USE FOR REDUNDANCY 1+1 Redundancy: Devices can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case one device fails. The simplest way is to put two devices in parallel. This is called a 1+1 redundancy. In case one device fails, the other one is automatically able to support the load current without any interruption.

USE IN A TIGHTLY SEALED ENCLOSURE When the device is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher than outside. In such situations, the inside temperature defines the ambient temperature for the device. In the following test setup, the device is placed in the middle of the box, no other heat producing items are inside the box. The load is placed outside the box.

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 listed lifetime and MTBF values from this datasheet apply only for the standard mounting orientation. The following curves give an indication for allowed output currents for altitudes up to 2000m (6560ft). Fig.
