TELE Catalogue - Tele Haase Steuergeräte - #9

The products more than over fulfil the requirements specified in the standards for bursts and surges for this equipment. This guarantees reliable operating safety even in areas of high electromagnetic noise level. A distinction that makes a difference. The temperatures in which the devices may be used range from -25 to +55°C. The generous front operating panel provides much space for the installation of setting and display elements. Thus enabling clear displays with separate LEDs for all operating needs. There is only one rule that has been followed at TELE for many years: flashing LEDs mean "time running", permanently lit LEDs mean "time expired". The operating elements are arranged on the front whereby up to five controls may be comfortable accessible in a unit of 22.5 mm width only. This allow highest functionality using smallest space. CoolZoom with 24-240 VACDC and power modules with rated voltages of up to 400V(TR2) and 500V(TR3) are available for auxiliary voltage supplies. The functional concept of the WatchDogs migrate now to installation equipment by the new range of ENYA monitoring devices. The comfort of up to four controls in a one module housing of 17.5 mm width is accompanied by up to four display elements. These are used for diagnostic displays for ongoing operations, for instance, to determine which phase has failed. Devices in the ENYA range will find sufficient space in any power-distribution cabinet and are therefore highly suited for use with automation and control engineering in buildings. They may also be used to provide protection against undesirable operating states, to detect activated loads and to carry out classical control tasks. The applications here range from the monitoring of distribution networks through single-phase monitoring tasks to the monitoring of direct currents in battery-buffered systems. A variety of power and voltage sensor relays are available in single- and three-phase designs. The units are "self - powered " by the measuring circuits to reduce the number of terminals and required connections. A horizontal module of 17.5 mm was selected as the width for this voltage supply design; the versions with separate auxiliary voltage supply have been installed in housings with 35 mm width. As usual, the asymmetric arrangement of the terminals in the installation series enable to connect wires in both layers of terminals in any sequence. It is easy to even change the wiring of the back layer on installed units.

^^^^^^ WatchDog sensor relays have the capability ^^JV^/xV to monitor the thresholds for such electrical ■ /(jj^j^ll g values as current, voltage, power factor, active \ \Jc==^ 9 power, conductivity, resistance, temperature ~ and so on, which in turn enables the generation

of corresponding signals in the event of deviations. The new consistent operating and functioning concept of the new GAMMA series' simplify operation and increase "functional safety' at the same time. They need less space and are more universal than their predecessors in the successful VOX range. The case appearance already is an evidence for their use in harsh industrial environment. All units meet the requirements of overvoltage-category III as it is required for equipment for use in industrial environment.

You can tailor the WatchDog monitoring relays and load monitors, as well as the GAMMA range's timing relays simply, consistently and economically to the relevant supply voltage simply by connecting one of a range of plug-in power modules covering a voltage range from 12V to 400V AC to the power supply slot on the side of the device.

The TR2 power modules with selectable rated voltages from 12 to 400VAC fit to the units with a width of 22.5 mm while the TR3 power modules with rated voltages of up to 500V have been designed for units of 45 mm width. The supply voltage may therefore also be taken from the phase to phase voltage if the application is planned without a neutral connection. The power modules work particularly „quietly" in the mains, which means that they are entirely suitable for Class B applications in accordance with EN 55011 (residential). An additional benefit: in the event of any maintenance being required, the plug-in power module may be quickly and comfortably replaced. Just place a separate order with the plug-in power module you order for your application.
