Suppressor Module

LÜTZE’s philosophy is to supply an appropriate, easy to integrate suppression solution for all contactors commonly used in rail vehicles. So our product range now contains numerous versions for different types and voltages, most of which can be mounted directly on the contactor. For example our S7A model, which among others can be mounted directly on to AEG Type LS4, LS7, SH4, SH8 and SH14 as well as various ABB types, and is used in thousands of applications.

Triple Diode Module with 6.2 mm width

LÜTZE diode modules are an universal aid when it comes to saving space when using decoupling or freewheeling diodes. The wired version helps to minimise the wiring, e.g. when decoupling interference signal systems. Wirable versions with up to 22 individual diodes offer maximum flexibility for the widest range of applications, e.g. the Lütze triple diode module 762068: it requires minimum space on the top hat rail, just 6.2 mm, and yet it provides three wirable diodes of type EM513 (1 A/1600 V), which can be connected via spring-type terminals.

Sixfold Diode Module

Optimum wiring options are provided by three plug-in spring-type terminals available to each pole of the six wirable diodes on this diode module. At a width of just 22.5 mm, it is possible to resolve many suppression or decoupling tasks which would otherwise require complex wiring via the terminal block.

Module Racks

These modules resolve numerous installation problems in the simplest way possible. They form the base for installing resistors, diodes or special function relays on to the top hat rail. At the same time they provide a secure connection via the integrated spring-type terminals. To ensure that everything fits in the best way possible, different models are available with a variable number of connection points and insertion locations.

Relay Module

• Available with pluggable or integrated relay. Each module contains a change over contact with spring-type terminal which can be wired from above (top connector)
• For the connection of different switching groups or for applying of potential layers each connector also has a contact for jumper combs. This ensures a simple and well arranged wiring
• Available for all regular on-board voltages

Relay Module with Positive-Action Contacts

• The relays are compliant to the standards EN 50205, IEC/EN 60255 and IEC 60664-1 and are therefore suitable for safety-relevant applications
•  For the different areas of application, the relays can be supplied with 2 (1NO/1NC) to 8 contact sets (7NO/1NC). The contact sets are positivelydriven and thus offer the maximum safety. All air and leakage distances are designed to be 5.5 mm and thus offer a significantly improved isolation
• Available for all regular on-board voltages

Timing Relay with Dropout Delay

• An integrated microcontroller makes it possible: This timing relay is supplied with the parameters you require ex works. There is no need to time-consuming adjustment of selection switches or potentiometers during commissioning. As there are no operating elements, there is no possibility of manipulation during operation.
• Wide range power supply and wide range control voltage allow operation on all standard on-board voltages between DC 24 V and DC 110 V
• Should changes to the time function become necessary during operation: No problem, the time relay can be reconfigured at any time using an integrated programming interface

25 A Transistor Switch

• Mechanical switching elements that are operated frequently require regular maintenance; contacts can burn out where there are high currents in DC operation and inductive loads. Non-contact switching elements such as these 25 A semiconductor switches provide a remedy
• LÜTZE can offer semi-conductor switches up to 100 A switching current for all kinds of tasks and for all current on-board power supplies
• Optional diagnostic output for short-circuit, overload and wire break simplify troubleshooting and increase availability

Transducers

In order to connect the different analogue signals inside a vehicle to the control technology, LÜTZE offers a range of transducers which are exactly tailored to rail vehicle requirements. The transducer for monitoring the on-board electrical system enables the on-board voltage of DC 0-200 V to be monitored using one control input for signals from 0-10 V. At the same time it provides galvanic isolation between the on-board voltage and the measurement signal.

Compact Regulator for windscreen/floor heating

By combining the temperature regulator and power amplifier in one unit the compact regulator fulfils the three important requirements of LÜTZE rail components:

• Efficient: The power amplifiers are connected directly to the temperature regulators. All that’s left is to connect the PT1000 sensors and heating elements, no complex wiring is required between the regulator and thermostat.
• Compact: One device serves up to four independent heating circuits. One power output is available for each heating circuit; this can take a load of up to 10 A.
• Cost effective: The ability to dispense with a lot of individual devices and simplify the wiring brings considerable potential savings.

DC/DC Converters

On vehicles with 110 V on-board voltage it’s often necessary to provide a simple DC 24 V supply voltage for small consumers. With a wide range of suitable DC/DC converters, LÜTZE can supply numerous tailored solutions from 6-50 W.
So for example, our smallest version supplies DC 24 V, 6 W in a compact design for top hat rail mounting.

Dimmer Switch

Special tasks require tailored solutions. If our extensive range does not offer the right solution for your task, just talk to us. Based on our extensive experience in electronics for rail vehicles, we can develop the right component for your project too. An example is the dimmer switch 716317, which, in an underground train, ensures that the interior lighting is switched on and off automatically according to the presence of daylight.
