MURRELEKTRONIK, represented in Australia by Sick , has released compact the MTL range of 25VA-400VA transformers. They have an LED indicator on the input side which signals the presence of the primary voltage.
The multiple winding on the primary side means that each transformer can be used for both 230V ac and 400V ac. Additional terminal blocks also allow voltage adaptations of ±15V ac to be made.
The removable combination foot plate can be screw-mounted in the normal way, snapped on or support rail-mounted. The benefits of the mounting plate are particularly evident during assembly. The lightweight mounting plate can be removed from the housing and attached separately. The transformer is then simply snapped on again. This type of assembly system is available for the entire product line.
The transformer is supplied with two equivalent output voltages as standard. These outputs can be connected in parallel or in series via plug links within the transformer in order to obtain the required secondary voltage or output power. PE and 0V can be bridged in the same way. The plug link positions are also clearly evident with the cover closed, which provides information about the current switching status of the outputs.
As well as the transformers, power supply units with transformers up to 10A are also available with the same design.
