ESU 53900 Decoder Tester. Brand new in original packaging. We're an authorized ESU dealer, feel free to get in touch if you don't see what you're looking for we're happy to order it!


Perhaps you are familiar with this scenario: there is a digital decoder sitting on your workbench and you want to test it prior to a perhaps complex installation. But how to do this?

The Profi Decoder tester makes it easy for you: simply connect the tester to your command station or the LokProgrammer. It enables you to test any decoder without exposing it to any external factors caused by the locomotive that may influence its performance.
Features

In order to make things as easy as possible for you, the Profi Decoder Tester is equipped with some useful features. It has all commonly used interface sockets for connecting a decoder for the smaller scale models:

Besides a 6-pole NEM 651 socket and the 8-pole NEM 652 socket, it also has an 21MTC interface as per NEM 660, a PluX22 socket as well as a Next18 interface. Please note it does not have a 9pin JST plug but that can be easily overcome with an 8pin adapter harness (not included).

Decoders without any interface can be contacted with individual terminals.

A quality coreless motor with flywheel serves in conjunction with LEDs indicating the direction for checking the motor output: Thus it is quite easy to check on the low speed performance and the even speed of the decoder. An LED monitor informs you about the functioning of the headlights and back-up lights as well as the function outputs AUX1 through AUX6.

For testing LokSound decoders we have integrated a 20 mm speaker. You may choose if the integral speaker should be switched off or if it should have 100 Ohm respectively 16 Ohm – thus the Decoder Tester is perfectly suitable for any ESU decoder generation!

Two SUSI plugs facilitate the direct test of optional SUSI modules as well as the connection to another circuit board.

The electrical connection to either the command station or the LokProgrammer is facilitated by a removable, 2-pole terminal block (same system as used on the LokProgrammer and the ECoS) or via two solder points (which also accept alligator clips nicely).
