We ship worldwide. At checkout you can choose from low cost airmail options and express courier services like DHL or FedEx.

Within the UK we normally dispatch using Royal Mail or DHL. You choose the level of service at checkout.

VAT sales tax (20%) is included in the price displayed on the website. This tax applies to UK customers and EU customers. It will continue to apply to customers in the 27 EU member states from 1 January 2021. This is because we are located in Northern Ireland. The Northern Ireland Protocol, agreed by the EU to facilitate cross border trade with the Irish Republic after Brexit, also applies to the rest of the EU.  We continue to charge the UK rate of vat to customers in the 27 EU member states and there is no further tax to pay upon delivery. We can continue to zero rate the vat for EU business customers who enter their vat number at checkout. 

Customers outside the EU do not pay vat and the tax will be removed at checkout. Local import taxes may apply - check with your local authority.

Currency. All products are priced in Pound Sterling (GBP, £). Using the "Currency" tab you can change the displayed currency to either Euro (EUR, €) or US Dollar (USD, $). This is an indicative exchange rate, automatically updated daily and is based upon the prevailing bank rate. The price you see may be displayed in USD or EUR but payment processing will be conducted in GBP. This means that your card issuer will apply their usual exchange rate, which is likely to be different from our indicative rate. 

This module can operate completely stand alone and does not require any form of external device such as an EFIS system or laptop computer for configuration - however, using an MGL EFIS does extend the configurability to detail level.

Connected EFIS systems can show breaker states, control breakers and reset faulted breakers. Alarms can be issued on a faulted breaker. The EFIS can also show the individual current flowing through each breaker.

Up to 8 of these modules may be used in a single, connected system giving up to 64 usable breakers.

Advanced functionality includes landing light "wigwag” (alternate flashing of landing lights) as well as strobe implementation able to drive high brightness LED lamps directly.

The ECB implements a highly robust and fault tolerant design allowing full use of latest "high side” semiconductor switches with built in protection circuits and devices making them effectively indestructible.

Owing to low cost the ECB for the first time presents a viable alternative to old fashioned mechanical breakers while greatly enhancing reliability of the aircraft electrical system and allowing decentralised power distribution. It is no longer required to bring high current wiring to the panel


If required, download the ECB interface application for Windows. This connects via an RS232 port (USB to RS232 dongles are OK) to the RS232 port of the ECB module (or multiple modules if you have them daisy chained).

This can be used to configure the programmable profile if you are not going to use an EFIS system. This is also a handy tool to verify operation in a "stand- alone” system.

Download the ECB interface from This Link

You will be downloading the file MGLECB.exe. Copy this file into a folder location of your choice and run the file from that location. Using the COM port setup, choose the COM port you will be using to interface to the ECB. Once connected you should see an image similar to the one below.

  EU Customers - NO TAX or CHARGES on delivery 

We are located in Northern Ireland and will continue to export under EU Customs Rules (unlike companies in the rest of the UK). Nothing changes because of Brexit. You continue to pay the vat inclusive prices on our website and you will not pay any tax or tariffs upon delivery. Businesses in the EU can enter their vat number at checkout and we will zero rate the sale. 

And of course, there is no change for our customers throughout the United Kingdom.
