The Sargent EC155/EC50 kit is an all-in-one 'plug-and-play' electrical system for campervans, motorhomes, caravans and other leisure vehicles. These complete kits are very popular amongst professional and DIY converters alike for their integrated design and ease of installation. All the major components you need for your installation are supplied, including fully built wiring harnesses for the 230V AC and 12V DC parts of the system.
EC155 Power Supply Unit
The EC155 safely manages all your 12V and 230V distribution in one compact enclosure and contains a 150W, fixed voltage (13.8V) charger for re-charging wet lead-acid leisure batteries* from a mains hook-up and a split charging function for re-charging wet lead-acid leisure batteries from the vehicle alternator (Euro 4 & earlier vehicles ✝).
The 230V distribution system comprises 3 MCBs & an RCD to supply power to 3-pin sockets, heater, water heater etc. as well as the integrated 12V battery charger. The 150W charger can supply up to 12A and is capable of both charging your leisure battery and powering your 12V systems at the same time (the 12A output is shared, e.g. 3A used for powering 12V circuits leaves 9A for battery charging). The 12V distribution system comprises 12 circuits protected with automotive blade (ATO) fuses for powering internal lights, fridge, water pump, hob ignition, ventilation fan, 12V sockets, heater fan etc. as well as protecting the connection to the 12V charger.
EC50 Control Panel
The EC50 has a number of buttons with indicator lamps to control functions such as Main 12V power ON/OFF, Pump(s) ON/OFF, Aux power ON/OFF, Battery selection (starter/leisure) and features a 5-level LED indicator to show battery voltage level. The coloured surround used on the EC50 Control Panel is a grey 2-way outer frame from the CBE modular switch & socket system. It can be swapped for any colour 2-way outer frame so you can match it with the rest of your CBE system if required.

✝ IMPORTANT NOTE:
This kit is intended for installation in vehicles that have a standard alternator (Euro 4 spec engine or earlier) and the split charging feature will not work effectively in vehicles with a Euro 5 or 6 spec engine. If you wish to fit this kit in a vehicle with a Euro 5 or 6 spec engine then you will need to disable the split charging feature in the kit and fit a separate battery-to-battery (DC-DC) charger to charge your leisure battery from your alternator. Details of how to do this can be found in the installation instructions, downloadable from the Manuals & Guides tab above. Please contact Sargent directly if you require detailed technical support in relation to this.
Sargent now produces its own DX320 20A DC-DC charger for this purpose which can be found here (other DC-DC chargers can be used).
