The Trojan UV Max 650713-003 is replacement power supply kit (also called a controller) that is used to replace the power supply of a Trojan UV Max system. The 650713-003 is the newest version of the company's line of A, B4, C4, D4/Plus, E4/Plus, and F4/Plus controllers and is used for the Trojan UV Max F4 system. 
The 650713-003 controller operates at 100-240V and weighs at 1.4 kilograms. The Trojan UV Max 650713-003 plugs into a wall outlet and acts as a transformer - taking the native voltage and amperage and converting it to the proper voltage and amperage for the UV lamp.  It also provides valuable information to the UV system operator in the way of a digital readout, making it easy for you to determine UV purification levels and the need to replace the controller again.
