UV MODULE/BALLAST WIRING HARN

An electrical ballast is a device that limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases. If such a device were connected to a constant-voltage power supply, it would draw an increasing amount of current until it is destroyed or causes the power supply to fail. To prevent this, a ballast provides a positive resistance or reactance that limits the current. The ballast provides for the proper operation of the negative-resistance device by limiting current. Series resistors are used as ballasts to control the current through LEDs.

In foodservice equipment, a module is one sub-component (or "part") of a larger more complex device that may be the fully assembled piece of equipment itself. A module may refer to a variety of replacement parts including relay modules, ignition modules, communications modules, heater modules and others.
