Lennox Y0393
UVC-24V POWER SUPPLY/BALLAST
SKU: LENY0393
Condition: NEW
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.
Power supplies in restaurant equipment are used to provide electrical energy to operate appliances such as:
- Commercial ovens
- Refrigerators and freezers
- Dishwashers Coffee makers
- Grills and fryers
- Food warming equipment
- Blenders and mixers
The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power.
Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible power supply).
