Electrical Distribution

Eaton PLP-25 Parking Lot Control panel is used to control the amount of power provided to Block Heater receptacles, reducing electricity used by as much as 50%. This is done through the use of a remote temperature sensor. As the outside temperature increases, the system is designed to reduce the duration of ON-time, thereby reducing power consumption. In addition to receptacle control, 2 zones in each panel may be designated as lighting zones and will operate based on photo sensor input or timed of day switching.

User Interface
Pow-R-Command PLP-25 is the optimum parking lot control system offered by Eaton's electrical sector. The Pow-R-Command PLP25 system, comes with a standard HMi touch screen graphical interface for programming and set-up. The Pow-R-Command PRC-PLP25 controller can control up to 6 preconfigured zones. The heart of the Parking Lot Control Panel is the zoning board integral to the panelboard. The controller provides the ability to group individual smart breakers into zones.

Block Heater Control To Reduce Power Consumption
Each zone will operate automatically to vary the amount of energy delivered to the parking lot block heater outlets, based on outside temperature. The cycle time duration (duty Cycle) is variable between 4 and 60 minutes and may be set by the user during initial set-up of the system. The temperature control schedule will be based on a stepped system with fixed percentage ON-time with variable temperature input. Thermocouple input will be divided into 5 temperature ranges set by program but may be altered by the end user via the HMi touchscreen panel. The total duty cycle will be set at 20 minutes. Also, whenever possible, the PLP25 program will attempt to level the demand loading by minimizing the number of zones that are energized at any given moment.

Additional Parking Lot Lighting Zones
Every Pow-R-Comman PLP-25 panel comes with 2 of 6 breaker zones that can be programmed for either Block Heater receptacle control or Parking lot Lighting. If Zone 6 (or zones 5 and 6) are set up as lighting zones then their operation will be determined by either a photocell input or a timed ON/OFF schedule. A maximum of 2 ON/OFF cycles are included to allow parking lot lights to be turned OFF during late evening hours and on for early morning.

Enclosures
Pow-R-Command PLP-25 is designed to integrate within standard 20 Inch lighting and appliances panelboards. These may be used as stand-alone panels or integrated into Eaton’s Integrated Facilities System (IFS) switchboards.

Smart Breakers Technology
Eaton's electrical business, a market leader in electrical distribution and control, offers an innovation Smart Breaker technology. Smart Breakers offer the function of a low voltage remote control switching device coupled with the thermal magnetic over current protection of a standard branch circuit breaker in one compact design. Smart breakers are designed to be mounted in all standard CH panelboards.
