Pow-R-Command Lighting and Load Control
Pow-R-Command PLP-25 Parking Lot Control Panel
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.
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.
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.
