We, Power Energy Conservation offer our clients various energy conservation related solutions such as Energy Monitoring System, Energy Accounting System and Energy Management System.
 

• Our energy monitoring system is ideal for monitoring the consumption online. It is connected in the network wherein it collected the data at fixed interval. The reports regarding power consumption is generated periodically which is send to users through email.
• Energy accounting system which we offer to clients is more effective than the monitoring system. Our energy accounting system accounts the consumption with respect to a process like energy consumption per unit production. It is also ideal for monitoring efficiency and for verifying the process.
• Our energy management system monitors energy meters, temperature, pressures and lux meters as well as controls processes such as switching on lights when lux level is at lower threshold and switch off on reaching upper threshold. It also helps in cutoff air conditioning once target temperature is reached.

PEC  custom designs the Street light controllers. We have following type of street light controllers.
 
1-      Digital Clock based street light Control system: One may set the “On time” and “off time”. The switching of steet lights shall be repeated every day. Another option may be designed for switching ON/ OFF the alternate lights at designated time to save energy without compromising the requirements.
 
2-      “Sun rise / Sun set” based Street light Control System :
 
a.      Uses digital clock based timer.
b.       Timer has memory to store the sun set and sun rise data for complete year.
c.       The timer has RS-485 communication port and uses MODBUS RTU protocol. The software with RS-485 to USB converter  can be used for communication with timer.
d.      One may feed the data for complete year which may be repeated every year.
e.       At any point of time the data may be modified by the user.
f.       Optionally one may install the wireless communication device for communicating with the “ Street light control systems”
g.      Optionally Energy meter with RS-485 port may be installed and data for energy usage may be collected on line.
 
One may think of any other usage of this system . we shall try to customize the same.
 
3-      Light / Lux based control for switching the street lights:
Light sensor is used for switching the lights. It is very important to
a-      place the light sensor in right direction.
b-      It should get the sun light directly without any hindrance.
c-      No auxiliary light should fall on it.
d-     Routine cleaning of sensor is must.
 
4-      Street light control with Dimming for energy saving :  The idea behind the control strategy is that during the late night till morning the traffic is low and hence it is possible to reduce the lux levels. The diming makes the lights uniform throughout the street and saves valuable energy. The saving may range from 20% to 35% depending on the control strategy and choice of lamps / fittings.                              We offer dimmable ballast based FTL (fluorescent tube) lights. The ballasts can dim the lights from 100%  to 10% of power level. Dimming may be automated with digital timer  based controls.
