9. POWER SAVER PANEL

10. Features of Power Saver Panel
Power saving is above 20% in lighting
No load currents is very low below 1% of the rated output current
On/off control can be achieved by time, dusk –dawn control, PLC& manual mode
When used in manual mode all the control circuit is been bypassed directly, used in case of emergency
Compact in size, box can be custom designed as per the requirement of the customer
Programmable logic controller can be used for sequential, on/off for lights
Easy to install with existing control unit and cabling
Payback period is 8 to 12 months based on site conditions and usage
Low maintenance, No moving parts, easy to service
