IPSS Intelligent Lighting Energy Saver
5 Advantages
1． Safety Guarantee
With seamless auto-bypass in case of any system failure; safe and no worry about lighting blackouts
2． Easy To Operate
Wide range of application; Easy to operate
3． Innovative Technology
Output power is accurately controlled by digital technology, ensuring a longer lifespan of lightings
4． Stable Performance
Constant power output ensures stable voltage output, satisfying both energy-saving and illumination requirement
5． Energy Efficiency
The combination of Electrical & Electronic technology and Electromagnetic technology, which makes use of digital output technology, enables an energy saving rate up to 45% maximum.
Technical Principle
COPOWCO IPSS series of Intelligent Lighting Energy-saver applies our patented technology of “Series controllable voltage stabilization” & “Intelligent stepless on-load power control”. The combination of Electrical & Electronic technology and Electromagnetic technology enables us to achieve an intelligent, uninterrupted, stepless and steady power control.
According to “P=UI”, the device changes the power of the lighting indirectly by regulating the output voltage, in the premise of illumination requirement. It starts the lamps with their startup voltage to warm up, then adjusts the output voltage steplessly and seamlessly, thus reduces the power of lighting in directly, and achieves energy-saving.
Schematic Diagram
1. Increaseable & decreaseable output voltage; 1/10000V voltage adjusting pace ensures a stepless control and effectively protests the lamps, and in return for this, longer lifespan of the lamps
2. Excellent voltage stabilization; an output voltage accuracy of ±0.1% brings about stable running of the lighting and guarantees the maximization of energy-saving
3. Up to 12 adjustable energy-saving time intervals; brings about a reasonable and scientific 45% energy-saving rate
4. Auto-Bypass system for directly linking the lighting with the mains in case of a system failure makes you sit back and release from the concern of lighting blackout
Wireless Remote-control System
COPOWCO provides you a perfect package solution of remote-control and theft prevention system, saving your manpower and material resources by using the latest GSM/CDMA even G3 network communication technology
Energy Saving Analysis
IPSS Series provides a remarkable power saving opportunity and an attractive ROI (return on investment). The following case study demonstrates how a public lighting system can benefit financially from an IPSS retrofit.
Background information for the highway: 100 sets of high-pressure sodium lamps; 400W per lamp; main voltage is stabilized to 220V.
Lighting hours per year: 365d ×12h/d=4380h
Lighting hours under energy saving mode, assuming 8 hours per day:
365d × 8h/d=2,920h
Charge per kWh: US$0.10
Actual service life of high-pressure sodium lamp under normal use: 4,000 hours (normally between 3,000 and 5,000 hours)
Cost of labor and material for replacement of one high-pressure sodium lamp at 400W: US$50
Average energy saving rate for high-pressure sodium lamp: 35%.
Direct Savings:
Total lighting circuit demand: 40kW
Electricity consumption per day: 480kWh
Electricity cost per day: US$48.00
Annual saving in electricity charge:
40kW × 8h × US$ 0.1/kWh × 35% × 365d=US$4,088.00
Indirect Saving:
Before using IPSS, average service life of lighting fixture is 4,000 hours,
i.e. number of replacement : 1.1 per year
After using IPSS, average service life of lighting fixture is 12,000 hours,
i.e. number of replacement : 0.4 per year
Annual saving in replacement:
100 sets × US$50.00 × (1.1-0.4) = US$3500.00
Conclusion: Total annual saving for a 40kW highway section can reach US$7,588.00. If the mains voltage fluctuates around 230V frequently, the saving rate for the lamps can jump to 45% and the total annual saving rises to US$8,756.00!
