·The advantages of EPS compared with generating units
|
Indicators |
EPS Three-phase Emergency Power Supply |
Standby Generators |
|
Starting time |
≤0.1s |
5 to 30s |
|
Maintenance |
Simple maintainance, and unattended automatic operation and computer monitoring can be realized |
Need someone to look after and need regular maintenance |
|
Power status |
Stable supply voltage, stable frequency, good waveform, no interference, high efficiency |
Instable voltage and frequency, low efficiency |
|
Overload and Protection |
Strong overload capability and protection function, the rate of power capacity and load power of this power supply is low, generally1:1, the investment can be reduced |
Weak overload capability, general protection fuction, the rate of power capacity and load power of standby generator is high, generally at least1:1.5 times, the investment will be increased |
|
Price and operating costs |
Basically no follow-up operation into a one-time costs, the battery can be recycled anti-electrical charge for 300-500 times |
The purchase cost of the generator is low, but the cost of ancillary facilities is high, and there are a lot of follow-up operating costs |
|
Environmental |
No exhaust smoke, no noise, no vibration, pollution-free |
With sulfur dioxide emissions, smoke, large noise, with vibration and oil depot fire safety requirements |
