Difference Between EPS and UPS
| Item | EPS(three phases emergency power supply) | UPS (uninterruptible power supply) |
| Electricity saving | It operates in sleep mode when the electric fence is normal and electricity consume is less than 0.1%. When the electric fence stops, the EPS starts working and its efficiency is 92% or above. | It operates in working mode even if the electric fence is normal. The efficiency is in the range of 85-90%, and about 10-15% electrical energy is consumed |
| Noise | When in normal electrical net work power supply, it operates in sleep mode with no noise. When in working state, the noise is less than 50dB. | The UPS working noise is between 45dB and 55dB. |
| Service life | It only starts to work when the AC input is unavailable. So the service life is longer and can be used at least 20 years. | UPS will work uninterruptedly as the machine operates. Its service life is shorter is in the range of 5-8 years. |
| Load compatibility | Especially suitable for motors or others with inductive load or all kind of mixed electricity load. | Only suitable for the capacitive load and the resistance load (computer load). |
