Power Management System
General Details
Power Management System is highly integrated, software driven system for control and monitor of AC power supply at cell base stations of telecom towers.PMS performs stabilizers, AMF function and also act as a single point control and monitoring facility for mains, generator and site alarms.
Product Highlights
- Total power management of cell sites.
- Regulates mains supply and AMF functionality inbuilt.
- Optimum use of cell site battery back-up and generator running time.
- Wide voltage band accepting range from 240V to 485V.
- Response time <10 m.Sec.
- System efficiency >97%.
- Lighting and surge protection.
- DG parameters measurement like DG battery and DG alarms.
- DG fuel saver logic.
- PC interface to configure, alarm and data capture.
Technical Info
| Capacity | The system is suitable for 7.5KVA, 10KVA, 12.5KVA,15 KVA,25 KVA,37.5KVA, 40.KVA, 63KVA. |
| Control logic | Control logic should work on 3 phase input. During the absence of mains i.e. all phases are Unhealthy/fail, it switches OFF the mains and run the DG as per the DG logic if controller selection is 3P-3P. In case of a 2P healthy condition, the system will run on the available 2 phases. |
| Voltage range | Voltage range: 240V – 485V ( Phase to Phase) |
| IP protection | IP 21 for Indoor application IP54 for outdoor application |
| Time | Real-time & Date programmable |
| Event logs | Last 500 events |
| Voltage protection at the incoming power input | 1) 3PH-3PH A) High Voltage Disconnect (HVD) 493V B) Low Voltage Disconnect (LVD) 265V 2) P-N is selected A) High Voltage Disconnect (HVD) 285V B) Low Voltage Disconnect (LVD) 165V |
| Protection on DG1 | Provided – When the AMF is selected in manual mode the DG safety should work. |
| Potential Free Dry Contacts | Alarms can be extended to NOC / TOC through changeover contact ( both ‘NO’, ‘NC’ ) |
