UPS Un-Interruptible power supply
- Normally achieved with a battery backup.
- see
The main focus here is to look at requirements for a UPS at a small remote branch or remote site.
Surge protection
Kinetic UPS
euro-diesel kinetic ups + gen set.
Requirements / Ideal for remote unit's
- Critical
- Remotely managed through network SNMP and possibly WEB
Status & Events, on-line, off-line, battery problems (SNMP and TRAPS)
- Multiple input's
- Escom power from grid
- Solar from panels
- Wind ?
- Generator set - Autostart
- Tolerant of harsh environment - 65C and vibrations.
- 220V output or 48V. (Cisco needs 48v Regulated)
- Remotely managed through network SNMP and possibly WEB
- Preferred
- External battery's
- Either modular, or capable of adding external lead-acid battery's
- Power flow
- Watt's in and out on each input and output.
- Battery management
- Protection against damage due to full discharge
- Measurement and reporting on quality/status/life of battery unit
- External battery's
- Nice to have
- Remote power control, or scheduled control
- Capable of switching off certain outlets (4-6 Outlets)
- Environmental
- Temperature etc. that could reduce battery life.
- Capable of operating at high temperatures e.g. 65C
- Reporting and historical data
- Remote power control, or scheduled control
Equipment power requirements
- 16w - Cisco 3000 Industrial Ethernet switch - 15Watt
- 50w - Motorola PTP300
- 12w - Cisco 350 AP
- ??w - Rectifier + Management
Total: 16w + 50w x 4 + 12w x 2 = 240w ==> 5A@48v
Home Made UPS
Aviosys power monitoring unit with network connection + relay's
South African Company's
- GSM-Tronix
- Meisner
