Description
With ever greater demands being made on the IT manager, a reliable and robust power supply is crucial in today’s computer dependant world. Borri UK are proud to introduce the B300 On-Line UPS to facilitate this need. In the past On-Line technology has struggled against low price Line-Interactive and Off-Line topologies offered by some of the world’s biggest brands, however with the help of modern production techniques On-Line technology has come of age.
UPS Management Software
The UPS management software is installed on the server or workstation and connected to each UPS via the serial or USB port. Power failure, power restored, battery failure or eight other events can be detected and the user informed. A shutdown will be initiated when the batteries are exhausted or a technical problem occurs with the UPS. The UPS management software disconnects network connections, logs out users and closes open applications (subject to app/os support) before shutting down the operating system itself.
- Extensive log files
- Scheduled battery and inverter testing
- Scheduled system shutdown/re-start
- User-customisable commands and messages
- Multiple UPS control from a single computer
- Remote Console Command module for remote multiple server shutdown
- Internal SNMP sub-agent for integration into existing NMS (e.g. HP OpenView, CA Unicenter)
Simple Network Management Protocol (SNMP)
The B300, SNMP agent can be internally installed in the ‘intelligent’ slot. Initial configuration is carried out by serial comms using any suitable terminal application (e.g. Hyperterminal for Windows). The embedded HTTP server presents an HTML interface to the network which can be accessed from any web browser. All system parameters can be configured from here, including scheduled shutdown. A Java applet provides full monitoring in real time along with comprehensive event and history logs.

Online Double Conversion
An uninterruptible power supply using true online double conversion technology provides the highest level of power protection available. The UPS converts the 230V input AC mains supply to DC power which is then used to charge the battery. The DC current flow is then fed through an inverter stage which reconstructs the 230V AC mains output. Because the AC output is completely regenerated, it will be completely free from any mains-borne interference such as spikes and voltage variations.
The output voltage and frequency is controlled precisely, thus ensuring a clean and stable sinewave power output. Online UPS are able to withstand large fluctuations on the input voltage before transferring to battery power (typically 276V-184V) thus eliminating unnecessary battery discharges. Upon mains failure, transfer to battery power is seamless – no break. Online UPS also have various failsafe and self-diagnostic features that will instantly transfer the load onto mains power if there is a failure within the UPS hardware, or if the UPS is overloaded.
Advantages:
- Continuous & total power conditioning
- Failsafe/overload protection with static bypass facility
- No break on mains failure
- Wide input voltage tolerance
Disadvantages:
- Due to the advanced technology used in online conversion, the costs are usually more than other types of UPS technology
