T3R (NSR Series)

1kVA - 3kVA

With ever greater demands being made on valuable floor space, many IT managers are moving towards computer rack solutions rather than conventional floor standing options offered in the past. The same philosophy has affected the UPS industry with many UPS now being located with the computer inside the rack cabinet. On-Line UPS have historically been handicapped in this particular market sector, essentially for two reasons, size and price. Most IT managers have dealt with this problem by moving to Line-Interactive or Off-Line topologies. As these technologies have fewer fail safe features and for the most part work only when a problem occurs. With the introduction of the T3R series these past limitations are no longer valid.

The T3R is a physically small On-Line double conversion UPS but retains all the features normally associated with On-line technology, but what is On-Line double conversion technology and why does it matter? Simply put, “double-conversion” is where the mains supply is rectified to a clean DC voltage and rebuilt into a very clean and regulated AC voltage at all times your critical load runs from this clean no break supply. Line-Interactive and Off-Line UPS are single conversion, put in its crudest form, your computer runs on semi regulated mains and will always suffer a small break in supply whist the UPS moves from mains mode to battery mode in a mains fail situation. The T3R offers a competitive price, even against the more basic technologies, but unlike these technologies you will get as standard an LCD screen, RS232, USB port, battery extension options, battery monitoring, no-break supply, static switch, wide voltage input without using batteries, optional software, comms slot for SNMP, Relays or Optocoupler.

SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)

The T3R SNMP external agent can be located up to 5 metres away from the UPS. 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 sophisticated Java applet provides full monitoring in real time, along with comprehensive event and history logs.

UPS MANAGEMENT SOFTWARE

The UPS management software is installed on a server or workstation connected to each UPS via the serial port. Power failure, power restored, battery failure or eight events will 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.
