N & TN Series Single Phase Dual Conversion On Line

  • Single Phase Input
  • Single or Split Phase Output
  • Dual Conversion On Line UPS
  • Industrial
  • Commercial
  • Critical Loads

Always On™’s N and TN Series are dual conversion true on‐line UPS systems which provide the attached loads with isolation from the utility or generator supply and are designed for all critical applications. These critical loads are supplied power from the inverter, which is fed by the batteries. The N Series systems are available from 700VA to 3kVA, and the TN Series are available from 6kVA-20kVA with single phase input and single phase or split phase output with multiple voltage configuration.

Among other applications, the N and TN11 Series can be applied to LAN file servers, personal computers, networks and workstations, Automatic Teller Machines, telecommunications, laboratory and medical equipment, test equipment, POS equipment, robotics, PLC’s, security and emergency systems and military & government applications.

Advanced Features

Features include utility input power factor correction, self‐diagnosis, an LCD display, a static bypass, smart power source monitoring and battery management, lightning, noise and surge protection, spike and transient protection, cold start/auto restart, a user selectable frequency, a generator mode and intelligent communications interface. SNMP and AS‐400 adapters are available for network management. User replaceable batteries, emergency power off control, an isolation transformer and maintenance bypass switches are standard on the TN11 Series.

Complete Protection

The N and TN11 Series UPS’s are designed with comprehensive spike, transient and surge protection, which prevents destructive hardware damage and extends system life. The high end EMI/RFI filtering design prevents electrical Common and Normal Mode noise from affecting computer operation, data or files, including when the UPS is in Bypass Mode.

Operating Voltages And Frequencies

The N and TN11 Series UPS’s are designed to function at wide voltage and frequency variations. This wide input range makes the systems ideal for generator and problematic area applications. Also available is a frequency converter option allowing the user to select the output frequency at 50 or 60Hz.

Self‐Diagnosis And Information Indicators

Each N and TN11 Series UPS is equipped with a microprocessor that performs a self‐diagnosis once a month to ensure continuous runtime. The microprocessor is able to identify failures, display the failure on the LCD display and send audio and visual alarms (off site monitoring).

Cold Start

This feature allows the N and TN11 Series UPS’s to be powered up when the utility is not present.

Auto Restart

This user selectable feature allows the UPS to restart automatically when utility becomes available, provided it has been shutdown due to an extended blackout.

Smart Power Source Monitoring And Battery Management

Via microprocessor‐based electronics, the N and TN11 Series UPS’s produce a strict true sine wave output regardless of the input. It also controls the on‐battery and low battery shutdown, which prevents full discharge, thereby extending the battery performance and battery life.

High Efficiency Mode

The high efficiency function adds cost effectiveness, maximizes efficiency and reduces power consumption. Alternating between bypass and on‐line modes is achieved automatically and in accordance with the conditions of the AC supply power. On‐line mode may be used during times of intermittent power, and bypass mode when the utility is within user selectable parameters in order to obtain greatest efficiency. Irregularities can be detected in less than a second, and on‐line mode reactivated immediately.

Intelligent Communication Interface

Each N and TN11 Series UPS is equipped with a RS232 and dry contact interface port, for which we provide various powerful management software programs. For the more complex network environment, we support Simple Network Management Protocol (SNMP), AS400 relay contacts and other options, by adding a plug‐in module to the accessibility slot.

Remote Shutdown and Emergency Stop

Features include remote shutdown via communication port, emergency stop via contacts. An optional push button control is available.

Optional Extended Runtimes

To meet your back‐up time requirements, we offer increased back‐up time by simply adding additional hot pluggable battery cabinet(s).

Optional USB

Available at time of order.

Optional External Bypass

Allows the UPS to be completely shut down or even removed so that maintenance can be performed safely without any downtime. Available at time of order.

Single Phase Input and Output

Specifications are subject to change without notice to reflect upgrades and improvement in technology. Industrial containers are available (NEMA 12, NEMA 4, etc); consult manufacturer. External wrap‐around bypass modules are available for all models, permitting UPS maintenance without power interruption to the load.

Backup Times (Battery Banks)

To meet your back‐up time requirements, we offer increased back‐up time by simply adding additional battery cabinets. To determine the battery bank part number, locate the UPS model number and additional runtime you want to add from the tables below. For alternate runtime or runtime calculations, please contact our factory.

Standard 5‐year pro rated warranty with 1‐year replacement. Extended warranties available.

Single Phase Input and Output (2 or 3 Wire)

Other voltages and configurations are available. For order codes, consult Always On. An external wrap‐around bypass module is available for all models, permitting UPS maintenance without power interruption to the load. Industrial containers are available (NEMA 12, NEMA 4, etc); consult Always On
