1600EP Series Instruction Manual

Product Description

An uninterruptible power system is a system that is installed between the commercial power and the load equipment. The UPS provides steady AC output power during commercial power short-term blackouts or brownouts. This power is provided for a long enough time so that the load can be shut down in an orderly fashion. This prevents loss of data and possible damage to both hardware and software.

During normal operation, the UPS uses commercial AC power. It absorbes all of the high voltage spikes and transients caused by switching and faults, and all of the common-mode and normal mode noise which is associated with commercialAC power. The UPS converts it all to flat DC power. From this power, the UPS charges its batteries and generates its own extremely high quality AC waveform output. The result of this process is maximum power conditioning and regulation.

If theAC power supplied to the UPS drops below a specified voltage level, the unit’s batteries automatically begin supplying power instead of receiving it. This insures that the loads connected to the UPS continue to receive power with no interruption. When AC input power becomes available again, operation returns to normal. The unit’s batteries begin to recharge so they will be ready for the next power interruption.

Application and Use

Toshiba 1600EP Series of on-line uninterruptible power system (UPS) provides continuous computergrade AC power in a compact, high performance, and energy efficient unit. The UPS unit assures safe and reliable operation of critical office equipment. This can range from word processors and personal computers to mini-computers and local area networks. All units feature an audible alarm which sounds if the battery voltage drops below a specified minimum during use. This is an additional aid to help in retaining the valuable office data banks. All units allow for computer interfacing.

Output Rating

Toshiba 1600EP Series (208/240V) offers UPS models with the following capacities:

MODEL	Output Capacity @ 240 V	Output kW @ .85PF 240 V
UE3G2L036C61TRoHS*	3.6 kVA	3.1 kW
UE3G2L036C61T	3.6 kVA	3.1 kW
UE3G2L060C61T	6 kVA	5.1 kW
UE3G2L080C61T	8 kVA	6.8 kW
UE3G2L100C61T	10 kVA	8.5 kW
UE3G2L140C61T	14 kVA	11.9 kW
UE3G2L180C61T	18 kVA	15.3 kW
UE3G2L220C61T	22 kVA	18.7 kW

* UE3G2L036C61TRoHS is RoHS compliant with the batteries being exempt from the directive.

Power Backup

When an electrical power failure occurs, the UPS’s internal batteries automatically supply back-up power to the load without interruption. For example, when used to support a computer, the UPS back-up assures enough additional time to complete the activity and store the data. This allows an orderly shutdown after a power failure has occurred.

Power Conditioning

When commercial power is present, the UPS supplies conditioned power to the load while maintaining its batteries in a charged condition. The UPS protects against the normal, everyday problems associated with heavy use of raw commercial power, including power sags, surges, signal interference, and spikes. This protection keeps power-line problems from reaching your load, where they can cause equipment to operate erratically, or damage software and hardware.
