Utilization of device technologies reduces equipment mass

Utilization of 3-level modules with RB-IGBTs*1 and conventional IGBTs in one package to simplify the circuit configuration as well as miniaturization of filters have reduced the mass of the equipment by about 40% compared with our conventional models.

*1 RB-IGBT; Reverse Blocking-Insulated Gate Bipolar Transistor (or reverse blocking IGBT)

High efficiency

Our new power conversion technology (featuring new three-level conversion circuits) reduces the switching losses of the IGBT elements. Additionally, reducing the harmonic components in the PWM waveform output from the inverter by half compared with our conventional products reduces filter losses and achieves a best-in-class equipment efficiency of 95%*2.

*2 Indicates the maximum efficiency of the equipment, and is not a guaranteed value.

The above table represents approximate calculation values for continuous operation at a 100% load for one year.

Simple human-machine interface

An LCD touch panel with character display enables the operation status of the equipment to be checked at a glance and operation guidance, event history and various measurements to be displayed.

Wide range of input and output voltages

The rated input and output voltage can be set within a range of 200 to 220 V. This wide range has been achieved by an addition of 220 V to the conventional rated input and output voltages of 200 V and 210 V.
In addition, the input voltage tolerance range is −30% to +10% of the rated voltage and the output voltage is kept constant without requiring battery operation even in power transmission environments that experience large voltage fluctuations. (Note that this performance is dependent upon the load conditions.)

Enhanced network system functions (option)

The installation of an optional Web/SNMP card makes it possible to monitor the status of the equipment using a web browser, receive event notifications by e-mail, perform remote maintenance, shut down multiple servers, and monitor the status using SNMP manager software (JEMA-MIB compatible).

Built-in maintenance bypass circuit (option)

A maintenance bypass circuit built into the UPS is available as an option. This built-in maintenance bypass circuit enables higher maintainability with only the UPS equipment.

Batteries (service life and backup time )

Battery types

A UPS uses battery power when the power being supplied by the grid fails. A UPS is normally set to cover a power outage of about 10 minutes. The battery capacity needs to be increased for coverage of longer power outages.
However, covering long power outages with batteries is not economical. When it is necessary to be able to provide backup power for outages of one hour or more, generally an emergency in-house power generator is installed on the input side.
There are various types of batteries, but UPS systems commonly use rapid-discharge lead-acid batteries mainly for economic reasons. Various types of rapid-discharge lead-acid storage batteries are being manufactured.
The following table presents an overview and comparison of typical batteries for reference.

Valve-regulated lead-acid (VRLA) storage battery Alkaline storage battery

Remarks Conventionally used in large capacity UPS systems Life-cycle cost benefit More advantageous than MSE type in terms of size and price (monoblock type enables additional space-savings) Standard use in small and medium capacity UPS systems High price, used for special applications

* Expected service life at ambient temperature: 25℃, number of discharges: several, and discharges of 0.1 to 0.16C 10 A.

* The Fire Prevention Ordinance is applicable to batteries with capacities of 4,800 Ah/cell or more. For such batteries, notification to the local fire department and installation of ventilation equipment are required.

Note 1: The power outage backup time is the initial value in an ambient temperature of 25°C. Also, the applicable battery is a small valve-regulated lead-acid battery with an expected service life span of about 5 years (25°C).
Note 2: The height of the battery panel includes the channel base height of 50 mm.

Customizations other than the above batteries are also possible. Please contact us for more information.
