1.2.1Rectifier/Battery Charger

The rectifier/battery charger converts the AC input voltage from the utility source into a DC voltage, supplying the inverter and regulating the charge of the battery system. A capacitor bank filters the DC voltage.

1.2.2	Inverter	The inverter chops the DC voltage supplied from either the
		rectifier/battery charger or the battery system into a three-
	phase AC voltage. An AC output filter is used to achieve a computer-grade sinewave output
	voltage waveform, with a total harmonic distortion of less than 2% under linear-load conditions.
1.2.3	Inverter	During normal operation, the inverter transformer provides
	Transformer	complete electrical isolation between the UPS output to the
		attached load and the utility power source input as well as
		the UPS battery source.
1.2.4	Battery System	The battery system stores energy for use by the inverter.
		The stored energy is utilized in the event that the AC input
	power from the utility source fails, or falls outside of acceptable tolerance.

The battery system may be an MGE battery cabinet designed for operation with the EPS 6000 UPS, or a customer-supplied battery installation.

MGE-supplied EPS 6000 battery cabinets may be a provided as stand-alone enclosures, or as enclosures designed to be mounted adjacent to the EPS 6000 UPS module.

The EPS 6000 comes with a special battery ambient temperature sensor which allows the optimization of the DC voltage level as a function of the temperature, ensuring that the battery is properly charged and preserving its longevity.

1.3Description of SSC The static switch cabinet (SSC) provides an electrical path

between the output of the UPS modules and the load. When the UPS modules are off, the SSC provides power to the load from the bypass AC input source (mains 2). Up to six (6) modules can be connected to the SSC, supporting loads as great as 1,500 kVA. UPS modules may be turned

off individually for maintenance, provided that the remaining modules can support the load.

The SSC incorporates a static bypass switch. A wrap-around circuit breaker (Q2S) in the SSC switches between the UPS module output and the bypass AC input source (when the UPS modules are off). Optionally, the SSC can be provided with its own maintenance bypass cabinet (MBC), allowing the SSC and/or any attached UPS module to be serviced while the load is supplied via the maintenance bypass AC input source.

Introduction

1.4 Options

User’s guide

This section describes options available for the EPS 6000 UPS. Some configurations do not support some options.

Most options must be specified at the time of equipment order; some options can be installed in the field. Contact your MGE dealer for complete information.

Additional battery cabinets

Up to a maximum of four battery cabinets can be supplied for a single EPS 6000 UPS module, making additional back-up time available during power outages.

Input filter

An input harmonic current filter is available for the EPS 6000 UPS. For some power levels, the input filter is installed within the UPS enclosure. For others, the input filter is installed in an auxiliary cabinet.

High interrupting capacity circuit breakers

The EPS 6000 UPS module is normally equipped with circuit breakers rated at 30 kAIC. As an option, these breakers can be provided with a rating of 65 kAIC.

Maintenance bypass

For the UPS modules, maintenance bypass is provided by the SSC, allowing any or all attached UPS modules to be taken off-line while the SSC supports the attached load from its bypass source. As an option, the SSC can be equipped with its own maintenance bypass, allowing the SSC as well as any/all attached UPS modules to be serviced while the load is supported by the maintenance bypass AC input source.

Active RS-232/RS-485

A communications port is available that allows the UPS module or the SSC to be monitored from a remote terminal or computer. For detailed information on the communication features, contact your MGE dealer.
