Gutor

DC single system configuration

Components of the basic unit:

Rectifier module
Battery

DC parallel, redundant system configuration

Components of the basic unit:

Rectifier module
Common or individual batteries

Characteristics:

Load distribution, each unit supplies its own load to the overall load
Several units are switched in parallel for higher performance

DC SYSTEM DESCRIPTION

The main components of the DC rectifier / battery loading system are: Transformer, rectifier bridge, a controller and a human-machine interface (control unit with screen).

6-pulse / 12-pulse rectifier module

Its function is to rectifier the AC voltage. The rectifier is designed so that the boost charge voltage itself at 10% mains undervoltage can be achieved at the same time as supplying the load. By using a 12-pulse topology mains power distortion can be reduced by more than 60%.

SYSTEM DESIGN, CHARACTERISTICS AND BENEFITS

UPS technology from GUTOR is designed to satisfy requirements with regard to functionality, security and reliability – the main interests of our customers. It has great system flexibility in terms of system design and meets the technical specifications of customers. We produce all our products to conform to internationally and nationally recognised standards and guarantee the highest levels of quality with ISO9001:2000. Some of the main functions and benefits of the design are as follows:

Clear operating and monitoring of the functioning
Safe operation and maintenance
High level of protection against environmental effects
Highest level of system availability and reliability

Modular Design
Our system design is modular. It enables access to all components from the front as well as from the top. A typical GUTOR UPS unit contains a separate connection field with the input switch and the manual bypass switch. Some components are installed on shelves or hinged panel for simple maintenance.

High integrated control logic
All systems are fitted with micro-processor driven controls, which enable digital processing and the adjustment of all parameters. To guarantee reliable functioning, two independent sources, the mains and the battery, supply the controller with power.

HUMAN-MACHINE INTERFACE

AC and DC systems from GUTOR are fitted with a self-explanatory control unit, a flexible human-machine interface, which displays and monitors the system parameters. The control unit is divided into four parts.

The user-specific mimic diagram displays the current mode of operation and gives information on which part of the system is currently supplying the voltage and which is in standby mode.
Functioning of the system on and off switch with a lamp test button.
The display unit consists of an LCD display, which displays the event recorder, the alarm list, measurements and the mode of operation, and which also has an alarm LED, an acoustic alarm and a keypad.
The alarm display has LEDs, which display system-specific alarm incidents.

INTELLIGENT SYSTEM VENTILATION

GUTOR offers the redundant ventilation concept, “N+1” as standard. In the event that one of the fans fails, the two remaining fans are sufficient to maintain the cooling of the system. With the help of an internal speed sensor, the revolutions of each of the individual fans are also monitored. Should the speed fall below one of the pre-defined tolerance values, an alarm is triggered. The fans can be changed during normal system operation, without any risk to staff or the load.
