SGDB Series Power Distribution Units (PDU) are designed and manufactured for use in industrial automation and automatic test systems. PDUs are completely software controlled. Current and voltage measurements are made with high precision for all output channels. Current limit can be determined for each channel. When the specified limit current is reached, it can be preferred to turn-off the channel automatically or keep it open and warn the user. 

These Units are designed as solid state in modular structure and in BPS configuration. Each 5/6 channel is controlled by 1 microprocessor. Therefore, when a channel has reached the set limit value, programmed reaction is performed in a short time around 10 microseconds.

The unit's main processor continuously monitors all channels and communications with submodules during normal operation. In this way, if a situation that cannot be controlled due to any malfunction (component, etc.) occurs, the input voltage is isolated from the output very quickly. This isolation is provided by high capacity circuit breaker(s) placed at the input. 

This isolation mechanism can also be triggered both by the physical Emergency Stop Button and the soft-button on the PDU Manager software. More than one PDU can be controlled with a single Emergency Stop Button by making a chain connection with the Emergency Stop Connector on the unit. In addition, each output channel is also protected by a thermal fuse. 

IP address and similar basic settings can be made when necessary, via the Serial Interfaces on the front panel of the unit. In addition, embedded software updates can also be made with these interfaces, and low level detailed information is obtained about the status of unit’s subcomponents when necessary. PDU tests itself during startup. These test stages can also be monitored via those serial interfaces. 

The front panel also includes a time counter that shows how long the unit has been active. Besides, the LED indicators for; input voltage, network connection, data communication and erroneous situations, are also on the front panel. There are also output LED indicators which are directly connected to each output channel. 

With the PDU Manager software supplied with the unit, the output channels of one or more PDUs can be included in different turn-on/off scenarios. With the 4-level scenario structure, many channels and sub-scenarios can be created/included within each other.

PDU Manager software keeps detailed measurement records at 1/3 seconds intervals as well as the turn-on/off times of channels. Thanks to this data collection capability, it is possible to retrospectively examine how much the systems fed from the PDU, draw current at any given moment.
