DSE Auto Transfer Switch - ATS
Overview
An automatic transfer switch (ATS) is different to a generator controller as it only monitors the mains and generator power but does not start the engine. The unit normally sits in a monitor panel and and has connections to the generator controller. When the mains power fails the ATS gives a command to the generator controller to start the generator set. Once the generator set is up and running the ATS then switches over the power from mains to the generator. The ATS will then check the mains to see when the power returns, once the power returns the ATS will switch over the mains and then tell the generator to stop.

The DSE500 is an Automatic Transfer Switch Control Module. It is designed to monitor the incoming AC mains supply (3 phase) for under voltage. Should this fall out of limits the module will issue a start command to the generating set controller. Once the set is available the ATS module will control the transfer devices and switch the load from the mains to the generating set. Should the mains supply return to within limits the module will command a return to the mains supply and stop requesting the generator.
A clear mimic diagram with international symbols and LED indications provide at a glance information as to supply availability and load switching status.
The DSE333 is an Automatic Transfer Switch Controller for genset applications. The module will monitor the voltage and frequency of the incoming AC mains (utiltiy) supply (supports many topologies) and in the event of a failure will issue a start command to the generator control system.
The DSE5560 is an Automatic Transfer Switch and Mains Control Module, designed to automatically synchronise multiple DSE5510’s with single or multiple mains (utility) supplies. The module instructs the DSE5510’s to make precise changes to the generating set outputs. This makes the module suitable for many applications including peak lopping, peak shaving and no break return. The module has the ability to monitor the mains (utility) supply and start and stop the generating sets (being controlled by a DSE5510) upon removal or detection of the mains (utility) supply. The modules operational status is indicated on the LCD display and the front panel LED’s.
The DSE7560 is an Automatic Transfer Switch and Mains Control Module, designed to automatically synchronise multiple DSE7510s with single or multiple mains (utility) supplies. The module instructs the DSE7510s to make precise changes to the generating set outputs. This makes the module suitable for many applications including peak lopping, peak shaving and no break return.

The DSE705 is an Auto Transfer Switch Control Module that has been designed to monitor the mains (utility) supply. When the mains (utility) power fails the module sends a start request to the generator control unit. When the generator is up and running the module transfers the load across. When the mains (utility) returns the module transfers the load back and removes the start command. The generator should then begin it’s shutdown procedure. The module can be configured so that they follow the users pre-set start and stop sequences
The DSE4130 is an Auto Transfer Switch Generator Controller that has been designed to monitor the mains (utility) supply. When the mains (utility) power fails the module sends a start request to the generator control unit. When the generator is up and running the module transfers the load across. When the mains (utility) returns the module transfers the load back and removes the start command. The generator should then begin its shutdown procedure. The Generator Control module can be configured so that it follows the users pre-set start and stop sequences. The DSE4130 enclosure has a closed back.
The DSE332 is an Automatic Transfer Switch Controller for single set genset applications. The module will monitor the voltage and frequency of the incoming AC mains (utility) supply (supports many topologies) and in the event of a failure will issue a start command to the generator control system.
Once the generator is available and producing an output within limits, the DSE332 will control the transfer devices and switch the load from the mains (utility) to the generating set. Once the mains (utility) supply returns to within limits, the module will command a return to the mains (utility) supply and shut down the generator after a cooling run. Various timing sequences are available to prevent nuisance starting on minor supply breaks.
The DSE332 includes a clear back-lit LCD 4-line text display, showing system status and warnings. Red and Green LEDs also indicate operation status. The module includes configurable digital inputs and outputs and is programmable by PC using the user-friendly DSE Configuration Suite Software. Limited programming is also available via the module’s front panel.
