Switching between a primary source of power, usually the grid to a secondary source (in many cases, generators), has become a crucial preventative measure in order to avoid major disruptions or even complete loss of life, making it a vital step to ensure mission-critical systems are powered on, during the event of primary power failure. So, why do people invest heavily in ATS products?
The main reason is that they are looking for uninterrupted business operations.
An ATS ensures the continuous and reliable supply of power, no matter what the power source is, by safely and rapidly switching between supply sources.
A number of manufacturers have designed and supplied various types of Automatic Transfer Switches to satisfy this requirement. Since technology is advancing at a rapid pace, OEMs are now producing more compact, efficient, intelligent and faster transfer switches with much higher reliability.
One OEM in particular has recently appointed Unipower UK Ltd. (T/A Charter Controls) as its UK & Ireland agent is Elmeasure, with a global presence in over 50 countries, sales offices in six countries, and five million collective products in operation worldwide.
Elmeasure provides an entire range of auto changeover solutions (motorised and solenoid-based ATS), ranging from 63A-6300A, with open/closed and delayed transition modes, featuring a high-end micro-processor-based ATS controller for programming/monitoring and controlling.
IoT-enabled automatic transfer switches that offer easy programmability, and connection to any IoT platform for smart remote monitoring, are optional.
Elmeasure motorised changeover provides the unique features of an inbuilt high-end micro-processor-based AMF controller, with incomer level Source 1 and Source 2 protection, including under/over voltage, under/over frequency, phase sequence, and optional overload tripping logic.
Ranging from 63A-3600A, it includes features exceeding expectations, including the inbuilt removable key switch which enables operators to switch between auto/manual modes, and optional RS485 Modbus protocol communications for cloud connectivity, allowing monitoring and control derived from master/slave architecture (PLC, SCADA).
Elmeasure’s automatic transfer switches offer a high capacity to withstand a short circuit and fire alarm/external fault tripping. These transfer switches also offer real-time system voltage and frequency, while intelligently monitoring source healthiness and output for both sources simultaneously.
There is no requirement for a separate external power to power the ATS and it can be set to switch single-phase or three-phase supplies. The inbuilt microprocessor controller, with diesel generator start/stop option, offers the safest changeover during failure of a primary source.
Transfer delays can be set from three seconds to 600 seconds that can be set up using a remote display unit, which can also act as a front panel to enable the user to change parameter settings without opening the control panel door.
These units also carry an AC 33B utilisation category and are in accordance with IEC 60947-6-1.
Customer feedback so far has been very positive, some of which highlight a cost-effective solution that offers time saving in installation and set-up, a compact design allowing space saving, and quiet operation.
