Low Voltage Products ATS021, ATS022 Automatic Transfer Switches ATS021, ATS022 Automatic Transfer Switches ABB presents the new generation of Automatic Transfer Switch, the result of a worldwide experience on low voltage applications. The new generation of ATS family – ATS021 and ATS022 offers the most advanced and comprehensive solution in power continuity. Reliability, safety and intelligence are the top features of the brand new range of ATS family which is in compliance with world standards, simple to configure and fitting all application scenarios. Moreover, the perfect integration with all ABB circuit-breakers and switchdisconnectors ensures a complete coordinated system. Multi-function logic to meet all requirements • ATS family provides the standard logic to monitor the normal and emergency line, sends the commands to the generator and controls the circuit-breakers which have to be switched • Possibility to control a third circuit breaker on bus-tie with the ATS022 • Priority line selectable for the ATS022 No auxiliary power supply required The new ATS family is designed to work without auxiliary power supply. Auxiliary power supply is only required when Dialogue Modbus RS485 is used or in networks with rated frequency of 16 2/3 Hz. Compliance with IEC and EN 60947 The compliance with the standard guarantees the new ATS family to provide the quality and safety that meet all the requirements of automatic transfer. Compatibility with ABB circuit-breakers and switchdisconnectors The ATS family can be fit in perfectly with ABB circuit-breakers and switch-disconnectors, thereby ensuring availability of a complete and coordinated system. Accessories To connect Tmax and Emax circuit-breakers to the ATS, the following accessories are required*. Shunt Opening Release Shunt Closing Release Emax Springs Charging Motor X1 Auxiliary Contact for Signaling of circuit-breaker Open/Closed Tmax T7 Auxiliary Contact for Signaling of overcurrent release tripped Auxiliary Contact for Signaling of circuit-breaker Racked-in (only if withdrawable circuit breaker) Motor Operator Tmax T3 Auxiliary Contact for Signaling of circuit-breakers Open/Closed Tmax T4 Auxiliary Position Contact for Signaling of circuit-breaker Tmax T5 Racked-in (only if withdrawable circuit-breaker) Tmax T6 Key Lock only against Manual Operation for Motor Operator Mechanical Interlock * For more details please consult Emax and Tmax catalogues Dimensions 139 Advanced Operator interface and Communication ATS022 is equipped with a communication unit which allows the integration with supervision systems via Modbus RS485. Graphic display is also provided for ATS022. Applications ATS family is highly suited to use in all emergency power supply systems where a ready-to-install, easy to use and reliable solution is required. Some of its main applications are listed therefore: • Power supply of UPS groups in general • Operating theatres and primary hospital services • Emergency power supplies for civil building, hotels and airports • Data banks and telecommunication systems • Power supply of industrial line for continuous processes 2 160 9,5 5 114 174 91 19,5 115 Ordering Codes Order Code Description 1SDA065523R1 ATS021 Automatic transfer switch control unit 1SDA065524R1 ATS022 Automatic transfer switch control unit Technical Characteristics ATS021 Not Required Auxiliary Power Supply General Rated Voltage, Un Max 480 Vac Max 480 Vac 50, 60 Hz 16 2/3, 50, 60, 400 Hz H mm 96 96 L mm 144 144 D mm 170 170 Type of installation DIN-rail mounting - Door mounting Door mounting - DIN-rail mounting Operating Mode Auto/Manual Auto/Manual Monitoring of the Normal and Emergency lines • • Controlling CBs of the Normal and Emergency lines • • Generator set startup • • Generator set shutdown with adjustable delay • • Bustie - • No-priority Line - • Modbus RS485 Dialogue - • Display - • Degree of protection IP20 IP20 Operating temperature -20 … +60 oC -20 … +60 oC Maximum humidity 5% - 90% without condensation 5% - 90% without condensation Minimum voltage -30% … -5% Un -30% … -5% Un Maximum voltage +5% …+30% Un +5% …+30% Un Fixed frequency thresholds -10% … +10% fn -10% … +10% fn • • EN-IEC 50178 EN-IEC 50178 EN 50081-2 EN 50081-2 EN 50082-2 EN 50082-2 IEC 68-2-1 IEC 68-2-1 IEC 68-2-2 IEC 68-2-2 IEC 68-2-3 IEC 68-2-3 H L Environmental conditions Operating thresholds Test Test Mode Electronic equipment for use in power installations Compliance with Not Required (24-110 Vdc is required only for Modbus dialogue and 16 2/3 Hz system) Frequency, fn Dimensions Features ATS022 Electromagnetic compatibility standards Environmental conditions D 3 ABB SACE A division of ABB S.p.A.
