ATYSC30 POWER SUPPLY SOCOMEC
ATYSC30 POWER SUPPLY SOCOMEC – Advanced Automatic Transfer Switch (ATS) Control Relay
The ATYSC30 POWER SUPPLY SOCOMEC (part of Socomec’s ATyS controller family) is a modular automatic transfer switch controller and power monitoring relay designed to manage automatic source switching between main utility supplies and standby diesel generators. Equipped with dual AC power supply inputs and optional DC auxiliary power terminals (9 to 30V DC), this intelligent controller continuously monitors three-phase or single-phase networks for over/under voltage, frequency shifts, phase unbalance, and phase rotation sequence.
Housed in a 6-module wide DIN-rail enclosure, the ATYSC30 POWER SUPPLY SOCOMEC automates power transfer sequences for motorised changeover switches (such as Socomec ATyS or ATyS M series), remote contactors, and motorized circuit breakers. It provides customizable timers for source validation, generator exercise testing under load or off load, and pulse or maintained output logic.
As illustrated in the product image, the front panel features a backlit LCD screen, tactile multi-directional keypad navigation (ESC, navigation arrows, ENTER), front status indicator LEDs (Source 1, Source 2, Mains ON, Fault), dedicated Lamp Test / TEST ON LOAD / TEST OFF LOAD buttons, an RJ45 terminal port for connecting remote display units (ATyS D10/D20), and robust screw terminal blocks.
Key Features of the ATYSC30 POWER SUPPLY SOCOMEC
-
Dual AC Supply & DC Auxiliary Power Input: Accepts power inputs directly from Source 1 and Source 2 networks (184 to 440V AC phase-to-phase), plus an auxiliary DC input (9 to 30V DC) for low-voltage battery backups.
-
Integrated Generator Start/Stop Control: Features a dedicated dry-contact output relay (5 A / 250V AC) to issue automatic start and stop commands to emergency generator sets.
-
Comprehensive Electrical Sensing: Measures voltage, frequency, phase unbalance, and phase sequence across Source 1 and Source 2 with high measurement accuracy.
-
Flexible Control Modes: Programmable output modes support impulse control logic (for changeover switches), contactor logic (maintained outputs), and circuit breaker open/close signals.
-
RJ45 Remote Display Port: Includes an RJ45 communication port to connect external door-mounted display units like the Socomec ATyS D10 or D20.
-
On-Board Test Sequences: Allows maintenance technicians to execute “Test On Load” and “Test Off Load” generator routines directly from the front panel.
Common Applications and Industrial Usage
The flexible power supply options and automation capabilities of the ATYSC30 POWER SUPPLY SOCOMEC make it suitable for critical backup power infrastructure:
-
Data Centers & Telecom Facilities: Ensures immediate, fail-safe transfer from primary utility grid power to standby generator sets during brownouts or grid failures.
-
Hospitals & Healthcare Facilities: Serves as the central ATS controller in life-safety electrical distribution systems requiring compliant source switching.
-
Commercial High-Rises & Shopping Malls: Manages transfer operations between dual utility transformers or utility-to-generator supplies for HVAC, fire pumps, and emergency lighting.
-
Industrial Manufacturing Plants: Drives motorised changeover switches to protect sensitive process automation lines from voltage sags and blackouts.

Installation Guidelines and Best Practices
SAFETY NOTICE: Ensure all mains voltage sources (Source 1 and Source 2) are isolated prior to wiring control terminals.
Power Terminal Protection: Install 5 A gG fuses on all voltage sensing lines (terminals 104, 105, 106, 203, 205) to safeguard the internal power supply circuits of the ATYSC30 POWER SUPPLY SOCOMEC.
Genset Battery Backing: Connect a direct 12V DC or 24V DC auxiliary supply to the DC input terminals to maintain controller screen operation and event logging during total AC blackout.
RJ45 Shielding: Use standard FTP/UTP RJ45 patch cables (maximum 3 meters) when extending the display to an external cabinet door unit (ATyS D10/D20).
