1SVR450081R0000 ABB

Product Dimensions：

The 1SVR450081R0000 is a compact, DIN-rail mounted power supply that utilizes advanced switching technology to convert AC or DC input voltages into a clean, stabilized DC output. As part of the CP-E series, it is engineered for "enhanced" performance, meaning it offers a wide input range, making it suitable for global use without the need for manual voltage selection. The unit features integrated protection against short circuits, overloads, and overvoltages, ensuring the safety of the downstream connected equipment. It also includes a "DC OK" signaling output for remote monitoring of the output status.

• Mounting: Standard $35 \text{ mm}$ DIN rail (IEC/EN 60715)

• Standards: UL 508, CAN/CSA C22.2, CE, and RoHS compliant

Product Advantages

One major advantage of the 1SVR450081R0000 is its Wide Range Input, which allows a single model to be used in nearly any country regardless of the local power grid (110V or 230V). The High Efficiency design ensures that very little energy is wasted as heat, which allows for a more compact housing and prevents the heating of neighboring components on the DIN rail.

The Adjustable Output Voltage is particularly useful for compensating for voltage drops in long cable runs to remote sensors. Furthermore, the unit’s High Reliability and Robustness are evidenced by its ability to start up at temperatures as low as $-40\text{°C}$, making it an excellent choice for outdoor control cabinets or unheated industrial facilities. The Integrated Redundancy Support allows multiple units to be connected in parallel using external redundancy modules to increase system availability.

Important Considerations and Precautions

When installing the 1SVR450081R0000, it is vital to maintain Adequate Convection Cooling. The power supply should be mounted vertically, and a minimum clearance (typically $25 \text{ mm}$ above and below) must be provided to ensure airflow; blocking these vents will lead to thermal shutdown or reduced lifespan.

Ensure that the Input Fuse Protection is correctly implemented; while the unit has internal protection, an external miniature circuit breaker (MCB) is recommended on the AC side. Wiring Tightness is essential to prevent high-resistance contacts that can cause localized heating. Also, note that if you are using the Parallel Connection feature to increase power, you must ensure that all units are adjusted to the exact same output voltage to prevent one unit from carrying the entire load. Lastly, do not attempt to open the housing as there are High Voltage Capacitors inside that can hold a dangerous charge even after the power is disconnected.

Product Applications

The ABB CP-E 24/2.5 is a versatile power source used across various automation and infrastructure sectors.

• Control Cabinet Building: Providing stable 24V power to PLCs, HMIs, and signal conditioners in manufacturing plants.

• Building Automation: Powering lighting controllers, HVAC sensors, and access control systems in commercial buildings.

• Machine Tools: Supplying DC power to electromagnetic brakes, clutches, and small DC motors in specialized machinery.

• Water and Wastewater: Used in pumping stations and treatment plants to power remote telemetry units (RTUs) and flow meters.

• Renewable Energy: Providing auxiliary power for control electronics in wind turbine pitch systems or solar tracking controllers.
