SPS01 ABB 7760690156 Industrial Switching Power Supply

Product Overview

The ABB SPS01 (Part Numbers: 2VAA008278R001 / 7760690156) serves as a regulated switching power supply unit designed for mission-critical industrial automation environments. This brand-new, original module converts high-voltage AC input into a stabilized 24V DC output to drive ABB controllers, I/O modules, and field sensors. Engineered for high-density control cabinets, the SPS01 maintains consistent voltage regulation under fluctuating load conditions, preventing system resets and protecting sensitive semiconductor components from power surges.

The SPS01 utilizes high-efficiency switching topology to deliver clean DC power:

Engineering Advantages

The ABB SPS01 solves the challenge of voltage instability in remote industrial sites. Variations in mains power often cause legacy power supplies to drop output, leading to controller "brown-outs." The SPS01 features a wide input range (100–240V AC) that automatically compensates for voltage sags and surges, ensuring your AC800M or Symphony Plus system receives a steady 24V DC without interruption.

To maximize cabinet efficiency, the module utilizes a compact vertical form factor, allowing for high-density mounting on standard DIN rails. The IP20-rated housing prevents accidental contact with live terminals while providing sufficient ventilation to maintain a 10A load without excessive thermal derating. Furthermore, the unit incorporates short-circuit and overvoltage protection at the hardware level. If a field-side fault occurs—such as a shorted sensor cable—the SPS01 suppresses the surge and enters a protective mode, isolating the fault and preventing damage to the expensive PLC or DCS processor units upstream.

FAQs

What are the primary differences between the 10A and 20A variants of the SPS01?

The 2VAA008278R001 variant provides 10A of current, suitable for standard controller racks and small I/O clusters. The 7760690156 variant offers a higher 20A output for large-scale systems or high-power field actuators. Both maintain the same 24V DC regulation but differ in their physical footprint and heat dissipation requirements.

Can the SPS01 operate in environments with high ambient temperatures?

Yes. The SPS01 supports an industrial operating range of –25°C to +50°C at full load. For applications exceeding 50°C, ensure adequate forced-air cooling or leave a 20mm air gap between adjacent modules on the DIN rail to maintain thermal stability.

Does this power supply require manual voltage switching for 110V vs 220V inputs?

No. The SPS01 features an "auto-ranging" input stage. It automatically senses the incoming voltage (anywhere between 100V and 240V AC) and regulates the output accordingly, making it globally compatible for all industrial grid standards.

Is this unit compatible with redundancy modules?

Absolutely. You can connect two SPS01 units through an ABB redundancy module to create a 1+1 or N+1 power architecture. This setup ensures that if one power supply fails, the second unit takes over the load instantly with no process interruption.
