Product Description

The Alstom MPS022 is a high-capacity AC/DC power supply engineered for VMEbus racks and heavy-duty industrial control panels. Designed for global industrial infrastructure, it accepts a wide AC input (90–264 VAC) or high-voltage DC (130–350 VDC), delivering a regulated 24 VDC output at up to 20 A. Its ultra-low ripple (<10 mVpp) ensures reliable operation for sensitive control and communication modules.

Featuring active Power Factor Correction (PFC) and robust protection circuitry, the MPS022 safeguards against over-current, over-voltage, short-circuits, and overload conditions. Its 6U Eurocard form factor ensures seamless integration into standard 19-inch Schroff or compatible racks.

• Metal processing and heavy industry requiring high-reliability power

Frequently Asked Questions

Q: Is the MPS022 compatible with standard Schroff sub-racks?
A: Yes, the 6U Eurocard form factor allows the MPS022 to integrate seamlessly into standard 19-inch Schroff or compatible rack systems with appropriate backplane connectors.

Q: How does the unit handle high ambient temperatures?
A: The MPS022 operates up to +70°C. In high-load or high-temperature scenarios, internal thermal protection prevents damage. Forced-air rack cooling is recommended for maximum longevity.
