Switch mode power supplies: Universal range
The Schneider Electric ABL8RPS/RPM/WPS power supply offer is designed to provide the DC voltage necessary for the control circuits of automation system equipment. Comprised of six products, this range meets the needs encountered in industrial and commercial applications. These compact electronic switch mode power supplies provide a quality of output current that is suitable for the loads supplied and compatible with the Modicon™ M340™, Premium™ and Quantum™ ranges. When used with additional function modules, they help ensure continuity of service in the event of network power outages or application malfunctions. Clear guidelines are given on selecting the function modules and upstream protection devices which are often used with them, and thus a comprehensive solution is provided that can be used in total safety.
The Universal range of Schneider Electric Phaseo™ power supplies must be connected in phase-to-neutral or phase-to-phase for ABL8RPS/RPM, and in three-phase for ABL8WPS. They deliver a voltage that is precise to 3%, whatever the load and whatever the type of line supply, within the ranges:
- 85 to 132 V a and 170 to 550 V a for ABL8RPS
- 85 to 132 V a and 170 to 264 V a for ABL8RPM
- 340 to 550 V a for ABL8WPS
Their very wide input voltage range allows a considerable reduction of parts held in stock and offers a distinct advantage in terms of machine design.
Conforming to IEC standards and UL and CSA certified, they are suitable for global use.
ABL8RPS/RPM and ABL8WPS power supplies are all equipped with a harmonic filter, ensuring compliance with standard IEC/EN 61000-3-2 concerning harmonic pollution.
All the Universal range of Phaseo power supplies have protection devices to help ensure optimum performance of the automation system. Their operating mode can be configured as required by the user:
- Manual reset protection mode: Priority is given to the voltage so as to guarantee the PLC logic states and nominal operation of the supplied actuators.
- Automatic reset protection mode: Priority is given to the current to allow troubleshooting for example, or to help ensure continuity of service until the arrival of the maintenance team.
The Universal range of Phaseo power supplies also has a power reserve, allowing them to deliver a current of 1.5 In at regular intervals. This avoids the need to oversize the power supply if the device has a high inrush current, while ensuring optimum performance of the automation system.
The diagnostics for the Universal range of Phaseo power supplies are available on
the front of the device via LEDs (UOut and IOut) and via a dry contact relay.
All products are equipped with an output voltage adjustment potentiometer in order to be able to compensate for any line voltage drops in installations with long connection cable runs.
These power supplies are designed for direct mounting on a 35 mm DIN rail.
