Operation 25

Signal connector

This connector provides control and monitoring signal access to the rectifier. Refer to the “Signal Connections” section for connection details.

Power interface edge connector

The rectifier AC, DC and chassis ground interface is made through the rear edge connector. Refer to the “Rectifier and Controller Interface Connections” section for connection and installation details.

Features

The rectifier provides the following operating, monitoring, measurement and control features:

Operating features

Remote voltage sensing

Provision is made to extend the sensing leads to the battery or to the charge/discharge bus (operation without batteries) of the plant. The opening of either sensing leads will not result in a voltage increase at the rectifier output terminals.

Current limiting

The rectifier will automatically limit the output current to 17.5 to 20 A (MPR15) and 25.5 to 30 A (MPR25). Extended periods of operation in the current limiting mode, and repeated transitions between constant-voltage operation and constant-current operation have no detrimental effect on the performance or service life of the rectifier.

The rectifier is capable of starting when connected across a completely discharged battery without requiring human intervention or operating protection devices.

Transitions from constant-voltage operation to constant-current operation and from constant-current to constant-voltage operation will occur automatically, as determined by the output current. The current limit circuit will continue working in both the float and equalize modes.

Soft start and walk-in

The output current rises from 10% to 90% in 2 seconds (typically).

On the other hand, the MPR15 series is designed for lower flow applications, providing precise pressure control in compact spaces. Despite its smaller size, it maintains excellent performance, featuring low droop characteristics that allow for consistent pressure output even with varying flow rates.

Both series incorporate advanced materials and sealing technologies to enhance their durability and resistance to harsh operating conditions. The body is commonly made from high-grade materials that ensure resistance to corrosion, allowing for longer service life and reduced maintenance needs. Additionally, the regulators feature easy-to-adjust set points, enabling operators to quickly adapt to changing process requirements.

Furthermore, the MPR25 and MPR15 series regulators are designed with safety in mind. They include built-in safety features to prevent over-pressurization, enhancing system protection and operator safety. The design also allows for easy installation and servicing, contributing to lower operational costs over time.

In summary, the Emerson MPR25 and MPR15 series pressure regulators stand out for their precision, durability, and efficiency. With their advanced diaphragm mechanism, robust construction, and user-friendly features, they meet the needs of a diverse range of industrial applications, ensuring reliable operation in every environment. Whether for high-demand or compact applications, these regulators are an excellent choice for maintaining the integrity and performance of pressure control systems.
