Model 2A10372G90 is an Emerson-Westinghouse industrial switching power supply module customized for Ovation DCS distributed control system, originally manufactured in USA for power plant automation cabinet power distribution application. It serves as core power conversion unit to provide stable regulated DC power for rack-mounted controller, I/O cards and auxiliary relay modules inside boiler, turbine and auxiliary control cabinets of thermal power, nuclear power and petrochemical factories.

This module adopts closed metal casing with integrated radiator structure to improve heat dissipation performance under continuous load operation, terminal strip layout is arranged on front lower side for field wiring connection, with built-in multi-layer surge suppression circuit and EMI filtering components to restrain cabinet internal electromagnetic interference from large motor and switching equipment. Multiple status indicator LEDs are equipped on front panel to display power-on status, normal running condition and fault alarm signal in real time, supporting uninterrupted 24-hour long-term running under severe industrial cabinet working environment and complying with CE, UL and IEC industrial power component safety standards.

Standard input working voltage range covers universal AC 85V~264V alternating current, compatible with domestic and international common industrial cabinet power supply grid. After internal high-efficiency switching conversion, it outputs stabilized DC rated voltage which is configured as standard DC24V version, with fixed rated output current to satisfy the power consumption demand of multiple adjacent rack control modules.

The power supply integrates comprehensive built-in protection functions including overvoltage protection, overcurrent protection, short-circuit auto-shutdown protection and overheat thermal cut-off protection; once output circuit happens abnormal overload or short-circuit fault, the module will automatically lock output to avoid damage to rear-end connected DCS boards and field control loops.

Permitted working ambient temperature inside control cabinet ranges from 0℃ to +60℃, storage temperature spans -40℃ to +85℃; applicable working relative humidity keeps 5%~95% without internal condensation of the module body. Overall mechanical dimension follows Emerson unified cabinet power supply outline specification for standard DIN rail or cabinet fixed installation.

Main application fields include Ovation DCS system cabinet of large-scale thermal power and nuclear power station, boiler fuel supply control cabinet, steam turbine auxiliary protection control cabinet, petrochemical process shutdown interlock cabinet and metallurgy furnace automatic control system, acting as stable power source for core control hardware and on-site signal collection modules.
