Convert the external high-voltage direct current (such as a 110VDC system) into a stable low-voltage power supply required by the system, ensuring that all monitoring modules are properly powered.
By means of voltage regulation and filtering mechanisms, the influence caused by fluctuations in the input power supply is eliminated.
Supports dual power redundancy configuration. Automatically switches to the backup power supply in case of main power failure.
Integrates multiple protection mechanisms (such as overvoltage, overcurrent, and short-circuit protection), and provides feedback on the operating status through status indicator lights.
Below are some of the key features and functions of this module:
High Voltage DC Input: The 115M7750-01 supports high voltage DC inputs ranging from 88 to 140 Vdc.
Stabilized Power Supply: The module provides a stabilized power supply to ensure proper operation of the 3500 Series Monitoring System
Protection features: Includes over-voltage protection, over-current protection, and short-circuit protection to prevent damage to the power module and connected equipment
Cooling Methods: Typically designed with natural or air cooling to accommodate temperature variations in an industrial environment
Mounting: Designed in standard sizes to fit into 3500 series racks for easy integration into existing systems.
Certifications and Standards: Complies with relevant industrial safety standards and certifications to ensure product reliability and safety.
Half-height module design: The 115M7750-01 is a half-height module and must be installed in the designated slot on the left side of the rack.
Operating Temperature Range: Reliable operation in extreme environments, with an operating temperature range of -40°C to +85°C, enhances system uptime and efficiency.
Environmental compliance: CE compliant for safety and quality assurance
