Product Features
High Reliability and Stability
- Adopts advanced power conversion technology to ensure extremely low output voltage and current loss (<1%), maintaining stability even under high temperature or heavy load conditions.
- Equipped with overcurrent, overvoltage and short-circuit protection functions to effectively prevent the spread of electrical faults.
Modular Design
- Designed as a half-height module, it can be directly inserted into the dedicated left slot of the 3500 system for easy installation.
- Supports “hot-swappable” feature, which means it can be replaced while the system is running, or a second module can be installed as a backup power supply.

Environmental Adaptability
- With IP67 protection, it can work normally in high humidity (95% non-condensing) and dusty environments, making it very suitable for heavy industry scenarios such as petrochemical, electric power and metallurgy.
Structure and Composition
- Power Conversion Unit: The core internal component, responsible for converting the input voltage (usually 85-264VAC or 24VDC) into a stable 20-30V DC output.
- Heat Dissipation System: A necessary heat dissipation device for large industrial power supplies (usually air-cooled), used to maintain the module’s operating temperature between -40℃ and +70℃.
- Terminals: Equipped with input power terminals and output terminals; some models support RS485 or Ethernet communication interfaces for monitoring power supply status.
Main Application Fields
- Power Plants and Energy: Provide continuous power supply for steam turbines, gas turbines and generator sets, and monitor the vibration status of bearings and blades.
- Industrial Manufacturing: Applied to condition monitoring of continuously operating equipment such as compressors, pumps and fans.
- Petrochemical Industry: Provide power guarantee for online monitoring of key equipment in high-temperature and high-corrosion environments.
