Weight: Approximately 1.39 kg

Environmental Specifications

Operating temperature: –30 °C to +65 °C

Storage temperature: –40 °C to +85 °C

Relative humidity: Up to 95%, non-condensing

Protection & Redundancy

Built-in overvoltage and overcurrent protection

Supports dual redundant power supply operation

Primary and backup modules installed in upper and lower rack slots

Automatic switchover between power supplies

Hot-swappable design: insertion or removal does not affect system operation

Redundant Power Supply Assurance

One module can independently supply the full rack load

When two power supplies are installed (AC and/or DC mixed configurations supported), the system automatically selects the active supply and maintains seamless backup operation

Hot plugging does not interrupt monitoring functions, making it ideal for unattended or critical machinery protection systems

Wide-Range Input Adaptation

175–264 VAC input range compatible with global industrial power grids

Integrated input filtering and surge protection minimize the impact of power grid fluctuations on monitoring system stability

High-Reliability Design

Overvoltage or overcurrent conditions trigger the internal protective fuse (P/N 01720025) to safely isolate faults

Front-panel LED indicator provides real-time power status for rapid identification of power supply abnormalities
