Technical Specifications Wide range input, 24VDC regulated output. Operating temperature: -40℃ ~ +70℃, built-in overvoltage, overcurrent and short-circuit protection.

Functional Features Voltage regulation, parallel redundant operation, fault alarm, load sharing, automatic backup switching.

Application Scenarios Important generator control racks, gas turbine control systems, equipment requiring uninterrupted control power.

Performance Parameters Low output ripple, balanced load sharing, seamless switching during single power failure, high efficiency.

Structural Characteristics Rack pluggable power module, power normal and fault LED indicators, built-in cooling structure.

Working Principle Two power modules share the load in parallel normally. When one module fails and stops outputting, the other unit instantly takes over the total load without power interruption for the control rack.

Installation Requirements Install in dedicated power slots of the rack, reserve enough ventilation space for heat dissipation.

Usage Notes Test redundant switching function regularly, replace faulty power module immediately once alarm occurs.
