The TDK-Lambda Sirius CSM200 is a modular, fan-cooled power supply engineered for flexible deployment across industrial automation, medical equipment, and test and measurement systems. It features configurable output modules supporting up to 4 simultaneous outputs with tailored voltage and current combinations. Universal AC input and multiple cooling options—including no fan, single end fan, dual end fans, or single top fan—accommodate diverse thermal and spatial requirements. Note: This is a legacy product not recommended for new designs.

Output & Environmental
• Output modules: Voltage range 3.3 V to 12 V; currents to 25 A (main outputs)
• Operating temperature: 0°C to 50°C
• Storage temperature: −40°C to 85°C (maximum 12 months)
• Parallel operation: Method (B) available for backup systems; requires identical output voltage settings and blocking diodes rated above load current
– Key Features
• Configurable multi-output architecture enabling voltage/current tailoring
• Fan-cooled thermal management with flexible cooling topology selection
• Modular design supports up to 4 outputs; CSF250 variant extends to 6 outputs
• 440 Hz operation possible with reduced PFC (requires factory consultation)
• Output power derating required for input voltages below 115 VAC
– Typical Applications
• Industrial automation systems
• Medical device power platforms
• Test and measurement instrumentation
• Backup power configurations via parallel operation
– Compatibility & Integration
Parallel-connected units require output voltage adjustment to compensate for blocking diode forward voltage drop. Identical voltage settings across all paralleled supplies are mandatory. 440 Hz operation and non-standard input voltage ranges require factory consultation.
