Lambda / TDK / EMI TCR7.5S300

The TDK-Lambda EMI TCR7.5S300 is a regulated AC-DC power supply module engineered for industrial and laboratory applications requiring stable voltage or current delivery across wide input voltage ranges. It integrates an internal RFI filter with ferrite toroidal chokes and VDE-approved X and Y capacitors to suppress conducted electromagnetic interference, delivering clean power conversion with minimal output ripple.

– Key Features

• Internal RFI filtering with ferrite toroidal chokes and VDE-listed capacitors
• Over-voltage protection with crowbar output, down-programming, and manual-reset circuit breaker
• Tight output regulation across load and line variations
• Low temperature coefficient for stable operation in temperature-variable environments

– Typical Applications

Lab power systems, industrial test benches, rack-mounted supply chains, and OEM embedded power modules where input phase rotation independence and EMI suppression are required.

– Compatibility & Integration

The TCR7.5S300 accepts standard three-phase or single-phase 190–253 VAC input with no phase sequencing requirement, simplifying integration into existing distribution networks. Output specifications and ratings are model-dependent; consult the rating table for your specific output configuration.
