– Key Features
• Universal input voltage range eliminates region-specific supply variants
• 2.2 kV isolation provides robust noise immunity and safety margin in mixed-signal environments
• Compact chassis-mount design integrates directly into enclosures without external brackets
• Dual thermal operating modes—natural convection at 60W, forced-air operation extends capacity to 80W
• Multi-agency approvals (CE, CSA, TÜV, UR) streamline regulatory compliance across markets
– Typical Applications
Industrial control systems, laboratory instrumentation, point-of-load power distribution, embedded system platforms, and OEM equipment requiring 12V rails with certified safety isolation.
– Compatibility & Integration
The PSA-60-112 integrates into systems demanding chassis-mount topology. Adequate ventilation—maintaining 10–15 cm clearance from heat sources—ensures thermal stability during continuous operation at rated load.
