Key Advantages

Built for Zero-Downtime B2B Applications

8kV Burst Immunity

Engineered to withstand high-energy electrical transients, preventing system lockups and component damage in harsh industrial environments.

Standard 3U Cassette

Fully compliant with 19-inch subrack mechanical standards and DIN 41612 connector interfaces for easy slide-in integration.

Multi-Rail Precision

Independently regulated outputs eliminate cross-talk, supplying clean DC power to mixed analog and digital signal processing boards.

Ultra-Low Ripple

Advanced filtering yields exceptionally low output noise (down to 10mVpp), critical for sensitive sensor and communication systems.

Application Scenarios

Mission-Critical Deployments worldwide

The PSM series is explicitly designed for industrial sectors where power interruption causes significant operational expense or safety hazards:

Traffic Management & ITS: Outdoor traffic controller cabinets exposed to lightning spikes and power line noise.
Railway Infrastructure: Signal stations, switch monitoring electronics, and wayside trackside control equipment.
Industrial Automation: Standardized 19-inch subracks in assembly lines, robot controller panels, and SCADA hubs.
Power Substation & Utilities: High-EMC environments requiring continuous telemetry and breaker control.

Technical FAQ

Frequently Asked Questions

Standard power supplies often pass EMC testing at 2kV or 4kV. However, in outdoor traffic cabinets, substation environments, or rail lines, inductive switching spikes and atmospheric disturbances regularly exceed 4kV. CAMTEC's 8kV protection prevents false system triggers, power supply lockouts, and hardware degradation.

In models like the PSM01502 and PSM02202, internal rails are engineered so that specific outputs can be linked to yield higher DC voltages (such as +24V DC or +30V DC). Consult the technical manual for exact wiring layout and jumper setup.

All PSM 3U 19-inch power supplies are manufactured exclusively in Pfinztal, Germany under DIN EN ISO 9001:2015 quality assurance. Every unit undergoes 100% burn-in and automated safety testing prior to shipment.
