PRODUCT OVERVIEW

Built for reliable, continuous power delivery.

The CRPSD1300 is designed for systems using −48V DC-style power architecture instead of standard AC input. It is suitable for telecom racks, network infrastructure, edge computing platforms, battery-backed DC systems, and compact server equipment where DC input compatibility, stable 12V output, airflow flexibility, and compact CRPS integration are important.

Plan the CRPSD1300 output wiring around the actual current demand: keep conductors short, use low-resistance terminations, separate power paths from sensitive signal wiring, and preserve access for retightening and inspection. Arrange the enclosure so heat from neighboring components cannot collect around the supply or its connection points.

Qualify the CRPSD1300 at several load levels, measuring voltage at both the supply terminals and the equipment input rather than relying only on no-load readings. Record cable drop, connector temperature, and enclosure temperature as baseline values. Later maintenance checks can compare against this record to identify loose joints, rising contact resistance, or deteriorating heat dissipation before they interrupt service.
