What chassis is the Dell CRMRT compatible with?

The CRMRT is designed specifically for Dell N3200 modular network switch chassis, providing primary or redundant power for control modules, supervisor cards, line cards, and fabric interconnects in 1U rack deployments.

What efficiency rating does this PSU achieve?

80 Plus Platinum certification with >94% efficiency at typical loads, reducing energy waste and heat compared to Gold or standard PSUs. Ideal for dense racks where cooling capacity is limited.

Is hot-swap replacement supported?

Yes, fully hot-swappable with automatic load balancing in N+1 redundant setups. PSU detection signals allow safe online replacement without powering down the N3200 chassis or interrupting network traffic.

What is the input voltage range?

Universal 100-240V AC input at 50/60Hz with active PFC, supporting global deployments. Inrush current limited to 45A peak for compatibility with standard PDUs and UPS systems.

What protections are included?

Comprehensive safeguards: OVP, UVP, OCP per rail, SCP, OTP with hysteresis and auto-recovery. Ensures system protection against power anomalies common in enterprise data centers.

What airflow direction does it use?

Normal airflow (front-to-back) matching standard Dell N3200 chassis cooling design. Optimized intake from rack front, exhaust to back for efficient thermal management in closed racks.
