ETASIS Electronics EFRP-S657 650W server power supply

SKU CH-H3W4-VA9YJ MPN EFRP-S657

A 650 W redundant server power module with 85 % typical-load efficiency, 16 ms hold-up at 80 % load and over 100 000 hours MTBF

  • 650 watts delivers reliable server power
  • Redundant module design keeps systems running during failure
  • Over-voltage, over-current and short-circuit protection safeguards hardware
  • Over-temperature protection and no-load operation extend unit life
  • MTBF exceeds 100,000 hours for long-term dependability

650W redundant server power module

The ETASIS Electronics EFRP-S657 is a 650W redundant power supply module built for 1U server chassis. It delivers high-efficiency power conversion with efficiency up to 85 percent at typical load. The unit includes short-circuit, over-current, over-voltage and over-temperature protection. A mean time between failures exceeding 100,000 hours supports continuous operation in rack environments.

ERP1U form factor and redundancy check

Confirm that the target chassis accepts ERP1U redundant modules and provides the matching hot-swap bay. Verify the system backplane supplies the required power-distribution connectors for this module. Ensure the total server draw stays within the 650W capacity of a single module for full redundancy. No-load operation is supported for testing or staging without a full system load.

16ms hold-up and thermal protection

Hold-up time is rated at 16ms minimum at 80 percent load, giving the system a brief ride-through during input interruptions. Over-temperature protection shuts the module down if internal temperatures exceed safe limits. Efficiency of 85 percent or less at typical load means a portion of input power becomes heat that the chassis airflow must remove. Acoustic output will depend on the server fans pulling air through the module.

商品問答

What comes in the box with the EFRP-S657 and what must be sourced separately?

The module itself is supplied; a compatible 1U redundant chassis, power cables and any rail kit are not included and must be obtained separately.

How do I decide which EFRP-S657 version or capacity to select?

This model is a single 650W ERP1U module; choose it when your redundant chassis requires a 650 watt hot-swap unit and add a second module for N+1 redundancy.

What does the 650W rating mean once the supply is installed in a server?

It can deliver up to 650 watts continuously with at least 85 percent efficiency at typical load, 16 ms hold-up at 80 percent load and full protection circuits active.
