Support PMBus
High Power Density is approaching 10 W/in3
Meet standard 1U size and fit 2U server design

ETASIS ELECTRONICS™ a worldwide leading provider of high-performance switching power supplies, officially unveils EFRP-S500, the latest ATX true redundant solution with high efficiency, high power density, and meets standard PMBus 1.1 design.

High Efficiency
EFRP-S500 is a 80PLUS certified PSU at silver level. This environmental friendly unit also includes active power factor correction and soft-switching for more efficient power delivery. Swapping from an ordinary power supply to an ETASIS EFRP-S500 power supply should pay for itself in a few months.

High Power Density
EFRP-S500 uses 1Ux2U form factor-it measures just 1.6inch(4cm), depth
by 9.8 inch(25cm), wide by 3.2inch(8.2cm).

PMBus for Server Management
In addition to high efficient
and high reliability, EFRP-S500 also incorporates optional Power
Management Bus(PMBus). PMBus is an open standard power-management
protocol that communicates with power converters and server system. The protocol is implemented over the
industry-standard SMBus serial interface and enables programming,
control, and real-time monitoring of compliant power conversion
products. EFRP-S500 supports PMBus 1.1 and includes:
12V output voltage monitoring
12V output current monitoring
12V output power monitoring
5V output voltage monitoring
5V output current monitoring
5V output power monitoring
3.3V output voltage monitoring
3.3V output current monitoring
3.3V output power monitoring

Greater modularity
Use the same EFRP-S500 power module as in ETASIS EFRP-S2500,
EFRP-S3500 and EFRP-S3490 series power supplies; thus simplifies maintenance.
