300W Power Supply

300 watt dual ATX power supply.

Form Factor: Accessory
Part Number: OSS-ATX-PS-DUAL300

Product Features

  • ATX 300 watt output power
  • hot swap, hot plug ability
  • n+1 redundancy
  • Balance load sharing design
  • Remote sensing design
  • 6 outputs: 5V, 12V, -5V, -12V, 3.3V and +5VSB
One Stop Systems PS-ATX-300-AC-DUAL is an n+1, hot-swappable redundant power supply. It offers 300 watts of output power in a compact size. Each power module is designed with +3.3V, +5V, +12V, -5V and 5VSB circuits. The unit also provides a warning sub-system, including LED display, buzzer alarm, and TTL signal and also indicates the status of the power system and DC fan. When all the power modules are at normal condition, it balances the load share through its parallel design, which gives the power system increased reliability.

Specifications

Dimensions: 86mm tall, 150mm wide, 220mm deep
Input  
Voltage (sinusoidal) Full range — 90~264 VAC (with +-10% tolerance)
Frequency 47Hz — 63Hz (=-3Hz)
Steady-state current 6/3 amps maximum at any low/high range input voltage
Inruch Current 60/80 amps @ 110/220VAC (at 25 degrees ambient cold start)
Power factor correction PFC can reach the target of 95% @110V, full load, following the standard of IEC 1000-3-2, class D
   
Output  
Power Output +5V @ 25A, +12V @ 16A, -5V @ .5A, -12V @ .5A, +3.3V @ 14A, +5VSB @ 1.2A
Regulation All output voltages @ +-50mV
Ripple and noise +5V @ 50mV (P-P), +12V @ 120mV (P-P), -5V @ 120mV (P-P), -12V @ 150mV (P-P), +3.3V @ 50MV (P-P), +5VSB @ 50mV (P-P)
Overshoot Any overshoot at turn on or off shall be less than 15% of the nominal voltage value.
Efficiency Power supply efficiency typical 63% at 115V full load.
Remote on/off control The power supply DC outputs (with the exception of +5VSB) shall be enabled with an active-low TTL-compatible signal ("PS-ON"). When PS-ON is pulled to TTL low the DC outputs are to be enabled. When PS-ON is pulled to TTL high or open circuited the DC outputs are to be disabled.
