GENERAL DESCRIPTION AND SCOPE This is the specification of Model FSP300-50UCB; AC-line powered switching power supply with active PFC (Power Factor Correction) circuit, meet EN61000-3-2 and with Full Range Input features. Designed and manufactured by FSP GROUP. The specification below is intended to describe as detailedly as possible the functions and performance of the subject power supply. Any comment or additional requirements to this specification from our customers will be highly appreciated and treated as a new target for us to approach. 2. REFERENCE...

(10% TO 90% OF FINAL OUTPUT VALUE, ) 115V-rmsor230V-rms +5Vdc : 20ms Maximum + 7Vdc maximum +16Vdc maximum + 4.5Vdc maximum +5Vdc output: +5.7 Vdc minimum, +12Vdc output: +13.3Vdc minimum, Output short circuit is defined to be a short circuit load of less than 0.1 ohm. In the event of an output short circuit condition on +3.3V, +5V or +12V output, the power supply will shutdown and latch off The power supply shall return to normal operation after the short circuit has been removed and the power switch has been turned off for no more than 2 seconds.(PS/ON) In the event of an output short circuit...

Total output shall not exceed 300 watts , in the event of an output total power condition on output , If the total exceed 150% , the power supply will shutdown and latch off without damage to the power supply. The power good signal is a TTL compatible signal for the purpose of initiating an orderly star-up procedure under normal input operating conditions. This signal is asserted (low) until +5Vdc has reached 4.75 volts during power up. Characteristics: TTL signal asserted (low state) : less than 0.5 V while sinking 4mA. TTL signal asserted (high state): greater than 2.5V-5.25V while sourcing...

Volts variation: Setting time: +5Vsb: 0.1 A , Volts variation: Setting time: +5Vsb: 0.1 A Transient Load Requirements

INPUT FREQUENCY 4.5. Standby Power Consumption (5Vsb): PS_ON# is an active-low, TTL-compatible signal that allows a motherboard to remotely control the power supply in conjunction with features such as soft on/off, Wake on LAN+, or wake-on-modem.

When PS_ON# is pulled to TTL low, the power supply should turn on the five main DC output rails: +12VDC,+5VDC,+3.3VDC and -12VDC. When PS_ON# is pulled to TTL high or open-circuited, the DC output rails should not deliver current and should be held at zero potential with respect to ground. PS_ON# has no effect on the +5VSB output, which is always enabled whenever the AC power is present. (PS_ON# Signal Characteristics) The power supply shall provide an internal pull-up to TTL high. The power supply shall also provide debounce circuitry on PS_ON# to prevent it from oscillating on/off at startup...
