The power supply logic shall latch into the off state requiring a power on cycle to be performed by the operator. The power supply will turn-off within 20 ms of the occurrence of the overload. The -5 Vdc and -12 Vdc outputs will be internally current limited. CONDITIONS LIMIT 110 -240 VAC input When output power is over to 120% 5.2 Over Voltage Protection The power supply shall latch off if the +5 VDC or 3.3VDC or +12 VDC maximum voltage exceeds the limits shown.

In such a case, the power supply shall power up and stabilize. However, minimum load required 3A for +5V and 1A for +12V. 5.5 5VSB (Standby) The 5VSB output is always on (+5V Standby) when AC power is applied and power switch is turned on. The 5VSB line is capable of delivering at a maximum of 5A for PC board circuit to operate. 5.6 PS-ON (Remote ON/OFF) PS-ON is an active low signal that turns on the entire main power rail including 3.3V, 5V, -5V, 12V & -12V power rails. When this signal is held by the PC board or left open circuited, outputs of the power rails should not deliver current and should be held at a zero potential with respect to ground. Power should only be delivered to the rails if PS-ON signal is held at ground potential. This signal should be held at +5VDC by a pull-up resistor internal to the power supply. Power On P1-PIN #14 Power Switch P1-PIN #14 PS-ON PS-ON ON L ON IN OFF H ON IN OFF X ON OUT OFF X OFF X 5.7 3.3V Sense A remote 3.3V sense line can be added to the P1 connector Pin2 to allow for accurate control of the 3.3VDC line directly at motherboard loads. Due to potential voltage drops across the connector and traces leading to the motherboard components, it may be advantageous to implement a 3.3V sense line that remotely monitors the 3.3VDC power level at the load on the motherboard. 6.0 Physical Characteristics 6.1 Size 100*70*190mm 6.2 Mounting Requirements See Figure 6 6.3 Weight 1.4 Kg 6.4 Cooling Fans: SUNON (KD1206 PTV1), or equivalent or better.
