DC INPUT #
You can choose AC power adatper with 12VDC output and 5.5mm x 2.5mm size pin as the power source.
| Input Channel | DC Input Voltage | DC Jack | DC Input Cable Length |
|---|---|---|---|
| 1 | 12V (OVP at 13~13.5V) | 5.5mm x 2.5mm | 350mm |
POWER RATINGS #
The power rating for each output rail is shown in the following table. Maximum 12A continous current is guaranteed in the 12V output rail. Forced air ventilation is required for operating at max load. For fanless or improper ventilation operation derate the output of the 12V rail until PSU temperature falls below 65℃. Peak load should not exceed 60 seconds. Combined max power output should not exceed more than 200 Watts.
| Voltage Rail | Max Load (A) | Peak Load (A) | Regulation |
|---|---|---|---|
| +12V | 12 | 15 | Switched Input |
| +5V | 6 | 8 | ±1.5% |
| +5VSB | 1.5 | 2 | ±1.5% |
| +3.3V | 6 | 8 | ±1.5% |
| -12V | 0.05 | 0.1 | ±5% |
PROTECTION #
OCP, OVP, short circuit and no load operation.
Overload Protection #
The power supply will be shutdown and latch off when load power over 110% ~ 160% of the rated DC output.
Over Current Protection #
The power supply shall have current limit to prevent the +12V, +5V and +3.3V outputs from exceeding the values shown in the following table. If the current limits are exceeded the power supply shall shutdown and latch off.
| Output Rail | Over Current Limit |
|---|---|
| +12V | Switched Input |
| +5V | 8~10A |
| +3.3V | 8~10A |
Over Voltage Protection #
The microcontroller in the PSU monitors all output rails and provides over voltage protection as defined in the following table.
| Output Rail | Minimum (V) | Normal (V) | Maximum (V) |
|---|---|---|---|
| +12V | 13.4 | 15 | 15.6 |
| +5V | 5.74 | 6.3 | 7 |
| +3.3V | 3.76 | 4.2 | 4.3 |
Short Circuit Protection #
An output short circuit is defined as any output impedance of less than 0.1 ohms. The power supply shall shut down and latch off for shorting the +3.3V, +5V, or +12V rails to return or any other rail.
No Load Operation #
No damage or hazardous condition should occur with all the DC output connectors disconnected from the load. The PSU may latch.
I/O PIN DIAGRAM #
The on-board 24pin connector is the standard ATX power connector which can directly plugin to the 24pin ATX power connector on the motherboard. The on-board 5pin is used by the cable set to generate voltages on EPS 12V, SATA and peripheral connectors.
TIMING #
Compliance with Intel ATX specification version 2.01. Remote ON/OFF control is as follows.
- When the logic level “PS-ON” is low, the DC outputs are to be enabled.
- When the logic level is high or open collector, the DC outputs are to be disabled.
- T1: Power-on time. The time from when PSON# is pulled low to when the +12V, +5V and +3.3V outputs are within the regulation ranges. The power-on time shall be less than 500ms (T1 < 500ms)
- T2: Rise time. The output voltages shall rise from ≤10% of nominal to within the regulation ranges within 0.1 ms to 20 ms (0.1 ≤ T2 ≤ 20ms)
- T3: Power good signal turn on delay time (100 < T3 < 500ms)
- T4: Power good signal rise time (T4 ≤ 10ms)
- T5: Voltage input loss to PGOOD hold-up time (T5 ≥ 16ms)
- T6: Power down warning (T6 ≥ 1ms)
