Note:
1. The combined total power from +5V and +3.3V shall not exceed 150W.
2. Noise Test – Noise bandwidth is from DC to 20 MHz.
3.Ripple frequencies greater than 1MHz shall be attenuated by the measurement
System.
4.Add 0.1uF/10uF capacitor at output connector terminals for ripple and noise
measurements.

2.3
PS-ON
Remote On/Off Control:
When PS-ON is pulled to TTL Low, the DC output is to be enabled.
When PS-OFF is pulled to TTL high, the DC output is to be disabled.
2.4
PW-OK
PW-OK is power good signal and should be asserted high by the power
supply to indicate that +5VDC and +3.3VDC output are above the under
voltage thresholds of the power supply TTL. compatible signal out with
100ms to 500ms.
Timing of PS-ON, PW-OK, and Germane Voltage Rails
Although there is no requirement to meet specific timing parameters,
The following signal timings are recommended:
2ms≦T2≦200ms
100ms≦T3≦500ms
T4＞1ms
T5≦10ms
2.5 Efficiency:
≧
73﹪at full load. (Normal Line)
2.6 Hold-Up Time: 16ms at maximum load & normal input voltage.
3.PROTECTIONS
3.1 OVER-VOLTAGE PROTECTION
Standard on +5.0V output, set at 6.25VDC ± 075VDC.
3.2 SHORT CIRCUIT PROTECTION
A short circuit placed between the DC Return and the output shall cause
No damage and the power supply shall shutdown.
3.3 OVER POWER PROTECTION
The power supply shall shut down when output power exceeds 130﹪to 160﹪
of full load and require a power on cycle be performed by the operate
3.4 NO LOAD OPERATION
No parts shall be damaged on the power supply.

5.2 LIFE EXPECTANCY OF FAN
40,000 hours at 40℃
6. AGENCY APPROVALS
CB、CE、TUV、UL、BSMI、CCC.
Please visit our website and get the latest safety certificate.
7. EMI /RFI
CB、CE、TUV、UL、BSMI、CCC、C-Tick.
Please visit our website and get the latest EMC certificate.
8. INSTRUCTIONS
The set still works properly even if either unit is removed. The removed unit can’t
be used in other machinery nor for other purpose. When one unit breaks down, it’s
LED will blink, buzzer will sound. Push the Reset button and buzzer will stop.
REDUNDANCY Offer redundant function for power system and mutually backs
up the outputs. A zero transfer time when backup takes place.
HOT-SWAP
The power system provides a Hot-Swap function. This means
when either one of the redundant power supplies fails or breaks
down, you can easily replace failed unit without any interference
to the system.
BUZZER
A warning buzzer sounds when any one of the power supplies
fails. The warning buzzer is reset table from reset switch either
the one in front control panel or the one on the rear side.
LED’S
The warning LED’S can be found either on the rear side or the
control panel of the power system. Tells if one of the two power
supplies has failed, by LED blinking.
HOT-PLUGGABLE
The power system provides a Hot-Pluggable function
This method allows the power units in the Disk Array/
File Server to be removed or inserted very easily without

9.HOT-SWAP PROCEDURES
Please refer to the followings when either one power supply unit is fount defective.
A) Locate
the defective power supply by examining the individual LED on the
power unit or the LED on the front control panel if LED is Blinking.
B) Unlock & Remove
the defective power supply unit.
C)
Replace a new GOOD power supply unit, Insert the power supply into the
power system chassis in position & it will auto Lock-up.
D)
Turn on the new power supply unit.
E)
Check the module LED which indicate the power and LED of total power
system status, Both LED shall Have steady life.
