1 Introduction

1.1 Scope

This specification defines the performance and characteristic for the model of

SP-ATX-650WTB-PFC-1 power supply.

1.2 General Description

SP-ATX-650WTB-PFC-1 is a switching power supply, 650W self-contained, AC to

DC power source supply suitable for mounting in PC.

1) SPCC 0.8MM ENCLOSURE

2) ONE 12CM FAN

3) Black Paint Case

4) Dimensions:140mm(L)X150mm(W)X85mm(H)

2.1 AC Input

Table 1 list AC input voltage and frequency requirements for continuous operation.

Power Factor Correction (PFC)

SP-ATX-650WTB-PFC-1 (w/ Passive PFC) is facilitated with the universal input

200~240VAC Passive PFC with the PF value 0.65 ≧≦0.8

2.1.1 Input Over Current Protection

Parameter Min. Nom.

Vin Voltage 198 220-230 253

Vin Frequency 50 --- 60 Hzrms

(1)

Nominal voltages for test purposes are considered to be within ±1.0 V of nominal.

Table 1. AC Input Line Requirements

(1)

Max. Unit

The power supply is equipped with a non-reset-able fuse on the AC

input to limit power consumption on a failure within the power supply

module.

2.1.2 Inrush Current Limiting

Maximum inrush current from power-on (with power on at any point on the AC
sine) and including, but not limited to, three line cycles, shall be limited to a
level below the surge rating of the input line cord, AC switch if present, bridge
rectifier, fuse, and EMI filter components. Repetitive ON/OFF cycling of the AC
input voltage should not damage the power supply or cause the input fuse to
blow.

2.1.3 Withstand Voltage

The power supply is capable of withstanding a maximum 1500 VDC

potential between the input and ground for a period of 1 second.

2.1.4 Catastrophic Failure Protection

If a component failure occurs, the power supply will not exhibit any of

the following:

1) Flame

2) Excessive smoke

3) Charred PCB

4) Fused PCB conductor

5) Startling noise

6) Emission of molten material

2.2 DC Output

2.2.1 DC Voltage Regulation

The DC output voltages are remain within the regulation ranges shown in Table

2 when measured at the load end of the output connectors under all line, Load,

and environmental conditions.
