1. General

This is the specification of Model GM600-G; it is intended to describe the functions and performance of the mini redundant power supply. The GM600-G 600 watts mini redundant power supply is featured with Active PFC (Power Factor Correction) capability and gold efficiency for 80+ and PMBus function meets IEC61000-3-2 and equips full range Input features.

2. AC input specifications

2.1 AC input voltage, frequency and current (Rating: 100V-240 VAC, 47-63Hz, 8-4A)

The power supply must operate within all specified limits over the input voltage range in Table 1.Harmonics distortion of up to 10% THD must not cause the power supply to go out of specified limits. Base on the minimum voltage and power transfer, the max current calculation as below:

Max Current ≧ (Watt / Efficiency) / Minimum Voltage

2.2 AC inrush current

The power supply must meets inrush requirements of any rated AC voltage, during turn on at any phase of voltage, during a single cycle AC dropout condition, during repetitive On/Off cycling of AC, and over the specified temperature range. The peak inrush current shall be 30/60A @ 115/230 VAC (25℃) per module when cold start and less than the rating of its critical components (including input fuse, bulk rectifiers, and surge limiting device).

2.3 Input power factor correction (Active PFC)

The power factor at 50% load shall be ≧ 0.9 at 230V input voltage.

2.4 Input current harmonics

When the power supply is operated in 90-264 VAC of Sec. 2.1, the input harmonic current drawn on the power line shall not exceed the limits set by IEC61000-3-2 Class A and GB17625.1 standards. The power supply shall incorporate universal power input with active power factor correction.

2.5 Dropout

An AC line dropout of 17mS or less shall not cause any tripping of control signals or protection circuits. If the AC dropout lasts longer than 17mS, the power supply should recover and meet all turn on requirements. The power supply shall meet the regulation requirement over all rated AC voltages, frequencies, and output loading conditions. Any dropout of the AC line shall not cause damage to the power supply. An AC line dropout is defined as a drop in AC line to 0 VAC at any phase of the AC line for any length of time.

3.2 DC voltage regulation, ripple and noise

The power supply output voltages must stay within the following voltage limits when operating at steady state and dynamic loading conditions. All outputs are measured with reference to the return remote sense (Returns) signal. The +5V, +3.3V, +12V, -12V and +5VSB outputs are measure at the power supply connectors references to Returns. The +5V and +3.3V is measured at its remote sense signal (+5VS, +3.3VS) located at the signal connector.

Ripple and Noise shall be measured using the following methods: a) Measurements made differentially to eliminate common-mode noise. b) Ground lead length of oscilloscope probe shall be 0.25 inch. c) Measurements made where the cable connectors attach to the load. d) Outputs bypassed at the point of measurement with a parallel combination of 10uF tantalum capacitor in parallel with a 0.1uF ceramic capacitors. e) Oscilloscope bandwidth of 0 Hz to 20MHz. f) Measurements measured at locations where remote sense wires are connected. g) Regulation tolerance shall include temperature change, warm up drift and dynamic load.

3.3 Timing requirements

These are the timing requirements for the power assembly operation. The output voltages must rise from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The +5V, +3.3V and +12V output voltages should start to rise at about the same time. All outputs must rise monotonically. The +5V output must occur first than the +3.3V output during any point of the voltage rise. The +5V output must never be greater than the +3.3V output by more than 2.25V. Each output voltage shall reach regulation within 50 ms (Tvout_on) of each other during turn on of the power supply. Each output voltage shall fall out of regulation within 400 mS (Tvout_off) of each other during turn off. Figure 1 and figure 2 shows the turn on and turn off timing requirement. In Figure 2, the timing is shown with both AC and PSON# controlling the on/off of the power supply.
