Emerson / Artesyn / Astec CVN300-96P01A-01 Power Supply

The Emerson/Artesyn/Astec CVN300-96P01A-01 is a single-phase AC-to-DC power supply designed for entry-level server computer systems and compliant with Server Systems Infrastructure (SSI) specifications. This power supply features internal cooling via a variable-speed fan, which can also contribute to system cooling, and includes fan control and monitoring signals. It supports universal input voltage ranging from 90VAC to 264VAC and offers multiple output channels, including an auxiliary output, with features such as output voltage tracking, remote sensing, and comprehensive protection mechanisms.

### Technical Specifications

* **Product Type:** AC-to-DC Power Supply
* **Series:** CVN300
* **Model:** CVN300-96P01A-01
* **Application:** Entry-level server computer systems, industrial, commercial, and telecommunications equipment.
* **Compliance:** Server Systems Infrastructure (SSI) specifications, EN6100-3-2, UL, CSA, VDE, FCC Class B, CISPR Class B.

### Electrical Specifications

* **Input Voltage Range:** 90VAC to 264VAC (Universal Range)
* **Input Current:** Less than 5 Arms steady state at minimum line (90VAC) and maximum load.
* **Active Power Factor Correction:** Not explicitly stated for this model, but similar series (µMP) feature it for EN61000-3-2 compliance.
* **Inrush Current Limiting:** Active inrush current limiting is utilized. Maximum cold start inrush current is 65A at 264VAC and 25ºC ambient.

### Output Characteristics

* **Total Output Power:** Not to exceed 300W continuous power.
* **Combined Power (3.3V & 5V Outputs):** Maximum of 167W.
* **Output Channels:**
* Output 1: +5V @ 26A
* Output 2: +3.3V @ 16A
* Output 3: +12V @ 10A
* Output 4: -12V @ 0.5A
* Output 5 (Auxiliary): +5VSB @ 0.8A
* **Output Voltage Tracking:** (+3.3V, +5V, +12V)
* The +3.3V and +5V outputs track each other during turn-on, with the difference not exceeding 2.25V.
* The +3.3V, +5V, and +12V outputs reach regulation within 100msec of each other.
* **Remote Sensing:** On +3.3V output.
* **Output Regulation:**
* Output voltages reach nominal settings within 0.5 seconds after power on.
* Output voltage rises from 10% to within regulation limits in a maximum of 70msec when operated into full load on each output.
* Output voltages remain within regulation limits for defined load steps with slew rates not greater than 0.2A/µsec, bound by repetition rates of 50Hz to 10kHz.
* **Ripple and Noise:** Specific values not detailed in provided snippets, but typical for such power supplies.

### Protection Features

* **Short Circuit Protection:** Latching on all output channels. If the +5VSB output is shorted, the power supply will shutdown, disabling all outputs.
* **Overcurrent Protection:** Latching on all output channels. Defined as a 10A/sec current ramp from full load. Adheres to 240VA limits as defined in CSA C22.2 No. 234, Level 3.
* **Over Voltage Protection:** Latching on all output channels.
* **AC Brownout Protection:** Operation below 90VAC will not damage the unit, but performance specifications are not guaranteed.

### Control and Diagnostic Signals

* **PS-ON Signal:**
* Enables output channels (+3.3V, +5V, +12V, -12V) when driven LOW (0 to 0.8 Vdc with respect to COM).
* HIGH state (2.0 to 5.25 Vdc or open circuit) disables outputs.
* Internally pulled up to +5VSB via a 1k ohm resistor.
* Includes de-bouncing provisions to prevent oscillation at start-up.
* **PW-OK (Power Good) Signal:**
* Asserted HIGH by the power supply to indicate that all outputs are above regulation limits.
* **FanM (Fan Monitor):** Fan control and monitoring signals are provided.

### Thermal Characteristics

* **Cooling:** Internally cooled with a variable speed fan.
* **Operating Temperature:** Full load operation is supported at a maximum ambient temperature of 50ºC at an altitude of 10,000 ft.
* **Overtemperature Control:** An integrated thermistor initiates internal control over fan speed in the event of an overtemperature condition.
* **Thermal Protection:** The unit does not have built-in thermal protection to shut down the power train in case of fan malfunction, high ambient temperature, or abnormal overloading.

### Physical Characteristics

* **Dimensions:** 5.51 x 5.90 x 3.90 inches (Depth x Width x Height).
* **Enclosure:** Enclosed unit.
* **Mounting:** Secured via mounting holes on the base of the rear side and four mounting holes on the front panel.

### Compatibility

* **Server Systems Infrastructure (SSI):** Compliant with entry-level power supply (EPS) specifications.
