The XT244 and XT1144 are designed for sustained ambient temperatures between −20°C and 50°C, with transients up to 70°C (at 90% maximum relative humidity, non-condensing). Operating the players above 50°C ambient for prolonged periods may reduce the operational lifetime of the product.
Important
Exposing a cold player to warm air at high relative humidity may cause water to condense inside the player, leading to component failure. Damage due to such internal condensation is not covered by warranty. If a player is cold, allow several hours for it to acclimatize to ambient conditions before applying power.
The power supply for the XT244 and XT1144 is 36W (12V@3A). The device will use approximately 1A of power when playing a 4096x2160x60p H.265 (HEVC) source file.
A power budget of 24Watts (or 2A@12V) is available to be shared between peripherals connected to the player. The user should not connect any combination of peripherals that will exceed 2A draw. If more than 2A is drawn, the external power supply may shut down due to over-current conditions. The unit will not be damaged, but it may reboot or not operate properly until the overload is removed.
If the device is being powered by the power supply, the 2A can be shared in any way among the following connectors:
Connector | Maximum Rated Output Currents |
|---|---|
USB 2.0 (Type C) | 1A |
| USB 2.0 (Type A) | 1.5A |
GPIO 3.3V | The nominal current rating for the polyfuse at room temperature is 500mA, although due to the characteristics of the polyfuse, it drops to nominal 330mA at 70C. |
HDMI 5V | 70mA |
IR blaster output | 85mA |
PoE Type 1
When the player is powered via Type 1 PoE, the total available power is reduced to 12W. This leads to several performance restrictions:
- Only one CPU core is operational: Processor-intensive applications have slightly reduced performance.
- Each USB port supplies 100mA of power (one unit load for USB 2.0): This is sufficient for low-power devices such as memory sticks and mice. High-power devices such as hard disks will not operate.
- A player installed with an internal SSD drive should not use HDMI Input: Both peripherals consume significant power.
Note
WiFi is always disabled when a player is powered by PoE.
