LINOVISION Industrial Gigabit BT90W PoE Switch and PoE Optional DC Power SFP DIN Rail PoE Powered Switch Support 820ft Long Range PoE 4-Port

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Industrial PoE Pass-Through Switch - Powered by a POE switch or PoE injector to pass PoE power to other PoE devices such as VoIP phones or cameras. Also called PoE power switch. No local power adapter required 4CH BT90W PoE Extender - 1 x IEEE 802.3af/at/bt POE input port, up to 90W. 4 x IEEE 802.3at/af/bt PoE output ports, each port max 90W. Total POE budget is up to 75 W (90 W POE input) or up to 120 W (DC input). Also provides 1 * 1000BASE-X SFP port and 1 * Relay port. Optional DC Power Supply - Dual 48-57V DC redundant power inputs: Power 1 (Main), Power 2 (Backup) 250 Meter PoE Extension - Extend your PoE and Ethernet an additional 100 meters at Gigabit speeds and 250 meters at 10Mbps in CCTV mode. Set the PoE switch to CCTV mode using the DIP switch on the panel. Standard PoE - Unlike some software emulated PoE, this PoE extender adopts a hardware IEEE802.3af/at/bt PoE chipset and is compatible with both Mode A and Mode B PD devices There is a gender. To prevent damage to standard PD devices, follow the PD Detection -＞ Classification Type -＞ Power On procedure. Industrial Design - Fanless metal shell design. Wide operating temperature -4°F ~149 °F (-20°C ~ 65°C); DIN rail/wall mount installation, 6kV surge resistant, 8kV ESD protection. QUICK-PoE - Provides PoE power as soon as the switch powers up without waiting for switch system software control. This is a unique feature of many IoT devices that rely on uninterrupted operation.
