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

We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using 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. 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.
