features and benefits
The NS-205PFC-24V is a 4-port unmanaged PoE (PSE) with 1 fiber port switch; it supports 4 PoE ports which are classified as power source equipments (PSE).
The NS-205PFC-24V makes centralized power supply come true and provides up to 15.4 watts of power per PSE port.
Using fiber optics, you can prevent noise from interfering with your system and supports high-speed (100 Mbps) and high-distance (up to 2 km) transmissions.
The NS-205PFC-24V is designed with 24 VDC to 48 VDC boost for PoE application where 48 VDC power supply is not available.
- Provides 1 x 100-FX fiber port plus 4 x Ethernet ports
- Each port supports both 10/100 Mbps speed auto negotiation
- Store-and-forward architecture
- Full duplex IEEE 802.3x and half duplex backpressure flow control
- 4 PoE ports with Power Sourcing Equipment (PSE) operation
- Automatic MDI/MDI-X crossover for plug-and-play
- Auto-detection of PD (powered devices) and automatic power management
- Over-temperature, over-current and over/under-voltage detection
- Supports operating temperatures from -30 ~ +75 °C
- Multi-mode, SC Connector Fiber supports
- DIN-Rail Mounting
