The product is ideal for Telecom and Networking applications. The converter is designed for a 2:1 input range, either nominal 24 Volt (18VDC -36VDC) or nominal 48VDC (36VDC-75VDC). The converter is PCB mountable, the package has a form factor of 2” x2” x .4” and is six side shielded. The standard specifications include the Pi-input filter, excellent load regulation, remote ON/OFF capability, and short circuit protection. The isolation voltage meets the >1500VDC telecom requirements. SPECIFICATIONS: Nominal Input: 48VDC (36-75VDC) 24VDC (18-36VDC) Output Voltage: see Table 1 Output Power: 40W Efficiency: up to 90% Isolation Voltage: >1500VDC Operating Temperature: -25C to +71C Max.
