<p>+/- 36-72VDC IN, 24VDC OUT 30W High Power DC to DC Converter/PoE inserter. 10/100Mb.</p><br><p>They have an integrated 10/100Mb Passive PoE injector to apply the regulated 24VDC to the CAT5 Ethernet cable. The input voltage must be between 36VDC and 72VDC.</p><br><p>They include an integrated POE inserter to apply the DC voltage to the CAT5 cable on Pins 4,5 (V+) and Pins 7,8 (V-).</p><br><p>They have 2 isolated inputs to handle two power sources like a primary and backup source for uninterrupted failsafe operation. The input and output power are isolated so they can be used to convert a negative voltage to a positive voltage.</p><br><p>Because of their wide input voltage and regulated output, they can also be used to stabilize a voltage output. Example; a voltage source is a long distance from the equipment with wide voltage fluctuations seen at the equipment.</p><br><p><span>Dimensions: 85 x 76 x 36mm (3.4 x 3 x 1.4in)</span><br /><span>Weight: 134g (4.7oz)</span></p><br><p><strong>Features</strong></p><br><ul class="bullet"><br><li>Input Voltage 24VDC or 48VDC</li><br><li>Passive POE Output voltage 24VDC or 56VDC</li><br><li>IEEE802.3at Model Available</li><br><li>High Power up to 35W</li><br><li>Dual DC Inputs for connecting 2 power sources</li><br><li>Integrated POE Inserter</li><br><li>Low self consumption power</li><br><li>Short Circuit, Over Current and Reverse/Over Voltage Protection</li><br><li>High Temperature Operation</li><br></ul><br><p><strong>Applications</strong></p><br><ul class="bullet"><br><li>24V and 48V Battery Systems</li><br><li>Wireless Access Points and Client Devices</li><br><li>IP Phone and Security Camera Systems</li><br></ul>
