Phihong, the global provider of low cost power supplies, has begun mass production of its Power-over-Ethernet single port injector, which is now widely available and in stock at distributors. Designated the PSA16U switching power supply, the device is one of the only single port injectors to fully comply with the new IEEE802.3af international standard, and is ideal for applications such as wireless access points, security cameras and IP telephones.
“There is a tremendous amount of interest in making the move to Power-over-Ethernet technology, but until now it has often been too expensive and the products inaccessible,” said Keith Hopwood, Vice President of Marketing for Phihong USA. “With the PSA16U now widely available through distiribution, Phihong is offering a cost effective product that directly delivers the significant cost savings associated with implementing a PoE system for wireless access points.”
PoE technology is an innovative solution to problems involving AC power and the placement of power outlets. PoE allows both power and data to be carried over an Ethernet cable. While installing local power outlets in a warehouse, store or office can cost hundreds of dollars and cause delays due to scheduling for an electrician, moving or installing an Ethernet cable doesn't carry any of these limitations.
AC input voltage range for the single port injector is 90VAC to 264VAC with voltage range from 100VAC to 240VAC and AC input frequency from 47Hz to 63Hz. Maximum output load current is 0.35A and O/P voltage is +48VDC. The device offers total output power of 15.4W with fully compliant detection, connection, disconnection and fault protection per the IEEE standard.
The adapter features 3 LEDs that indicate power, connection and faults to ease installation and set-up. Safety approvals for the PSA-16U include cUL, TUV and CE double insulated class 2. Approvals for EMI are EN55022 Class B, FCC part 15 Class B. Phihong is an expert at international safety agency approvals and can offer almost any international safety or EMC compliance standard.
Typical pricing for Phihong's single port injector is $14.95 each in OEM quantities. Parts are available immediately.
Phihong is a supplier of power solutions to networking and personal electronic OEMs supplying custom power supplies from 10-1.5kW, power adapters and PoE injection solutions. With global sales for 2005 expected to exceed $350 million, Phihong has engineering and manufacturing facilities in North and South America, Taiwan and mainland China.
