A -- Power Over Ethernet PD moduel solution  

 

Silver Telecom Ltd has designed and developed several Power of Ethernet (PoE) module ranges to suite different applications. Our PoE modules require minimal external components and all have built-in signature recognition and class programming which complies to the IEEE802.3af standard. For flexibility most of our PoE modules are available with different output voltages, all have output voltage offset adjustment, short circuit protection and thermal protection. 

 

These PoE modules provide a cost effective and easy to use solution for applications such as Voice over Internet Protocol phones (VoIP phones), webcams, wireless access points, security cameras, security equipment and door entry systems. 

 

A-1 : IEEE 802.3af PD modules  

 

a. Ag8000 series : Ag80xx , Ag81xx & Ag82xx ==> Low Cost & Non-Isolated Series !!  

 

 

 

       

 

 

b. Ag9000 series : Ag9xxx , Ag92xx & Ag94xx (Isolated Series)   

 

 

         

 

c. Ag9000 series : Ag9600 & 93xx/Ag95xx (Isolated Series for IP Surveillance application)       

 

 

 

  

 

A-2 : IEEE 802.3at PD modules

 

Ag5000 & Ag5100 series :  The Ag5x00 is a PoE+ module that can deliver up to 30 Watts of output power. This is ideal for   applications such as IP Telephones, WiMAX access points, PTZ cameras and remote computer terminals. The input Signature complies with both the IEEE802.3af and IEEE802.3at specifications and it is designed to meet the safety isolation requirements of IEEE802.3at.   

 

Note : Ag5000 did not compliant the IEEE802.3at 

 

 

 

 

B -- Telephone line interface solution

 

B-1 : SLIC interface , Ag1170/Ag1171

 

Silver Telecom's Subscriber Line Interface Circuit (SLIC) modules can be used for analog line interface applications, enabling signals to be transmitted and received from the telephone line, feed power to the line and monitors the line condition.

 

Our SLIC modules are designed to provide a small, easy to use and low cost solution for ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI) Wireless Local Loop (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and Small Office Home Office (SOHO) applications. 

 

Available in single in line (SIL) or dual in line (DIL) packages. 

 

 

 

 

B-2 : PSTN interface : Ag2120/Ag2130

 

PSTN nterfaces, also known as Trunk Interfaces, Foreign eXchange Office (FXO) circuit, Data Access Arrangements (DAA) and Central Office Interface Circuit (COIC). Silver Telecom PSTN modules that are suitable for a wide range of applications and meet the requirements of CTR21, FCC Part 68, UL60950, AS NZ3260 and AS ACIF S043.  

 

Providing programmable d.c. mask, line and network impedance give our PSTN modules the flexibility to be used in any market. On-Hook reception allows our modules to support Caller Line ID and by using transformer isolation this provides high common-mode rejection for use in ungrounded systems.  

 

Available in single in line (SIL) or dual in line (DIL) packages.

 

 

 

 

 

C -- SLA Battery Charge 

 

Ag102 :  Intelligent Sealed Lead Acid Battery Charger Module

 

 

The Ag102 is a micro-processor based intelligent, cost effective, sealed lead acid (SLA) battery charging module. It uses digital technology to optimise the charging of standard, 12V sealed lead acid batteries between 1.2Ah and 7Ah capacity. Using various intelligent charging techniques the Ag102 technology will maximise the manufacturers specified battery lifetime.

 

The Ag102 has a very wide input range of 9V to 36V DC. This gives extensive flexibility and means the system and charger requires just one, lower cost, power supply. When used in conjunction with Silver Telecom Power over Ethernet (PoE) module, the Ag102 can charge SLA batteries from power obtained over an Ethernet cable.
