Silvertel's Power and Telephony Product Overviews

  • Battery Charger modules - Silver Telecom's battery charger modules are designed for reducing power consumption and maximizing rechargeable battery life. The modules have a wide input range and a high efficiency DC to DC converter. The charging voltage is controlled with a high accuracy and can be varied with temperature. The module also reports on the battery condition to eliminate unnecessary battery changes or unexpected battery failures. Different modules to cover Sealed Lead Acid (SLA) and Lithium Ion battery
  • Power over Ethernet - POE module 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.
  • SLIC module - 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.
  • PSTN module - PSTN interfaces, 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 Pt.68, UL60950, AS NZ3260 and AS ACIF S043.

 

60W PoE made easy: Silvertel launch IEEE802.3bt  Power over Ethernet Module for the Powered Device

Silvertel announces the launch of the IEEE 802.3bt compliant Ag5810 PD (Powered Device) module, to cement their position as the leader in embedded Power over Ethernet (PoE) solutions.

Aimed at developers of Ethernet equipment requiring up to 60W of power, such as LED lighting, PTZ cameras, WiMAX access points, door entry systems, digital signage and thin client terminals, Ag5810 provides a low cost drop-in IEEE802.3bt solution.

Designed and manufactured in the UK, this latest product from Silvertel rounds off their IEEE802.3bt range which includes the Ag6800: a 97W PSE (Power Sourcing Equipment) module; and the Ag5800: a PD module capable of delivering 85W.

Ag5810 is a Type 4 - Class 7 PD, which provides 60W of power by displaying the correct class pulses to a IEEE802.3bt PSE.  A complete high efficiency DC-DC converter is included, that generates a nominal 12V or 24V output, which can be programmed down to 11V, or up to 30V, this is especially useful for applications requiring the inclusion of battery chargers.

Additional features include 1500V isolation (input to output), overload, short-circuit and thermal protection.

Requiring just a few low cost external components, Silvertel has provided another product which is low cost, easy to use, and occupies a minimum of PCB real estate.  Ag5810 evaluation boards are also available, as well as a range of application notes, backed by Silvertel’s class-leading technical support team.

Ag5810 supplements Silvertel's extensive offering of Power over Ethernet products for both the PD and PSE.  Silvertel also offers a comprehensive range of IEEE802.3af and IEEE802.3at modules, with a smart lighting PoE module coming soon.
