Silvertel’s Power and Telephony Product Overviews

Battery Charger modules

Silver Telecom’s battery charger modules are designed for reducing power consumption and maximising 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.

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.

Available in single in line (SIL), dual in line (DIL) and surface mount (SMT) packages.

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.

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.

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.

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.
