其他信息

Some of the performance features of the LC2000 Series Telephone Line Interface Resistor Networks are:

• Lightning Transient Handling while maintaining Precision Ratio Tolerance.

• Quick Fail-Safe Performance when exposed to Cold Start Voltages of 120 VAC, 240 VAC, or 600 VRMS AC. Protects Telephone System Wiring from damage or ignition.

• Available with optional Spring Thermal Cutoff Protection mounted on the resistor network substrate. When excessive low voltage power cross causes excessive heating in the Resistor Network, the Spring Thermal Cutoff opens the circuit and protects the circuit board from heat damage or ignition.

• Available with optional Thermistor Temperature Sensing Element for controlling a relay circuit which disconnects the excessive low voltage overload, protecting the circuit board from heat damage.

• Resistance: 24Ω Pair, 30Ω Pair, 40Ω Pair, 50Ω Pair, 100Ω Pair, 200Ω Pair, or Custom Values.

• Precision Ratio Tolerance of 0.25%, 0.5%, or 1.0%

• Operating Temperature: -40°C to +85°C.
