The Burk TS-1 provides transient voltage surge suppression for equipment connected to a dial telephone line with standard RJ-13 or RJ-11 connectors. The high quality die cast aluminum enclosure houses a passive, three-stage protection device designed to conduct destructive energy safely to ground. Both RJ connections are protected, while allowing the normal ring voltage and voice or data to pass unimpeded.The TS-1 can also protect studio or transmitter audio equipment connected to a two-pair dedicated stereo telco circuit.Burk TS-1 Features:Cost-effective voltage surge protection for equipment connected to standard telephone linesFast response timeClamps directly to ground strap for best low-impedance path to groundProtection against repeated surges allows trouble-free operationLow clamping voltage provides maximum protection while still allowing ring voltages, data and voice to pass unimpededBurk TS-1 Specifications:Response Time: 5 nanosecondsClamping Voltage: 200VMaximum Current Surge: 10,000AMaximum Repetitive Surge Current: 2,000AMaximum Series Current: 1ASeries Impedance: 24 ohmsDimensions: 1.75″ (4.45cm) H 3.25″ (8.26cm) W 5.50″ (13.97cm) DOperating Temperature: 0 to 85 COperating Humidity: 5% to 90% non-condensingOperating Altitude: 10,000 feet (3048m)
