VTL110

The VTL110 is a kind of low cost neon vactrol. It adopts a 70 VDC neon lamp. The vactrol is well suited for telephone ring detectors and other high volume applications where the supply voltage is limited for the guaranteed low voltage breakdown.

What comes next is the absolute maximum ratings of VTL110: (1)storage temperature: -30 to 65 ; (2)operating temperature: -30 to 65; (3)cell power: 175 mW and derate at 3.5 mW/ above 25; (4)cell voltage: 150 VDC; (5)minimum isolation voltage @ 70% rel.humidity: 3000 Vpk for 1 min; (6)neon lamp breakdown voltage: 70 VDC; (7)neon lamp sustaining voltage: 47 VDC; (8)recommended minimum supply voltage: 50 VAC.

The following is the electro-optical characteristics @ 25 (external limiting resistor required) of VTL110: (1)lamp input voltage: 50 VAC; (2)lamp input limit resistor: 33 k; (3)dark adapted: 1.0 k typ; (4)off resistance @ 10 sec: 1.0 M min; (5)turn-on to 63% of final row: 3 ms typ; (6)turn-off (decay) to 3k: 5 ms typ.
