| T8 Dimmable Electronic
ballast BT8-D 18W/30W//36W/58W/2x18w/2x30W/2x36W/2x58W |
| Definition |
| Compact,lightweight high-frequency electronic standard ballasts
for T8 fluorescent lamps |
| Description |
| - programmed start:ficker-free warm start,ideal for areas
with high switching frequency. |
| - 50% longer lamp life than with conventional ballasts |
| - Up to 25% reduction in energy consumption at constant luminous
flux compared with |
| conventional gear. |
| - Constant light independent of mains voltage fluctustions |
| - Unit is protected against excessive mains voltages and incorrect
connections. |
| - Automatic stop circuit is activated within five seconds
in case of lamp failure(safety |
| stop): once the lamp has been replaced, the ballast resets
autonatically. |
| - Equipped with terminations suitable for automatic wiring
machines. |
| - Dimmable mode:potentiometer,DC voltage,Thyristor. |
