Technical Details – Components for Discharge Lamps
VS ignitors provide the following advantages:
• fully electronic construction
• compact design
• large nominal voltage range
• large output range
• low self-heating
• minimal power loss
• low noise
• long service life
• high electrical safety due to high-quality
components (e.g. approved capacitors)
• highly heat-resistant (max. permissible casing
temperature tc: 105 °C for superimposed ignitors
and 95 °C for pulse ignitors)
• highly fire-resistant potting compound
(certified according to EN 60926 and UL 94-V0)
• environmentally compatible potting compound
(waste key No. 57110)
Product range
Vossloh-Schwabe's product range covers superimposed and pulse ignitors in standard models and with
automatic cut-outs. Superimposed ignitors with automatic cut-outs are available with various cut-out times
and ignition voltage pulse mechanisms (A and D). In this respect, D-series ignitors featuring the intelligent
pulse-pause mode (IPP) are the best solution in terms of ignition reliability and switching off defective
lamps.
Electronic ignitors with integrated cut-outs capture data on ignition behaviour during the ignition process.
These data, e.g. regarding ignition frequency or failure, serve to identify ageing lamps and to ensure the
ignition process is reliably switched off after a defined period of time at the end of the lamp's service life
or in the event of defective lamps. This reduces the negative consequences associated with defective
lamps.
Superimposed and Pulse Ignitors
with Automatic Cut-out
Ignitors with IPP technology and extended cut-out – D series
After connection to mains voltage, D series ignitors generate ignition voltage pulses that are controlled and
if necessary switched off by the ignitor in accordance with the lamp's operating state, lamp recognition
and the safe burning time. If the safe burning time is not attained after three consecutive ignition attempts,
pulse generation will cease.
Appropriately programmed microprocessors enable these performance features
of ignitors with IPP technology (Intelligent Pulse-Pause Mode) and extended cut-outs.
