 THE FEATURES
of
BALLAST  XENLIGHT

Ballast Features:

• +      Low Electro Magnetic Interferences (mostly significant for Automotive Industry, Aviation, Medical devices, etc.). No EMI shielding required, we use plastic housing.

• +  Safety - No electric shock risk (patented, no DC phase, High frequency).

• +  Dimmable ballast with bidirectional remote control line or control unit which makes the ballast 100% ready for the automotive market by using the car computer to control it.

• +  High efficiency - operates at very low temperatures (ΔT=21°C) over wide range of operating conditions.

• +  Operates D1S or D2S bulbs 12V/24V 21W/35W/50W combinations includes D2S lamp holder with up to 2 meters of cable.

• +  One of the smallest ballast available on the market.

• +  4 granted patents, 2 pending patents.

• +  Active false input polarity protection.

• +  Remote power dimming selection for headlight range variation.

• +  Short output protection.

• +  Open output protection.

• +  Input over voltage switches off with automatic restart.

• +  Input under voltage shut down, self locking.

• +  Negative lamp supply voltage in respect of car ground.

• +  Fast restart cycles.

• +  Smooth lamp current curve.

• +  Smart light run up control.

• +  Can be operated from car cigarette lighter with 10 meter cable ( high efficiency and limited inrush currents)

DC-DC converter features:

• -  The DC-DC converter type combines the advantages of a
     blocking and a direct DC-DC converter (Patented)

• -  Mode of operation adapts automatically to momentary
     requirements

• -  Variable pulse width and variable frequency, up to
                             f max = 250 kHz

• -  Excellent efficiency and excellent EMI performances.

Inverter features:

• +  Based on low RDS on standard N-channel power MOSFETs.

• +  Minimum cross conduction losses.

• +  Insulated gate control keeps driving power low by using the gate control pulses also as gate charge power pulses keeping gate open by its own static memory function.

Control features:

• -  Real time analogue multiplication uses the ohms operating area of a single bipolar transistor to keep output wattage constant - Patented DE-196 27 989 A1.

• -   Run up power is reduced automatically when bulb is hot to avoid over powering of the bulb.

• -  Safety circuit monitors lamp operation and shuts down ballast operation completely.

• -  Lamp power is selected to the lower power level automatically at low input voltage condition.

• -  Remote line monitors bulb operation and gives a positive feedback signal to an external micro processor, enabling extended light control features for the total system.
