Solutions for UV Systems Electronic Ballasts for Low Pressure Lamps and Amalgam Lamps ! wide variety of Ballasts : Electronic Ballasts are directly interchangeable with magnetic bal- Ballasts for one, two or four lamp lasts. They operate with most of available uv-lamps. Long term operation usage has demonstrated the reliability of Electronic Ballasts . Ballasts with integrated hour counter Electronic Ballasts that operate two or four lamps at once, are allo- and uv-monitor wing the use of a single ballast in Systems with several lamps.

5 This power range from 10W to 600W reduces installation and field wiring costs. Other advantages are reduced weight, quieter operation and reduced lamp flicker. lamp current from 100mA to 6A. supply voltage 115V AC, 230V AC, Electronic Ballasts basically consist of the following functional units: 12V DC and 24V DC filter - EMI-filter to attenuate conducted RF noise ! instantaneous start without flicker for rectifier long lamp life time PFC (power factor correction) - provides sinusoidal line ! equipped with power factor correction - current CE-conform charging capacitor ! lamp faults are indicated by a potential frequency controller (for high-frequency conversion). free relay contact (alarm trigger); LED s power stage display the current mode of operation resonant tank ! up to 30% energy saving compared to and also conventional Ballasts fault logic (open-circuit / short-circuit protection).

The Electronic ballast became the standard in the lighting industry. It leads to significant energy and money savings in nearly every appli- cation. The lamp operation is flicker free and the ballast produces vir- tually no noise or hum. The incoming 50/60 Hz power (115 or 230 volts) is converted to high- frequency AC (usually 20 to 40 kHz). This leads to a constant gas discharge compared to conventional Ballasts and prevents cathode flicker. Electronic Ballasts are more efficient than magnetic Ballasts in con- verting input power to the proper lamp power.

7 The operation of uv- lamps at higher frequencies reduces end losses, resulting in an overall lamp- ballast system efficacy increase of 15% to 20%. 09/2006 -2- ZED - Ziegler Electronic Devices GmbH - Ilmenauer Strasse 9 - D 987O4 Oehrenstock/Germany Phone: ++49 (O) 3677 2O 59 259 - Fax: ++49 (O) 3677 2O 59 26O - url: - E-Mail: ZED - ZIEGLER Electronic DEVICES GMBH. Solutions for UV Systems Electronic Ballasts for Low Pressure Lamps and Amalgam Lamps Operation Modes of Electronic Ballasts Instant, rapid or preheat? There are three modes of operation of the lamps: ! rapid start ! preheat start (-PH). ! instant start (-IS). Rapid start Ballasts These Ballasts are used for lamps with four-pin connection. During startup a short high current pulse is sent to the lamp fila- ment. This reduces unwanted sputtering of emissive material at the electrodes.

8 Compared to instant start Ballasts , lamps tend to live longer with rapid start Ballasts , in case of many on-off cycles. So rapid start Ballasts are recommended when the switching cycle for the lamps is more than three times per day. During operation current is flowing through the lamps filament. The electrodes of the lamps must fit with this ballast type. Preheat start Ballasts (-PH). These Ballasts are also used for lamps with four-pin connection. Preheat Ballasts provide a preheat current at the filaments that allows the electrode to heat up before ignition. During the preheat interval, voltage across the lamp drops to a level that reduces the unwanted glow current. The ballast applies sufficient voltage to the electrodes, long enough for the electrode to reach the emission temperature to prevent lamp ignition before the electrodes are heated up.

9 After the end of programmed time for preheating, the ballast app- lies a voltage across the lamp to ignite it with minimal loss of emis- sive material. This optimizes the lifetime of the lamp. These Ballasts are intended for applications with many switch on cycles. We offer preheat start Ballasts on request for lamps with a minimum power of 200W (see the PH in the type name). Instant start Ballasts (-IS). These Ballasts are used for lamps with two-pin connection (see the IS in the type name). Instant start Ballasts ignite lamps by applying high voltage across the lamp during setup. The high voltage typically ignites the lamp immediatly. These Ballasts do not heat the electrodes. Instant start Ballasts should be used for continously lamp operation with less than three switches per day. The advantage is the lower wiring effort compared to four-pin connection.
