Ballasts for operating UVH lamps

Ballasts for operating UVH lamps.

A ballast that controls the operation of the lamp at the desired power is required for using a UVH lamp. Combinations of chokes and a starter can be used for lamps operating at a power of up to 5 kW.

In the power range of 5 kW up to approximately 8 kW, combinations of an autotransformer and chokes are used while leakage-field transformers are preferred from a power level of 8 kW upwards. Currently our most powerful lamp provides 60 kW of energy !

Ballasts can be designed for single-level or for multi-level operation. Continuously variable versions are also available without problems in all power ranges of mercury vapour lamps. Alternatively, continuously variable electronic ballasts can be used in the power ranges from 1.2 to 34 kW and with a lamp length of up to 125 cm, in special cases also somewhat longer.

With conventional ballasts, stand-by operation at 35 - 40% of the maximum power output is possible if it is required by the respective process. If electronic ballasts are used, significantly lower standby power levels down to approx. 10% can be realised. Operation in stand-by mode almost always requires a reduction of the lamp cooling.
