Ballast For Deuterium Lamps Heating Voltage 12.0V Heraeus Type PSD 185 OEM
The PSD 185 Deuterium Lamp Power Supply is a high
performance, low cost, compact and highly reliable
switching power supply. It is designed to operate on a 24
VDC input voltage. The supply has very low noise and drift
characteristics and uses a novel ignition circuit (US patent
No.5.530.319; EP No. 94 118 802.1) to ensure a soft and
reliable arc ignition, even when the lamp is hot. All Heraeus
30 W Deuterium Lamps with 2 V, 2.5 V, 10 V and 12 V
stabilized direct current heaters can be operated in the
optimum manner, to achieve maximum output stability and
lifetime. The PSD 185 is also suitable for most lamps made
by other manufacturers. The power supply is fully automatic,
from lamp ignition to steady-state operation. The small size
facilitates OEM integration of the power supply and lamp in a
compact system, for flexibility and reduced cost.
Automatic Lamp Operating Sequence
Automatic lamp ignition is started by connecting the external
24 VDC input voltage to the PSD 185 power supply. The
lamp heater is then pre-heated (warm-up cycle) for a period
of 10 seconds. After this, the strike voltage is applied and
when the lamp strikes, the heater voltage is automatically
adjusted to a preset level between 0 to 6 V depending on the
lamp type used. Should the lamp not strike immediately,
then further attempts are made automatically. The supply is
preset to run the lamp at an anode current of 300 mA. An
optional disable control is available by applying an external 5
VDC to the “disable” input.
