Electrical Power
The EQ-99-FC requires 12VDC at 11.7A minimum (140W rating). Power consumption is
approximately 100W during normal operation.
Power can be provided using the optional PS00018 12VDC power supply. Alternatively,
power can be provided directly via a customer provided 12VDC power supply. The connector
on the EQ-99 is a latching connector. Once fully inserted, the connector will not release unless
the body of the connector is pulled first. This protects from accidental removal of power if the
power cable is pulled. Connect to a 12VDC source as follows:
Connector Kycon
KPPX-4P
Pins 3 & 4
+12VDC
Pins 1 & 2
12VDC return
Purge Gas
Purge gas is optional but is recommended for best performance. With no purge, ozone will
form from atmospheric oxygen and attenuate the light output in the 220 – 280nm band. In
addition, atmospheric oxygen and water vapor will attenuate the output below 200nm.
If required, connect a source of nitrogen purge gas to the port on the Lamp House. The
fitting is a push-to-connect type, sized for 4 mm tubing.
Clean and dry nitrogen from either a dewar or research-grade N
2
bottle is recommended. Do
not use any other purge gas.
Grade 6 or better gas purity is recommended to maintain
cleanliness of the optics, and the gas should be filtered to < 5um. Supply pressure should be
20 psig (0.14 MPa). With a 20 psig inlet pressure, the EQ-99-FC will consume approximately 1
slm of flow.
There is no return fitting for the purge nitrogen. The purge flow normally escapes within the
Lamp House enclosure, and then to atmosphere.
