30981 TGA200A Power Module


The 30981 is a power module included with the TGA200A that provides 12 Vdc and 24 Vdc to the TGA200A. The 12 Vdc is used to power the electronics of the trace-gas analyzer, while the 24 Vdc is used to power the heaters and fans that regulate the TGA enclosure temperature. A pair of 15 ft power cables with keyed connectors are included with the module. Corresponding keyed connectors are found inside the module enclosure and in the TGA200A enclosure. AC power input is required, and the appropriate input cable type should be specified at the time of order. The type of mounting hardware for the module is also specified at the time of order.

Unlike previous trace-gas analyzer models that housed the power supplies inside the analyzer enclosure, this separate module helps to isolate RF noise and facilitates easy replacement of parts.
