Description
The ADH– 2A COM Automatic Dehydrator supplies low pressure -40°F (-40°C) maximum dew point air to keep waveguide and coax dry. The standard pressure is 0.5 psig (34.5 mbar) with 3 psig (207 mbar) and 6 psig (414 mbar) options. Standard features include automatic regeneration, alarm and low pressure relays and an RS– 422/RS– 485 communications interface thus making unattended operation practical.
The ADH– 2A COM uses LED displays and indicators to provide a wide viewing angle and good visibility under low-light conditions. Displayed information includes status, operating and fault diagnosis data along with air pump operating time.
The ADH– 2A COM operates with exceptionally low noise and vibration levels. The dehydrator uses aluminum oxide desiccant for high efficiency. The humidity sensor causes regeneration based upon current dew point rather than at fixed time intervals for additional energy savings and long desiccant life. Dual micro-controllers and solid state circuitry insure reliability. Two ADH-2A COM dehydrators can be connected in master/slave configuration to provide redundancy and increase reliability.
The ADH– 2A COM requires only 5-1/4" of panel space. An internal evaporator eliminates the need for a water drain. The dehydrator operates from 120/230 volts 50/60 Hz or optionally, 24 VDC or 48 VDC. A user-set jumper selects the display of either SI or English units.
The ADH– 2A COM consumes a maximum of 150 watts during regeneration and approximately 60 watts otherwise. Thus, this products creates an exceptionally low heat load for an automatic dehydrator.
