G Series AC Power Systems-1

Environmental Characteristics Efficiency (EFF) Varies with type of load attached to the power source as follows: EFF = 70–90% with predominantly power supply type loads. EFF = 70% at maximum (125 V) output. EFF = 65% at nominal (120 V) output. EFF = 60% at low line (105 V) output. Ambient Temperature 0 to 55°C Operating. –40° to 85°C Nonoperating. Humidity 0–95% relative humidity, noncondensating. Cooling Self contained fans provide forced air cooling. All air inlets are filtered. Filters are replaceable and reusable. Heat Dissipation If system location is to be air conditioned, allow 800 BTU/hour per kVA for a typical electronic load (higher for mixed or linear loads). NOTE: One ton of cooling = 12,000 BTU/hour. Ventilation required to maintain less than a 10°C rise in the ambient temperature for a typical electronic load: 390-G – approximately 600 CFM. Input/Output Service Connections Input and output connections are made via a heavy duty terminal block mounted inside NEMA-approved junction boxes that are located on the lower rear panel of the mainframe. Allow an additional 3.25˝ to overall depth for junction box clearance, or 5.25˝ when “T” output option is specified. Mechanical Specifications Dimensions A. Height w/caster base B. Height w/forklift base C. Width D. Depth Each G Series mainframe is provided on a caster base with leveling feet for ease of installation. Forklift or shock mount base is optionally available.
