Dimensions and
Weight
The 8630 and 8630B Series load is 22-1/8 inches long, exclusive of the
connector, 15-13/16 inches wide, and 15-15/16 inches high (562 x 402
x 405 mm). Its net weight, filled with 100 percent water as coolant, is
113 lb (51.3 kg) and the shipping weight is 125 lb (56.7 kg).
Power and Utility
Requirements
The 8630 and 8630B Series loads are offered in four standard forms
which differ in the ac input power requirements.
y
-115 for 115 V, 60 Hz, 9 Amp, single phase.
y
-230 for 230 V, 50 Hz, 4.5 Amp, single phase.
y
-115-5 for 115 V, 50 Hz, 9 Amp, single phase.
y -230-6 for 230 V, 60 Hz, 4.5 Amp, single phase.
Environmental
Requirements
The 8630 and 8630B Series loads are not intended for use outdoors
where they would be exposed to the elements. They should be used
indoors in a clean, dry, dust and vibration-free environment. The
ambient temperature range is determined by the coolant. For 100
percent water the range is +5°C to +45°C (+41°F to +113°F). For a
mixture of 65 percent water and 35 percent ethylene glycol the range
is -20°C to +35°C (-4°F to +95°F).
It is important that the room temperature remain within these limits
for proper operation of the unit, otherwise a derating of its load value
will be necessary. To avoid this derating, it may be necessary to
arrange for venting of the air flow from the load to the outside.
Consult Bird Electronic Corporation for more details.
