LOCATION, MOUNTING, AND VENTILATION
The power supply was designed for rack-mounted or bench top applications.
RACK MOUNTING INTALLATION:
1- Use the integral rack-mount ears at both sides of the front panel to install the power supply in a
rack-mount application.
2- Provide adequate support for the rear of the instrument without obstructing the ventilation inlets
on the sides of the unit. Use a support bar at the bottom or rear of the unit, this item is not
provided by AMREL. The support bar can be purchased from the enclosure manufacture, please
follow the rack-mount manufacturer’s instructions for proper installation.
Mounted from the left front panel
NOTE:
Must install two angle supports under the unit
(NOT INCLUDED)
Mounted from the right front panel
VENTILATION:
Whether you place the power supply in a rack or on a bench, allow cooling air to reach the ventilation inlets
on the sides of the instrument and allow 4 in. (101.6mm) of unrestricted air space at the rear of the unit for
the fan exhaust. Any ventilation space at the top and bottom of the supply will further lower internal
operating temperatures.
