The ORTEC 401A Modular System Bin provides mount- ing space for 12 standard module widths of the 8%-in.-high type. The 12 corresponding module connectors are provided, with necessary wiring for distribution of all of the standard power supply voltages. The ORTEC 401B Bin is identical except that the standard power supply voltages are dis- tributed to the module connectors through bus bars instead of wires. These power distribution circuits terminate in the standard connector prescribed by TID-20893 (Rev.) for connection to the power supply. A small control panel, not occupying any of the available module space, is located at the right side of the Bin, providing control switch test points, a control switch, and indicator lamps for the power supply. Further description of the 401A(B) Bin is given in the remaining sections of this manual.
MECHANICAL TOLERANCES
In accordance with TID- 20893 (Rev.) provide for interchangeability
of all standard modules.
PANEL DIMENSIONS
Standard Relay Rack, 8 3/4 in. high, 19 in. wide.
DEPTH BEHIND PANEL
Without Power Supply, 10,5 in. (26.6 cm); with 402A Power Supply,
16.0 in. (40.6 cm); with 402H Power Supply, 18.0 in. (45.7 cm).
MODULE CONNECTORS
12 each connectors as specified by TID-20893 (Rev.).
INSTALLED WIRING
All connectors of the 401A are wired in parallel for +6 V, -6 V, +12
V, -12 V, +24 V, -24 V, high-quality power return and 115 V ac, in
accordance with TID-20893 (Rev.) pin assignments, with interface
connector furnished for connection to power supply as required by
TID-20893 (Rev.). The 401B is equipped with laminated bus bars on the
+6 V, -6 V, +12 V, -12 V, +24 V, -24 V (AWG #14 equivalent) and for
the power ground return (AWG #10 equivalent).
CONSTRUCTION
Extruded aluminum side members. Die-cast aluminum top and bottom
members containing module guides and cadmium-plated steel rear
connector plate, Iridite or cadmium finished, with convenience
handles on front panel mounting members.
WEIGHT
28 lb net with 402A Power Supply; shipping weight 35 lb; 36 lb net
with 402H Power Supply; shipping weight 43 lb.
ON-OFF
Switch interrupts both sides of the input power line.
POWER
Pilot lamp indicates that ac input power is being supplied to the
power transformer primary. Either a blown fuse or a temperature
cutout will extinguish this lamp.
TEMP
Warning pilot lamp is illuminated if the Power Supply temperature
rises to within ~20degC of the maximum safe operating temperature.
When the maximum safe temperature is reached, an internal cutout in
the Power Supply removes power and neither lamp will be
illuminated.
TEST JACKS
Located on the panel allow convenient checking of the Power Supply
voltages from the front panel without disassembly of the supply
The available current at each voltage is dependent on the Power Supply. Since the requirements of TID-20893 (Rev.) have been changed from time to time, the actual capability of any given power supply will depend on its date of manufacture. The instruction manual for the particular power supply in use should be consulted.
The power requirements of individual modules are stated on their front panels. The user should verify that the Power Supply capability is not exceeded in any given system in one bin. Note that a system composed entirely of ORTEC modules will not require this verification, since each ORTEC module uses no more power than its pro- portional share based on panel space occupancy in the Bin.
