OUTPUT IMPEDANCE

<0.15n for the ±6-V outputs

and <0.3n for all other outputs at any frequency to 100

kHz.

TEMPERATURE COEFFICIENT

range of 0 to 60° C.

<0.02%/°C over a

TEMPERATURE PROTECTION

A thermal warning

switch will close when the supply temperature ap

proaches within 20° C of the safe operating value. A

thermal cutout switch disables the Power Supply when

the temperature exceeds the safe operating value.

NOISE AND RIPPLE <3 mV peak-to-peak for all six

outputs, as observed on a 50-MHz bandwidth oscillo

scope.

VOLTAGE ADJUSTMENTS ±2% minimum range, reset-

tablllty ±0.05% of Supply voltage.

CIRCUIT PROTECTION

Both sides of the Input line to

the power supply are fused. In addition, output current

foldback limiting to prevent damage to the Supply and

automatic recovery when the demand Is removed are

provided by electronic circuitry.

All six supplies are protected so that any one can be

shorted to any other one without resulting In permanent

damage.

Overvoltage protection Is provided on ±6 V so that these

outputs will not exceed 7.5 V maximum.

OUTPUT CONNECTOR

All power and control circuits

terminate In a connector, specified by TID-20893 (Rev 3),

which mates the Bin Interface connector, completing the

necessary control and Power Supply wiring.

DIMENSIONS

Conform to AEG drawing ND-515 and

paragraph L, page A-10, of TID-20893 (Rev 3).

RECOVERY TIME <100 fjs to return to within ±0.1% of

rated voltage for all six outputs for any change In Input

voltage and load current from 10% to 100% full load.

WEIGHT

Net 8.9 kg (20 lb); with 4001A(B) 13.6 kg (30 lb).

Shipping 12.3 kg (27 lb); with 4001A(B) 19.6 kg (43 lb).

3. INSTALLATION

The 402D Power Supply Is normally supplied factory-

connected to an EG&G ORTEG 4001A(B) Modular Sys

tem Bin. However, the Supply Is designed to TID-20893

(Rev) specifications and may be attached. In the space

provided, to any bin manufactured to TID-20893 (Rev)

specifications.

For attachment to other than an EG&G ORTEG 4001 A(B)

Bin, refer to the appropriate Instruction manual. The On-

Off switch and other controls necessary to operate the

supply are part of the Bin and are not furnished with the

Power Supply.

For attachment to the EG&G ORTEG 4001A(B) Bin the

following steps are advised:

1. Place the Bin on a table with the back part facing you.

Place the Power Supply In the proper mounting position,

leaving enough space between It and the Bin to attach

the Interface connector.

2. Mate the Interface connector, being careful to align

the polarizing pins. Fold and form all wiring close to the

connector edges to prevent any wires from being pinched

and producing a short circuit In succeeding steps.

3. Mount the Supply to the Bin by securely tightening

the four 10-32 screws, being careful not to pinch any

wires or to use undue force on any parts.

Unless otherwise specified, the 402D Is shipped with

transformer connections appropriate for operation on

nominal 117 or 230 V mains, according to the selection

made with the rear panel slide switch. To change the

connections for operation on 100 or 200 V power mains,

use the following steps:

1. Remove the top cover.

2. Move the wires from lug #3 of T1 to Its lug #2.

3. Move the wires from lug #6 of T1 to Its lug #5.

4. Replace the top cover.

5. Set the rear panel slide switch at 117 for 100 V opera

tion or at 230 for 200 V operation.
