Informationen:
                                    The Model 4265A is a programmable, bipolar dc voltage
source. Output voltage is from 0 to 65.532 vdc in two
ranges; 16 and 65 vdc. Programming resolution using the
internal reference voltage is 1 mv on the 16 volt range and
4 mv on the 65 volt range. Output accuracy is ±.01% of the
programmed level on both voltage ranges. After a 100 /sec
settling time, a READY/NOT READY FLAG indicates that the
output has settled to ±.01% of the programmed increment for
a resistive load. The output current is rated at ±1 ampere
maximum and is limited to approximately ±1.1 ampere in the
event of an overload or short circuit. The sink current
(milliamps) is rated at 1000-10 Eout maximum. A Programmable
Current Limiter (Option -06) is available to allow
programming the maximum output current to a lower level. A
current limit flag indicates when a sink or source current
overload exists with or without the -06 Option.
1-3. Programming requirements are compatible with DTL or TTL
logic levels. Contact or relay closures can also be used.
The voltage source is programmed on the low range using
straight binary coding. The high range is also programmed in
the same manner, but the actual output is four times the
programmed level. Two's complement coding is required for
negative outputs when the Isolated Control Logic (—01
Option) is installed. All programming inputs
and flag outputs are available through a 50 pin Amphenol,
Blue Ribbon connector located on the rear panel. A +5 vdc
output is also available at this connector and is used to
provide power for external programming circuitry. Negative
logic is employed for programming. The logic levelsi are as
follows:
Logic “0” = +2.0 vdc to +5.0 vdc or open circuit
Logic “1” = 0 to +0.4 vdc or short circuit to LOGIC GRD.
1-4, Three options are available to provide tailoring of the
power supply to fit application requirements. These options
are identified by numeric designations -03, -06, and -09. A
description of each option is provided in Table 1-1. These
options may be installed at the factory when the instrument
is ordered or in the field at a later time.
1-5. Physically, the power source is completely solid state.
Plug in printed circuit boards, with easy to reach test
points and adjustments, are used for ease in servicing. The
unit is forced air cooled. This results in lower component
temperatures and thus higher reliability than would normally
be obtained in a source of this power capability. The
chassis is designed for bench top use, or it can be
installed in a standard equipment rack by using the
Accessory Rack Mounting Fixtures.
