Series ATE power supplies are precision analog-controlled power supplies. They feature the high gain and zeroable offsets
to
precisely follow voltage signals or variable resistance controls with fast response into the mid audio range. The
voltage and current channels are equally controllable with automatic crossover between modes.
Series ATE is available in the following Models.
- Quarter-Rack (50 Watt) -- Size A Dimensions
- Quarter-Rack (100 Watt) -- Size B Dimensions
- Half-Rack (250 Watt) -- Size C Dimensions
- Three-Quarter Rack (500 Watt) -- Size D Dimensions
- Full-Rack (1000 Watt) -- Size E Dimensions
Panel-Mounted Controls/Indicators
Model ATE 325-0.8M (Analog meters)
Panel
-mounted analog meters allow monitoring of both channels.
Optionally, ATE models can be provided with digital displays.
To specify substitute the suffix "DM" for the suffix "M
" in the model number. For example: ATE 36-15DM
specifies digital displays. Local control of both channels is by panel-mounted 10-turn rheostats. Panel mounted LEDs
indicate which channel is in control (green is voltage, amber is current).This information is simultaneously delivered as an
optically isolated, TTL-compatible flag signal accessible through the rear connector ("0"
is voltage, "1" is current).
Model ATE 36-30DM (Digital meters)
Programmable Overvoltage Protector (Crowbar)
- activates an SCR short across the output to discharge the filter capacitor and protect the load;
- trips the a-c circuit breaker, and
- simultaneously lights a front panel indicator and generates an optically isolated flag to the rear connector.
Overvoltage trip-point can be manually set (with a front-panel level control); programmed with a 0-10V signal; or tracked to
the same signal that controls the output voltage (the margin is adjustable). Front panel "disarm" button allows the
set-point to be monitored without triggering the crowbar. Crowbar can be tripped by remotely generated pulse (through
optically isolated "trigger-in" port), allowing overvoltage protectors of several ATEs to be interconnected.
Two built-in uncommitted operational amplifiers...
...for scaling, summing, integrating, differentiating, inverting, or otherwise manipulating programming signals.
While the Series ATE power supplies are fixed gain amplifiers programmed by variable voltage input, the
uncommitted amplifiers can be used to emulate other programming modes used in other type of power supplies.
For example: resistance programming at any Ohms/Volt ratio desired, programming by conductance (inverse resistance), or by
various combinations of voltage, current, resistance, and conductance. The open loop gain of both amplifiers is a
minimum of 20,000 Volts per Volt.
Optional IEEE 488 listen-only control via optically isolated type SN digital to analog converters.
Full zeroing and calibration
Full zeroing and calibration facilities in both the voltage and the current control channels
for compatibility with the Kepco SN series digital to analog converters. The uncommitted amplifiers can also be
zeroed.
User selectable fast or slow modes of operation
In the slow mode, the ATE's dynamic stability and response are governed by a large output capacitor, and it is
therefore optimized for least excursion when voltage is stabilized and the dynamic load is a current.
Disconnecting the output capacitor puts the ATE into the fast mode, and optimizes it for the least excursion when the
current is stabilized and the dynamic load is a voltage.
In the slow mode the ATE is thus able to stabilize a
voltage against a rapidly changing load current; in the fast mode, it can stabilize a current against a
rapidly changing load voltage, and follow quickly changing program shifts.
Access to all control nodes
Access to all control nodes, via 50-terminal connector
which plugs into the user port in the rear, and can be reconfigured by simple rewiring to determine the ATE's
function. Rewiring the plug can make the ATE's a voltage supply, a self-powered, oversized op-amp, a servo amplifier,
or a feedback-responsive current or voltage stabilizer. The connector also contains the terminals for the uncommitted
amplifiers, the OVP circuit, the flags, and an analog (0-1V) output signal proportional to load current.
Rack Mounting
Rack mounting of the 1/4, 1/2 and 3/4 rack Series ATE is accomodated by the
RA 37 rack adapter.
