wide adjust output
Rack Mounting
LINEAR REGULATED
AC-DC
(fixed & adjustable current limiting)
Similar to the rack mounting power supplies
listed on pages 40 and 41, but with broadened
output voltage ranges. All models may be
programmed through their voltage ranges by means
of external resistance. Models with adjustable current
limiting have a constant-voltage/constant-current
crossover characteristic, and so may be used as
constant current sources.
SPECIFICATIONS
Input Voltage: 105-125 VAC,
50-400 Hz, single phase.
Regulation, Ripple (in constant voltage mode):
Line Regulation: ±0.005% or 2 mV, whichever is greater.
Load Regulation: ±0.005% or 2 mV, whichever is greater.
Ripple: 0.25 mV rms.
Regulation, Ripple (in constant current mode):
Line Regulation: ±0.1% or 2 mA.
Load Regulation: ±0.2% or 5 mA.
Ripple: 0.1% rms.
Remote Voltage Sensing: Provision for sensing the
output voltage across the load, to compensate voltage
drops in output wiring, is a standard feature.
Remote Voltage Programming: The output voltage may
be controlled by means of external resistance connected
in series with the – S lead.
Voltage Programming Coefficient: See table.
Calibration tolerance, ± 2%.
Current Limiting/Programming: Models with fixed
current limiting have a rolloff characteristic with automatic
recovery. All others have current limiting with a
constant-voltage/constant-current crossover characteristic.
Polarity: Output is floating; either positive or negative
terminal may be grounded or floated up to 300 volts
above ground.
Controls: Coarse and fine voltage adjustments, and the
current limit adjustment, are located at the rear of the
assembly.
Temperature Coefficient (in constant voltage mode):
0.02%/°C (Typical).
Ambient Operating Temperature: – 20 to +71°C.
Storage Temperature: – 55 to +85°C.
Dimensions and Connections: See page 40.

OPTIONS
Overvoltage
overvoltage protection circuit, set approximately 20%
above the maximum output voltage rating of the supply, is
available on all models. To order, add prefix “V” to the
model number, and increase standard price as follows:
Remote Current Limiting Adjustment: All models
having numbers beginning with the letter P have a built in
current limit control. Provision for control of the current
limit setting by adjustment of an external resistance is
available as an option. To order, add the prefix letter “E”
to the model number, and add $25.00 to the standard
price.
The current limit setting is inversely related to resistance.
Use a 200 ohm,
Ammeter: Add suffix “A” to model number and $45.00 to price.
Voltmeter: Add suffix “F” to model number and $45.00 to price.
Handles: Add suffix “H” to model number and $30.00 to price.
Terminal Strip Cover: Clips on. To order, add suffix “M” to
model number and $5.00 to price.
Front Panel Controls: For voltage controls (coarse and
fine) mounted on the front panel, instead of the standard
screwdriver-slot adjustments at the rear, add suffix “P” to
the model number and $25.00 to price. For a current limit
control mounted on the front panel, add suffix “Y” to the
model number and $15.00 to price.
230 Volt Input: For operation on inputs of 210 to 250 VAC,
50-400 Hz. Add suffix “–230” to model number and $40.00
to price. The “–230” option requires two additional days.
