MR Series

300 Watt

Regulated

High Voltage

DC Modules

Models from

0-1 kV DC

through

0-5 kV DC

Fully compliant with the European

harmonized EMI directive, EN50082-2,

and with the low voltage (safety)

directive, 73/23/EEC.

Features:

Air Insulated. Single printed circuit

board construction for easy access.

Air insulation for serviceability and

light weight.

Constant Voltage/Constant Current/

Current Trip Operation. Automatic

crossover from constant voltage

regulation to current control for

protection from overloads, arcs,

and shorts. Current control is user

configured for constant current

regulation or current trip.

Low Ripple. Better than 0.02% RMS

of rated voltage at full load.

Tight Regulation. Voltage regulation

better than 0.005%, line or load; current

regulation better than 0.1% from short

circuit to rated voltage.

Fast Transient Response. Less than 2

milliseconds for a 50% load transient.

Local Control and Indicator. Ten-turn

control for either voltage or current.

Power ON indicator.

Remote Interface Connections. Voltage

or current local control, voltage and

current program and monitor terminals,

current regulation/trip, TTL high voltage

enable, safety interlock terminals, +10

volt reference source, common, and

chassis ground.

Small Size and Weight. 3.375” (85.4 mm)

H x 7.25” (184.2) W x 16.00” (406) D.

Weight less than 11 pounds (5 kg.)

Output Connector and Cable. Choice

of Alden connector with unshielded

silicone wire or SHV connector with

RG-59 shielded cable.

Warranty. Standard power supplies

are warranted for three years; OEM

and modified power supplies are

warranted for one year. A formal

warranty statement is available.

Modules from 0 to 1 kV through 0 to 5 kV, 3.38" high x 7.25" wide x 16" deep.

SHV connector version shown, Alden connector available.

The MR Series…a sophisticated, medium power, high voltage power supply designed to

meet international safety approvals…is packaged as a space-saving module that avoids

the cost of expensive panels and displays. However, no compromises in performance

and operating features have been made. The result is a power supply that offers

outstanding value for a wide range of demanding applications.

Specifications
(From 5% to 100% rated voltage.  All
units operate down to zero output with
very slight degradation of performance.)
Input: 103-132 V RMS, 48-63 Hz single
phase, <6 A.  Connector per IEC 320
with mating line cord.
Efficiency:  Typically 85% at full load.
Output:  Continuous, stable adjustment,
from 0 to rated voltage or current by
panel mounted 10-turn potentiometer
with 0.05% resolution, or by external 
0 to 10V signals is provided.  Linearity
is <1% of rated.  Voltage accuracy is
0.5% of setting, 0.2% of rated.
Repeatability is <0.1% of rated. 
Stored Energy:  <0.5 joules.
Voltage Regulation:  <0.005% for line
variations.  For load variations, add 
1 mV/mA.
Ripple:  <0.02% RMS of rated voltage 
+ 300 mV RMS.
Current Regulation:  <0.1% of rated 
current from short circuit to rated 
voltage at any set current.
Voltage Monitor: 0 to + 10 V DC for
zero to rated voltage.  Accuracy, 0.5% 
of reading + 0.2% of rated voltage.
Current Monitor: 0 to + 10 V DC for 
zero to rated current.  Accuracy, 1% 
of reading + 0.05% of rated current.
Stability:  0.01% per hour after 1/2 hour
warm-up, 0.05% per 8 hours.
Voltage Rise/Decay Time Constant:
Typically 50 ms rise or decay time 
constant using TTL on/off or remote
voltage control with a minimum of 
15% resistive load.
Temperature Coefficient: 0.01%/
o
C.
Ambient Temperature: -20 to +40
o
C
operating, -40 to +85
o
C storage.
Polarity:  Positive or negative with
respect to chassis ground.
Protection: User-selected automatic 
current regulation or current trip 
protects against all overloads, 
including arcs and short circuits.  
Fuses, surge-limiting resistors, and 
low-energy components provide 
ultimate protection.
Accessories:  Detachable 8-foot HV
cable (see Models chart for choice of
output connector and cable type) and 
6-foot detachable line cord provided.
Remote Connections: Common, 
+10V reference, interlock, current 
program, current monitor, voltage 
program, voltage monitor, TTL HV
enable, current regulation/trip, and
chassis ground.
External Interlock: Open off, closed on.
HV Enable/Disable:  0-1.5 V off, 
2.5-15 V on.
