MR Series 300 Watt Regulated High Voltage	PDF Print Version HTML Print Version
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.			Modules from 0 to 1 kV through 0 to 5 kV, 3.38" high x 7.25" wide x 16" deep (excluding interface connections). SHV connector version shown, Alden connector available.

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.

(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. Accuracy is 0.25% of rated + 1% of setting. Repeatability is <0.1% of rated.

Stored Energy: <0.5 joules.

Voltage Regulation: <0.005% for line variations. For load variations, add 1mV/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, 1% of reading +0.25% 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%/oC.

Ambient Temperature: -20 to +40oC operating, -40 to +85oC 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.
