FX Series 300 Watt Regulated High Voltage DC Power Supplies	PDF Print Version HTML Print Version
Models from 0 to 1kV through 0 to 60kV, 1.75” H x 19” W x 20.25” D, 14 lbs.
Fully compliant with the European harmonized EMI directive, EN50082-2, and with the low voltage (safety) directive, 73/23/EEC. With the PFC option, line harmonics are within the European harmonized standard, EN61000-3-2 specifications.			1 to 60kV 1.75" Panel CE Compliant

The FX series is particularly suited for applications where size is critical in terms of meeting system mechanical requirements. Applications include DC Bias for Vacuum process equipment, Microwave systems and Accelerator Research to name a few.

The FX series is CE Mark certified and can be utilized with the RS-232 digital interface option, which is now available for most of Glassman’s standard models. Glassman also offers a comprehensive three-year warranty and post-sale support from its staff of application engineers.

Arc Quench. The HV output is inhibited for a short period after each load arc to help extinguish the arc.

Arc Count. Internal circuitry constantly senses and integrates arcs that occur over a given time. In the event a system or load arcing problem develops and exceeds factory-set parameters, the power supply will cycle off in an attempt to clear the fault and then automatically restart after a preset "off dwell time".

Low Stored Energy. Most models exhibit less than 3 joules of stored energy.

Pulse-Width Modulation. Off-the-line-pulse-width modulation provides high efficiency and a reduced parts count for improved reliability.

Air Insulated. The FX Series features “air” as the primary dielectric medium. No oil or encapsulation is used to impede service-ability or increase weight.

Constant Voltage/Constant Current Operation. Automatic crossover from constant- voltage to constant-current regulation provides protection against overloads, arcs, and short circuits.

Low Ripple. Ripple is less than 0.02% of rated voltage at full load than 0.005% for allowable line and load variations. Current regulation is better than 0.05% from short circuit to rated voltage.

Front Panel Controls. Separate 10-turn controls with locking vernier dials are used to set voltage and current levels. A high voltage enable (on) switch and an AC power on/off switch complete the panel controls. L.E.D.’s indicate when high voltage is on, the output polarity, and whether the supply is operating in a voltage or current regulating mode. For the blank panel version, only a power on/off switch is provided on the panel.

Remote Control Facilities. As standard, all FX Series supplies provide output voltage and current program/monitor signals, high voltage enable, safety interlock terminals, and a +10 volt reference source.

Small Size and Weight. FX Series power supplies occupy only 1.75 inches of panel height. Net weight is less than 14 pounds.

Warranty. Standard power supplies are war-ranted for three years; OEM and modified power supplies are warranted for one year. A formal warranty statement is available.

(Specifications apply from 5 to 100% rated voltage. Operation is guaranteed down to 0% of rated voltage with a slight degradation in performance.)

Input: 102-132V RMS, single-phase, 48-400 Hz, <6 A. Connector per IEC 320 with mating line cord terminated with NEMA 5-15 plug.

Efficiency: Typically 85% at full load.

Output: Continuous, stable adjustment, from 0 to rated voltage or current by panel mounted 10-turn potentiometers with 0.05% resolution, or by external 0 to 10V signals is provided. Voltage accuracy is 0.5% of setting +0.2% of rated. Repeatability is <0.1% of rated.

Stored Energy: See Models chart.

Static Voltage Regulation: Better than 0.005% for specified line variations and 0.005% + 0.5 mV/mA for load variations.

Dynamic Voltage Regulation: For load transients from 10% to 100% and 100% to 10%, typical deviation is 2% of output voltage with recovery to within 1% in 500 µs and to 0.1% in 1 ms.

Ripple: <0.02% of rated voltage plus 500mV RMS at full load.

Current Regulation: Better than 0.1% from short circuit to rated voltage at any load condition.

Voltage Monitor: 0 to +10 V equivalent to 0 to rated voltage. Accuracy, 0.5% of reading +0.2% rated.

Current Monitor: 0 to +10 V equivalent to 0 to rated current. Accuracy, 1% of reading +0.05% rated except reversible models: 1% of reading + 0.1% of rated.

Stability: 0.01% per hour after 1/2 hour warmup, 0.05% per 8 hours.

Voltage Rise/Decay Time Constant: 50 ms typical with a 50% resistive load using either HV on/off or remote programming control.

Temperature Coefficient: 0.01% per degree C.

Ambient Temperature: -20 to +40 degrees C, operating; -40 to +85 degrees C, storage.

Polarity: Available with either positive, negative, or reversible polarity with respect to chassis ground.

Protection: Automatic current regulation protects against all overloads, including arcs and shorts. Fuses, surge-limiting resistors, and low energy components provide ultimate protection.

Arc Quench: An arc quench feature provides sensing of each load arc and quickly inhibits the HV output for approximately 20 ms after each arc. Standard on 8 - 60 kV models; optional on 1 - 6 kV models.

Arc Count: Internal circuitry senses the number of arcs caused by external load discharges. If the rate of consecutive arcs exceeds approximately one arc per second for five seconds, the supply will turn off for approximately 5 seconds to allow clearance of the fault. After this period the supply will automatically return to the programmed kV value with the rise time constant indicated. If the load fault still exists, the above cycle will repeat. Standard on 8 - 60 kV models; optional on 1 - 6 kV models.

Remote Controls: A three position terminal block and a 15 Pin “D” connector are provided for all remote functions, including common, +10 V reference, interlock, voltage and current program/monitor, HV enable, ground, and local control. A rear panel toggle switch selects either local or remote operation.

External Interlock: Open off, closed on. Normally latching except for blank panel version where it is non-latching.

Remote HV Enable: 0-1.5 V off, 2.5-15 V on.

Accessories: Detachable 8 foot shielded high voltage coaxial cable (see Models chart for cable type), 6 foot detachable line cord, and mating 15 Pin “D” connector and shell are provided.
