As with other DC power supply products from Glassman, the KL series features notable technology benefits including 1: Glassman’s proprietary air-insulation technology—where air is used as the primary dielectric medium, in comparison to competitive models that utilize silicon rubber, epoxy or oil. Air offers distinct advantages from both a long-term reliability standpoint and serviceability over the extended life of the product. 2. Robust circuits that handle arcing and short circuit conditions in dynamic environments that will not compromise reliability or long lasting performance. This feature makes the KL ideal for use with Web coaters , E-Gun/Ion sources and Accelerator applications to name a few. The KL can also be used as a reliable, general laboratory high voltage power supply.

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

Power-factor Corrected. Active correction circuitry achieves a full load power factor of better than 0.99.

Low Stored Energy. Most models exhibit less than 4 joules of stored energy.

High Speed Dynamic Voltage Regulation. Rapid responding control circuits provide a typical response of less than 500 µs to load transients.

Single-phase Input. Full 3kW output from a single-phase, 198-264 V, 48-63 Hz input, 3500 VA maximum.

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

Air insulated. The KL Series features "air" as the primary dielectric medium. Assemblies use no oil or encapsulation that could impede serviceability 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.

Tight Regulation. Voltage regulation is better than 0.005% for allowable line variations and 0.01% for load variations. Current regulation is better than 0.05% from short circuit to rated voltage.

Front Panel Controls (Digital and Optional Analog Versions.) Separate 10-turn controls with locking vernier dials are used to set voltage and current levels. A high voltage enable (on) switch, a high voltage disable (off) 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.

Small Size and Weight. KL Series power supplies occupy only 7 inches of panel height. Net weight is less than 50 pounds.

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: 198-264 V RMS, single-phase, 48-63 Hz, 3500 VA maximum, <16A at 220 V. A 3-position terminal block with protective cover is provided.

Efficiency: Typically 87% at full load. Power factor >0.99.

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 0.01% + 0.2 volts per ampere 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 1ms.

Ripple: <0.02% of rated voltage + 500 mV RMS.

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% reading +0.5% rated.

Current Monitor: 0 to + 10 V equivalent to 0 to rated current. Accuracy, 1% reading +0.05% rated for single polarity, 1% reading + 0.1% rated for reversible polarity.

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 10% resistive load using either HV on/off or remote programming control.

Temperature Coefficient: 0.01% per degree C.

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

Remote Controls: Terminal block is provided for all remote functions including common, +10V reference, interlock, voltage and current program/monitor, HV Enable/Disable, ground, and local control.

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

HV Enable/Disable: 0-1.5 V off. 2.5-15 V on.
