Models from 0 to 1 kV through 0 to 150 kV. The LT Series are 2000 watt sophisticated, well-regulated, high voltage DC power supplies. Rack-panel height is only 8.75 inches. The LT is offered with dual analog voltage and current meters or, optionally, with dual digital meters or a blank panel for OEM/systems applications. Features: Pulse-Width Modulation. Off-the-line pulse-width modulation provides high efficiency and a reduced parts count for improved reliability. Air Insulated. The LT Series features “air” as the primary dielectric medium. No oil or encapsulation is used to 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 0.03% of rated voltage at full load. Tight Regulation. Voltage regulation is better 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 (Analog and Digital Versions.) Separate 10-turn controls with locking vernier dials are used to set voltage and current levels. A high voltage enable 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. LT Series power supplies occupy only 8.75 inches of panel height. Net weight is less than 47 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. Specifications (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, <20 A. A 3-position terminal block with protective cover is provided. Efficiency: Typically 85% at full load. Output: Continuous, stable adjustment, from 0 to rated voltage Options Symbol Description 200 200 V ± 10% input, 48-63 Hz. Derate currents by 10%, maximum 1800 W. DM 3-1/2 digit LCD panel meters. NC Blank front panel, power switch only. CT Current trip. Power supply trips off when the load current reaches the programmed level. This option has a rear panel switch that selects either “trip” operation or current limiting. ZR Zero start interlock. Voltage control, local or remote, must be at zero before accepting an enable signal. 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 set- ting + 0.2% of rated. Repeatability is <0.1% of rated. Stored Energy: <15 Joules, 60 kV; <30 Joules, 125 kV. Voltage Regulation: Better than 0.005% for specified line variations and 0.005% + 1 mV/mA for load variations. Ripple: <0.03% of rated voltage + 1 V RMS at full load (0.1% for 150kV). 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 + 0.2% 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 to 60 kV (400 ms for higher voltages) with a 30% 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. Accessory: Detachable 8-foot HV cable. See Models chart for cable type. Remote Controls: Terminal block is provided for all remote functions, includ- ing common, +10 V 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. +81 45 902 9988 FAX +81 45 902 2268 Printed in the U.S.A. B 12/18/2003
