Models from 0 to 40 kV through 0 to 100 kV, 8.75" H x 24.0" D, 55 lbs.
			100 kV to 400 kV Overload Protected

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

Air Insulation. Both PG series feature "air" as the primary dielectric medium. No oil or encapsulation is used that could impede serviceability or increase weight.

Constant Voltage/Constant Current Operation. Automatic crossover from constant-voltage to constant-current regulation serves to protect the supplies from overloads, arcs, and short circuits.

Tight Regulation. Voltage regulation is better than 0.005% for allowable line and load variations. Current regulation is better than 100 µA from short circuit to rated voltage.

Ripple. Standard models better than 0.1% at full load. For the extremely low ripple values of the PG-LR series, see the models chart.

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: Series PG: 105-125 V RMS, single-phase, 48-63 Hz, <15 A. Series PG-LR: 187-230 V RMS, 3-phase, 48-63 Hz, < 5 A per phase.

Efficiency: Typically 75% 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 10 V signals is provided. Linearity is <1% of rated. Accuracy is 1% of rated +1% of setting. Repeatability is <0.1%
of rated.

Voltage Regulation: Better than 0.005% + 1 V, line or load.

Ripple: Better than 0.1% of rated voltage at full load. Series PG-LR: See models chart.

Current Regulation: Better than 100 µA from short circuit to rated voltage for any load condition; 0.005% + 1 µA for line variations.

Voltage/Current Monitor: Zero to +10 V signal for zero to rated voltage/current.

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

Temperature Coefficient: 0.01% per degree C + 1 V.

Ambient Temperature: -20 to +60 degree C, operating; -40 to +85 degree C, non-operating.

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

Protection: Automatic current regulation protects the power supply against all overload conditions, including arcs and short circuits. Fuses, surge-limiting resistors, and low energy components provide the ultimate protection.

External Interlock: Open off, closed on.
