WK Series Extended Current 500 Watt Regulated High Voltage DC Power Supplies

Product catalog summary

Overview: The WK Series is a line of 500 Watt regulated high voltage DC power supplies, offering output voltages up to 125kV. These units are designed for laboratory performance with a compact 5.25-inch panel height and a weight of less than 30 pounds.

Compliance: Fully compliant with the European harmonized EMI directive EN50082-2 and the low voltage directive 73/23/EEC.

Key Features:

Extended Current: Maximum current ratings equivalent to a 600W supply for voltages up to 84% of rated output, with derating above this point to maintain a 500W maximum output.
Pulse-Width Modulation: Provides high efficiency and reduced parts count for improved reliability.
Constant Voltage/Current Operation: Automatic crossover for protection against overloads, arcs, and short circuits.
Low Ripple: Less than 0.1% of rated voltage at full load.
Tight Regulation: Voltage regulation better than 0.005%, and current regulation better than 0.1%.
Front Panel Controls: Includes separate 10-turn controls for voltage and current, high voltage enable switch, and AC power on/off switch.
Air Insulated: For improved serviceability and decreased weight.

Specifications:

Input: 102-132V RMS, 48-63Hz single phase, <10 A.
Efficiency: Typically 83% at full load.
Output: Continuous, stable adjustment from 0 to rated voltage or current.
Voltage Regulation: <0.005%, line or load.
Ripple: <0.1% RMS of rated voltage at full load.
Current Regulation: <0.1% of full scale from short circuit to rated voltage.
Stability: 0.01% per hour after 1/2 hour warmup, 0.05% per 8 hours.
Temperature Coefficient: 0.01% per degree C.
Ambient Temperature: Operating: -20 to +40 degrees C; Storage: -40 to +85 degrees C.
Protection: Automatic current regulation, fuses, surge-limiting resistors, and low-energy components.

Options:

Various input voltage options (90-116V, 180-232V, 200-264V, 48-420Hz).
Digital meters, blank front panel, current trip, zero start interlock, slow start ramp, and 0-5V program/monitor options.

Models: Available in positive, negative, and reversible polarities with different voltage and current specifications, all limited to a 500W maximum output.

Warranty: Standard power supplies are warranted for three years; OEM and modified power supplies for one year.
