KL Series 3000 Watt Regulated High Voltage DC Power Supplies

Product catalog summary

Overview: The KL Series 3000 Watt Regulated High Voltage DC Power Supplies are designed to meet high power and high voltage demands with a power factor corrected to greater than 0.99, complying with EN61000-3-2 specifications. These supplies are fully compliant with European EMI and safety directives.

Key Features:

Power Factor Correction: Active circuitry achieves a power factor better than 0.99.
Low Stored Energy: Models exhibit less than 4 joules of stored energy.
Dynamic Voltage Regulation: Rapid response to load transients with a typical response time of less than 500 µs.
Single-phase Input: Operates on a 198-264 V, 48-63 Hz input, with a maximum of 3500 VA.
Pulse-Width Modulation: Provides high efficiency and reliability.
Air Insulated: Uses air as the primary dielectric medium, enhancing serviceability and reducing weight.
Constant Voltage/Current Operation: Automatic crossover for protection against overloads and short circuits.
Low Ripple: Less than 0.02% of rated voltage at full load.
Tight Regulation: Voltage regulation better than 0.005% for line variations and 0.01% for load variations.
Front Panel Controls: Digital and optional analog versions with separate controls for voltage and current levels.
Compact Size: Occupies only 7 inches of panel height and weighs less than 50 pounds.
Warranty: Standard models have a three-year warranty; OEM and modified models have a one-year warranty.

Specifications:

Input: 198-264 V RMS, single-phase, 48-63 Hz, <16A at 220 V.
Efficiency: Typically 87% at full load.
Output: Continuous adjustment from 0 to rated voltage or current with high accuracy and repeatability.
Dynamic Voltage Regulation: Typical deviation of 2% with recovery to within 1% in 500 µs.
Ripple: Less than 0.02% of rated voltage + 500 mV RMS.
Current Regulation: Better than 0.1% from short circuit to rated voltage.
Stability: 0.01% per hour after 1/2 hour warmup.
Temperature Coefficient: 0.01% per degree C.
Protection: Automatic current regulation with fuses and surge-limiting resistors.

Options:

200 V Input: Derate currents by 10%, maximum 2700 W.
Analog Panel Meters: Dual analog meters available.
Current Trip: Power supply trips off at programmed current level.
Zero Start Interlock: Voltage control must be at zero before enabling.
Slow Start Ramp: Specify standard times from 1 to 30 seconds.

Models: Various models available with different voltage and current ratings, including reversible polarity options.
