EL Series 40-45 Watt Regulated High Voltage DC Power

Product catalog summary

Overview: The EL Series offers 40-45 Watt regulated high voltage DC power supplies designed for laboratory performance, providing up to 60kV DC. These units are compact, weighing a maximum of 12 pounds, and are economically priced.

Compliance: Fully compliant with European harmonized EMI directive EN50082-2 and low voltage directive 73/23/EEC. Line harmonics meet EN61000-3-2 specifications.

Key Features:

Low Ripple: Better than 0.03% RMS at full load.
Air Insulated: Uses air as the dielectric medium, enhancing serviceability and reducing weight.
Low Stored Energy: Less than 800 millijoules for most models.
Fast Acting Current Limiting: Automatic crossover circuit for overload protection.
Tight Regulation: Voltage regulation better than 0.005%.
Low Transient Response Time: Less than 3 milliseconds for a 50% load transient.

Front Panel Elements: Includes a ten-turn voltage control with locking vernier dial, analog displays for voltage and current, and an illuminated AC power on/off switch.

Protection: Overload, short circuit, and arc protection through automatic current limiting and surge-limiting design.

Warranty: Standard power supplies have a three-year warranty; OEM and modified supplies have a one-year warranty.
