ER Series 300 Watt Regulated High Voltage DC Power Supplies

Product catalog summary

Overview: The ER Series 300 Watt Regulated High Voltage DC Power Supplies are designed for laboratory performance with high power density and enhanced features. They are fully compliant with European EMI and low voltage safety directives.

Key Features:

Air Insulated: Utilizes air as the primary dielectric medium, avoiding oil or encapsulation.
Operation Modes: Automatic crossover between constant voltage and constant current modes based on load conditions.
Low Ripple: Less than 0.02% of rated voltage at full load.
Tight Regulation: Voltage regulation better than 0.005% and current regulation better than 0.05%.
Fast Transient Response: Less than 3 milliseconds for a 50% load transient.
Control Options: Available in analog and digital versions with ten-turn voltage and current controls.
Remote Control Facilities: Includes output voltage and current program/monitor terminals, TTL high voltage enable/disable, and safety interlock terminals.
Compact Design: Occupies only 3.5 inches of vertical panel height and weighs 18 pounds.
Warranty: Standard models have a three-year warranty, while OEM and modified models have a one-year warranty.

Specifications:

Input: 105-125 V RMS, 48-63 Hz single phase, <6 A.
Efficiency: Typically 85% at full load.
Output: Continuous, stable adjustment from 0 to rated voltage or current.
Stored Energy: 20 kV model has 1.5 joules; 60 kV model has <4 joules.
Voltage Regulation: <0.005% +1mV/mA, line and load.
Ripple: <0.02% RMS of rated voltage +0.5V at full load.
Current Regulation: <0.1% from short circuit to rated voltage.
Stability: 0.01% per hour after 1/2 hour warm-up, 0.05% per 8 hours.
Temperature Coefficient: 0.01%/°C.
Protection: Automatic current regulation protects against overloads, including arcs and short circuits.

Models and Options:

Models range from 0 to 1kV through 0 to 75kV with various output currents and cable types.
Options include different input voltages, digital meters, current trip, zero start interlock, slow start ramp, and reversible polarity.
