CONDITIONS

This document contains specifications and supplemental information for the Model 2290-5 High Voltage Power Supply. Specifications are the standards against which the Model 2290-5 is tested. Upon leaving the factory, the Model 2290-5 meets these specifications. Characteristics, supplemental characteristics, and typical values are not warranted, apply at 23 °C ± 5 °C, < 70% relative humidity, and are provided solely as useful information.

CHARACTERISTICS

Voltage range: Output voltage1 Maximum output current Conditions

50 to +5000 V dc 5.000 mA DC No filter 50 to +3000 V DC 5.000 mA DC Filter 1 50 to +5000 V dc 3.000 mA DC Filter 2

Voltage set accuracy2: ±(0.01% of setting + 2.5 V) Voltage display accuracy: voltage set accuracy ±1 V, typical (±2 V, maximum) Voltage resolution: 1 V (set and display) Voltage limit range: 0 to 100% full scale Voltage regulation3:

Line: 0.001% for ±10% line voltage change Load: 0.005% for 100% load change, typical

Output ripple (10 kHz – 100 kHz)4:

0.002% of full scale, V RMS, maximum - No filter

1.0 mV RMS @ 1 kV – Filter 1 or Filter 2

2.0 mV RMS @ 3 kV – Filter 1 or Filter 2

3.0 mV RMS @ 5 kV – Filter 2

Rise time (full load)

5, 6

1.5 seconds for 0 V setting to within 1 V of 5000 V DC – No filter 3 seconds for 0 V setting to within 1 V of 3000 V DC – Filter 1 4 seconds for 0 V setting to within 1 V of 5000 V DC – Filter 2

The output voltage can be programmed to a voltage lower than 50 V, however, performance below 50 V is not specified.

Add ±2.5 V DC when Filter 1 or Filter 2 is enabled.

Regulation specifications apply for greater than 25 V DC (with full load), or 50 V DC (with no load). Below these values, the unit may not

regulate correctly.

Peak-to-peak values are within five times the RMS value.

Current limit set to 105% of full scale.

Under resistive load.
