556 and 556H high voltage power supplies

Output polarity

Positive or negative, selected by switch on rear panel.

Output range

50to3000 V;Minimum available voltage10 V。

Output load capacity

0to10 mA。

Adjustment rate

For combined line and load changes over the operating range at constant ambient temperature, the output voltage changes ≤0.0025％。

temperature instability

preheat30minutes later<±50 ppm/°C; Scope of work0to50°C。

long term drift

preheat30After minutes, the output voltage varies at constant input line voltage, load, and ambient temperature<0.01％/hours and<0.03％/24hours.

Output ripple

peak to peak<15 mV，20 Hzto20 MHz。

Overload protection

Internal circuitry protects against overloads and short circuits.

Adjustability

The output voltage can be reset to0.1Within %.

power supply

When the power cord is connected to an appropriate power source, the front panel toggle switch powers the device, adjacent the redLEDLights will indicate when power is on.

Output voltage

one6bit switch, one5bit switch and a10circle precision potentiometer; the output voltage is3The sum of all settings.

instrument

The front panel toggle switch can select the display toVoutput voltage in units or inmAis the load current in units.

polarity

Rear panel switch selects positive and negative output polarity.

control

A rear panel locking toggle switch selects the reference source for the output voltage.

• Int Selects the internal reference source; front panel controls select the output voltage.
• Ext Select an external reference source; the output voltage is proportional to the size of the reference input.

AC voltage

Rear panel slide switch optional115 Vor230 VAC input voltage.

AC power

103-129 Vor206-258 V，47-63 Hz, at full output power, nominal70 W;By international standards on the rear panelIECPower connector supplies power. Fuse rating:1.5 A，250 Vfuse for115 V ACoperation or0.75 A，250 Vfuse for230 V ACoperation.

external controls

The full range of output voltages can be based on via the rear panelBNCExternal DC reference level provided by the connector; the voltage range of the control is0to±6.9 V DC;The voltage polarity of the control must be the same as that selected by the rear panel polarity switch; this input protects against overvoltage>±7 V. Input impedance>45kΩ。

Stabilized DC output

Adjusted and regulated voltage with selected polarity is supplied simultaneously to both rear panelSHVconnector.

instrument
