Line Power Requirements; System Power Dissipation; Environmental Conditions - Keithley S500 Administrative Manual

Line power requirements

Nominal*: 100V, 115V, 220V, 240V (50Hz, 60Hz)
Power consumption: Rated at 1.8kVA for the 1.5KW PDU and 2.4kVA for the 2KW PDU.
NOTE There could be up to 2 PDUs in a system depending on the configuration.

System Power Dissipation

NOTE This applies to the S500 only.
The total power dissipated by the S500 is a function of the type and number of instruments; however, the power
distribution unit (PDU) limits the incoming power to these instruments. While the PDU ensures electrical safety and
compliance to the required standards, it does not prevent the system from over heating. Specifically, a large
number Series 2600 SourceMeter
exceeding the maximum specified operating temperature of the instruments within the cabinet. When a Series 2600
instrument detects and excessive heat condition, the unit turns the output off to minimize power dissipation. This
safeguard prevents damage to individual 2600 instruments, but may result is test instability.
Additional details on 2600 overheating protection can be found in the Series 2600 System SourceMeter
Manual in the Overheating Protection section of the Source-Measure Concepts section.

Environmental conditions

The S500 will not perform within specifications if operated outside of the following environmental conditions:
Temperature: 23°C ±5°C (73.4°F ±9°F)
Operating humidity: 5 to 60% RH, noncondensing
Vibration: High ambient vibration levels may require isolation pads or the repositioning of equipment.
Air quality: The S500 system is compatible for use in a Class 10 cleanroom.
Altitude: Less than 2000 meters above sea level.
Noise interference — To prevent electrical noise from interfering with measurements, the ambient AC magnetic
field must not exceed 2 x 10-3 gauss.
Avoid locating the S500 next to plasma etchers, large motors, magnets, RF transmitters, equipment with
flash lamp, or other sources of potential interference.
Run power lines in grounded conduit.
Avoid routing signal and power cables near sources of electrical noise. Position the equipment
accordingly.
