DMM Isolation Voltages
Hazardous Voltage
This icon denotes a warning advising you to take precautions to avoid electrical shock.
Channel-to-earth ground
Continuous
300 V, Measurement Category II
Withstand
3,000 V RMS, verified by a 5 s dielectric withstand test
Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level
electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.
Caution
Do not connect the VirtualBench hardware to signals or use for measurements within Measurement Categories III or IV.
DC Power Supply Isolation Voltages
+25 V and -25 V-to-earth ground, continuous
60 V DC, Measurement Category I
Note
Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct
connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.
Power Requirements
Caution
The protection provided by the VirtualBench hardware can be impaired if it is used in a manner not described in the
NI VirtualBench
VB-8054 Safety, Environmental, and Regulatory Information
.
Voltage input range
100 V AC to 240 V AC, 50/60 Hz
Power consumption
150 W maximum
Power input connector
IEC C13 power connector
Power disconnect
The AC power cable provides main power disconnect. Do not position the
equipment so that it is difficult to disconnect the power cable. Depressing the
front panel power button does not inhibit the internal power supply.
Preparing the Environment
Ensure that the environment you are using the VB-8054 in meets the following specifications.
Operating temperature
0 °C to 40 °C
Cooling
Forced air circulation (negative pressurization) through a fan. Fan speed
automatically adjusts according to operating conditions. Intake locations are on
the sides of device. Exhaust location is on the rear of device. Ensure that the
intake and exhaust locations are not obstructed.
Pollution Degree
2
Maximum altitude
2,000 m
Indoor use only.
Note
Refer to the
NI VirtualBench VB-8054 Specifications
for complete specifications.
