BHK 2000-0.1MG
Chassis connection to ground
resistance 100 mohms max. Between ground input connection and
chassis @ 30A
Leakage Current 25
µ
A rms /100 uA p-p, for 115V a-c input voltage
(chassis to EARTH-GND)
Enable/Disable Output Power Local Front panel Keypad Enables/disables digital programming sig-
nals only. Shutdown line is for disable only
- removing the signal does not reenable
the output (See PAR. 3.2.7.3).
Remote - IEEE 488 (GPIB) port
- RS 232 port
- Trigger port (shutdown
line)
Output Display Output voltage is displayed with two decimals for BHK 300-0.6MG and
BHK 500-0.4MG and one decimal for BHK 1000-0.2MG and BHK
2000-0.1MG.Output current for all models is displayed with two deci-
mals when current range is set to High, and three decimals when cur-
rent range is set to Low.
Protection Overtemperature: See PAR. 1.4.10a
Overvoltage/Overcurrent: 0 to 1.1 x EOmax
0 to 1.1 x IOmax (except
BHK 300-0.6MG)
0 to 1.08 x IOmax (BHK
300-0.6MG only)
See PAR. 1.4.4
