Between shorted inputs and chassis
BHK 300-130MG 1950V d-c/1 min
Between shorted outputs and chassis.
BHK 500-80MG 2250V d-c/1 min
BHK 1000-40MG
2800V d-c/1 min
BHK 2000-20MG
Chassis connection to ground
resistance
0.1 Ohm max.
Between ground input connection and
chassis @ 30A
Leakage Current
25
A rms /100 uA p-p, for 115V a-c input voltage
(chassis to EARTH-GND)
Enable/Disable Output Power
Local Front panel Keypad: disable both digital and analog programming sig-
nals.
Remote - IEEE 488 (GPIB) port
- RS 232 port
- Status & Remote On/Off
port
- TTL signal
- NO relay contact
- NC relay contact type.
- Trigger port (shutdown line)
Disables both digital and analog pro-
gramming signals. Shutdown line is for
disable only - removing the signal does
not reenable the output.
Output Display
Two decimal places are used for voltage settings and three decimal
places for current settings (except that only one decimal place is used
for setting voltage on Models BHK 1000-40MG and BHK 2000-20MG).
