Output
Connection
Output Front panel, 2 ea. 4 mm safety jacks
Rear , 6-pole plug-in screw terminal block
Sensor Rear panel, included in 6-pole plug-in
screw terminal block
Analog interface Rear, 11-pole plug-in screw terminals
Regulator type Primary switched-mode regulator with
BET technology
Operating modes Adjustable constant voltage / constant
current source with automatic sharp
transition
Output isolation Floating output with “safe electrical
separation” from the mains input and
computer interfaces
Max. allowable potential, output–ground:
120 V, capacitance, output–ground
(housing) 60 nF
Output operating range
Short-term range:
If lengthy operation in the short-term
range occurs, overtemperature protec-
tion may be triggered resulting in output
shutdown (see also short-term power in
chapter 1.5.3).
