1 Technical Description
1.1 Range of Applications and Features
The SLP-KONSTANTER is a single channel laboratory power supply
for universal use in R&D, production, training and service.
The KONSTANTER maintains either constant current or constant voltage
and is capable of delivering 120 W or 240 W of nominal power
over a broad range thanks to the auto-ranging output.
Precise manual settings for voltage and current are accomplished
with the help of ten-turn potentiometers. The setting range can be
reduced with a screwdriver, in order to prevent inadvertent
adjustment to unwanted, excessively high values.
Output voltage and current appear at two large-format 3½ place
digital LED displays, which can also be switched for the display of
setpoint values. Control mode displays indicate the respective
operating status.
The floating output at the front and rear panels can be activated and
deactivated by pressing a key, or with a signal to the analog inter-
face which is provided as standard equipment. The instrument is
automatically switched to remote sensing as soon as sensor cables
are connected.
The sturdy metal housing is sealed at top and bottom, and is
equipped with rubber feet and a cable spacer at the rear panel.
With a minimum of effort, several housings can be mechanically
combined into a multi-channel unit. This unit requires only one
mains outlet which is looped through with the help of a mains
jumper cable (accessory) via the integrated mains outlet socket.
Installation to a 19" rack is also possible with the appropriate
adapter.
