5.1. Intended use

• The laboratory power supply unit serves as a potential-free DC voltage source to operate low-voltage consumers.
It has three independent outputs. An adjustable laboratory output, an adjustable USB output and a processor-
controlled USB output.
• When switching the outputs of several power supplies in series, voltages of >70 V/DC may be generated, which
are dangerous to touch. Above this voltage, insulated lines/measuring cables must be used for safety reasons. The
devices are connected via 4 mm safety sockets.
• The output data of the laboratory power supplies is as follows:
Item name
VLP 1303 USB
VLP 1405 USB
VLP 1602 USB
• The voltage and current strength can be continuously adjusted at output A and B1-USB. The voltage and current
values of output B1-USB are displayed with the push of a button on the display of output A.
• Output B2-USB is processor-controlled and always automatically selects the best output parameters for the termi-
nal device connected.
• Voltage and current adjustments are via a precise adjuster. The voltage regulator for output A is a multi-turn poten-
tiometer for precise settings. The values are displayed on a concise LC display.
• The current limitation for constant current mode can be preset with the push of a button. A short-circuit jumper at
the output is not required during setting.
• For output A, a voltage limitation (OVP) can be set for safety purposes. When this adjustment level is achieved, the
output is switched off automatically. This prevents the accidental destruction of connected consumers due to an
excessively high output voltage.
• The device is overload and short-circuit-proof and contains a safety temperature cut-off.
• The laboratory power supply is designed in compliance with protection class 1. It is only approved for connection to
protective sockets and an alternating current of 230 V/AC commonly used in households. The earth potential socket
is directly connected to the protective earth on the mains plug.
• The mains socket to which the product is connected must be easily accessible.
• Operation under adverse ambient conditions is not permitted. Adverse conditions include: Damp or excessively
high humidity, storms or stormy conditions such as strong electrostatic fields, etc.
• Do not use the product in environments where there are high levels of dust, flammable gases, vapours or solvents.
This may cause a fire or explosion!
