2.3 Unpacking and Examination
Our products are delivered carefully packed in cardboard boxes or in wooden crates, depending on place of
destination and the type of the device (dimensions, weight). We pay attention to the environmental compatibility of the
upholstery and packaging materials used and ask you to dispose the filling material correctly if present.
Please unpack the device and check the packaging as well as the product for transport damage. Should you notice
any damage to the packaging or the device, we ask you to log it with photos and inform us immediately.
ATTENTION: If the device has been delivered in a wooden box, please do not dispose it as it can be used for eventual
return transport for service procedures. Also the packaging material of smaller devices can be stored in order to be
used if necessary for a return transport.
3. Product Description
The DP-M power supply can operate in constant voltage (CV) or constant current (CC) mode within the rated output
range. This allows continuous switching between the modes in response to the load change.
In CV mode, a regulated output voltage is provided. The output voltage remains constant as the load increases while
the output current changes in response to the load changes, until the preset current limit is reached. At that point, the
output current becomes constant and the output voltage drops in proportion to the further increases in load. The
current mode is indicated on the front panel display.
Similarly in CC mode switching from CC to CV mode automatically occurs from a decrease of the load. A regulated
output current is provided. The output current remains constant as the load decreases while the output voltage
changes in response to the load changes.
3.1 Capacitive load
Note: Can be ignored for devices with optional passive reverse current protection.
In the basic version, power supplies of the DP-M series are not protected against reverse currents, which can lead to a
reverse current flowing from the capacitive load after switching off the output voltage of the power supply. Never
connect pre-charged capacities to the power supply unit unless you have connected a serial protection diode between
the load and the power supply. The protection diode is always recommended for operation with large capacities,
please pay attention to a correct dimensioning.
3.2 Pulse Load
Even if the peak current of the load is within the output power of the power supply, a high pulse load can cause
voltage fluctuations. To compensate these voltage fluctuations, expand your circuit by a serial induction. For low
currents, you can add a capacity in parallel for an even better result ( 1000uF / 1A).

DSC-Electronics Germany •Georgstraße 36 •53111 Bonn
DSC-Electronics Germany •Georgstraße 36 •53111 Bonn
3.3 Inductive load
Note: Can be ignored for devices with optional passive reverse current protection.
If the power supply is used with large inductive loads, voltage spikes with an amplitude of up to 5 times the output
voltage can occur, this may damage the power supply or lead to unstable operation. To protect the power supply from
damage, a freewheeling diode has to be used in parallel with the load.
3.4 Switches
If a mechanic switch is used to connect or disconnect the power supply from the load, electric discharge can occur
during switching on currents over 100A. This may cause unstable output. To prevent this behaviour, connect a RC
circuit to the switch contact point.

5.4 Preset Setup
The preset functionality can be used to save one set of current and voltage settings to quickly recall these during
operation.
1. Press the V-set key, then press the PRESET key to enter preset voltage mode. An underscore beneath the voltage
value and the PRESET icon will appear at the same time.
2. Tune the adjustment knob to set a desired voltage value.
3. Press OK key to confirm the above value. After confirmation, the underscore stops flashing, and the output voltage
changes to the newly preset value.
4. To change the value tune the adjustment knob again, the preset voltage value changes and the underscore flashes
again. The output voltage value changes only after pressing OK to confirm the newly preset value.
5. Repeat the same process using the I-set key, to change the current preset.
Note: If you set the preset values while the output is turned off, the output will not start with the preset values but will
use the normal set values instead. You can however apply the preset values instantly by pressing the OK key or the

Remark 1:
Supported baud rates: 1200; 2400; 4800; 9600; 14400; 19200; 38400; 43000; 57600; 76800; 115200; 128000
Due to the limitation of single register data range (0~65535), the baud rate needs to be divided by 10, that is, remove a
0 at the end and write it.
