and current resolution as entirely meeting customer' s demanding.
5) OVP (over voltage protection), OCP (over current protection) and OPP
(over power protection) and key lock functions
The over voltage protection (OVP), over current protection (OCP) and over
power protection (OPP) features limit the maximum output current and
voltage to avoid damages to the test objectives when doing
experimentations in a laboratory. The key lock feature disables all keys
except the CLR key. It prevents DS3640/DS6024/DS8018/DS10014 from
the accidentally wrong setting and then avoids the damages to the target.
6) Series & parallel connection mode
The series-parallel connection mode of two or more units (maximum to 4
units) largely increases product's power-supplying capability. Under the
parallel connection mode of four DS3640 the maximum output is
36V/160A; and under the cascaded connection mode of four DS10014, the
maximum output is 400V/14.4A. Power supplied under these two modes
reach up to 5760 watts output that can meet most electric experiments'
demands.
7) Multi-units series connection mode
Computer can connect to system through USB interface. RS485 interface
can be used to connect 31 units at most. It can save GPIB interface card and
GPIB wiring expense and simplify the connection control.
